CHAPTER
1
Introduction to TraceX
TraceX is a Microsoft system analysis tool that
displays system event information gathered by
ThreadX running on an embedded target. The user is
responsible for transferring the trace buffer stored in
RAM in the embedded target to a binary file on the
host computer. The user can then open this file with
TraceX and graphically analyze the target events,
diagnosing system problems and tuning a working
application to improve performance and resource
management.
This chapter describes the following:
1
TraceX Requirements 12

TraceX Constraints 12
Express Logic, Inc.

Introduction to TraceX
TraceX Requirements
TraceX requires Windows XP (or above). The system
should have a minimum of 192MB of RAM, 2 GB of
available hard-disk space, and a minimum display of
1024x768 with 256 colors. In addition, the application
must be running on ThreadX V5.0 or later.
TraceX also requires the Microsoft .NET framework
be installed, which the TraceX installer does
automatically.
TraceX Constraints
TraceX has the following constraints:
• TraceX files are limited to a maximum of 32,768
events (roughly 1MB ).
• The time-stamp source must have reasonable
resolution. If the resolution is too low, the events
will overlap. If the resolution is too high, there is
potential for long gaps between events.
• TraceX cannot accurately measure intervals
between events greater than the timer period.

Installation and Use of TraceX
Product Distribution
TraceX is shipped on a single CD-ROM compatible
disk. The package includes an installation program
Setup.exe that automatically runs from the CD. If the
TraceX installer does not automatically run, click on
the Setup.exe program manually to install TraceX.
The TraceX package also contains an example
directory of pre-built traces that should serve as a
good starting point for new TraceX users.
The release notes associated with each new TraceX
release can be found in the file readme_tracex.txt.
Review this file to see what has changed between
successive TraceX releases.
TraceX Installation Directory
TraceX, by default, is installed in the directory
c:\ExpressLogic\TraceX_v, where v is the version
of TraceX being installed. The default location for
TraceX installation may be changed via the installation dialog as shown in the next section.
TraceX requires the Microsoft .NET framework to
operate.The installation of this is done automatically
by the TraceX installer via the dialogs shown later in
this chapter.

Installation and Use of TraceX
Using TraceX
Using TraceX is as easy as opening a trace file
inside TraceX! Run TraceX via the Start button. At
this point you will observe the TraceX graphic user
interface (GUI). You are now ready to use TraceX to
graphically view an existing target trace buffer. This
is easily done by clicking File -> Open, then entering
the binary trace file.
You can also double-click on any trace file with an
extension of trx, which will automatically launch
TraceX.
FIGURE 2.10
Refer to Chapter 5 for instructions on how to
generate trace buffers on the target using ThreadX.

TraceX Examples
A series of example trace files with the extension trx
are found in the TraceFiles subdirectory of your
installation. These pre-built examples will help you
get comfortable with using TraceX on the trace
buffers generated by ThreadX running with your
application.
One example trace file always present is the file
demo_threadx.trx. This example trace file shows
the execution of the standard ThreadX demo, as
described in Chapter 6 of the ThreadX User Guide.

Display Overview
Figure 3.1 shows the main display window of the
TraceX system analysis tool. The layout is
straightforward—the execution contexts are
represented by the vertical elements on the left side;
e.g., initialization, interrupt, idle, and the various
thread entries. The events that take place in each
context are displayed horizontally on the same
context line. For example, the QR events shown
below show that thread 2 is making successive calls
to tx_queue_receive.
FIGURE 3.1
Context changes are represented by the vertical
black lines that connect the context lines. The
currently selected event is represented by a solid red
vertical line. In this example, event 494 is selected.

Display Mode Tabs
TraceX displays system events in two different ways:
sequential and time relative. The default mode is
sequential and that is the mode shown in Figure 3.4.
User Guide
TraceX User Guide
33
Changing the mode is as simple as selecting the
Sequential View or Time View tabs in the TraceX
window. Figure 3.4 shows the Sequential View and
Time View tabs.
FIGURE 3.4
Sequential View Mode
The sequential view mode is selected by the
Sequential View tab shown in Figure 3.4. This is the
default mode. In this mode, events are shown
immediately following each other, regardless of the
elapsed time between them. Note also the ruler
above the display area in Figure 3.4. It shows the
relative event number from the beginning of the trace.
Express Logic, Inc.
34
Description of TraceX
This mode is the default mode and is useful in getting
a good overview of what is going on in the system.
Time View Mode
The time view mode is selected by the Time View
button. Figure 3.5 shows the same event trace as
Figure 3.4 except in time view mode. In this mode,
events are shown in a time relative manner, with the
solid green bar being used to show execution
between events. This mode is useful to see where
the bulk of processing is taking place in the system,
which can help developers tune their system for
greater performance and/or responsiveness.
FIGURE 3.5
User Guide
TraceX User Guide
35
Note also the ruler above the event display in Figure
3.5. This ruler shows relative ticks from the beginning
of the trace, as derived from the time stamp
instrumented in the event trace logging inside of
ThreadX. If the time stamps are too close (low
frequency timer), the events will run together.
Conversely, if the time stamps are too far apart (high
frequency timer), then the events will be too far apart.
Choosing the right frequency time stamp is an
important consideration in making the time relative
view meaningful.
System Summary Line
TraceX also provides a single summary line (the top
context in Figure 3.6) that includes all events on the
same line. This makes it easy to see an overview of a
complex system. The summary bar is especially
beneficial in systems that have many threads.
Without such a summary line, you would have to
Express Logic, Inc.
36
Description of TraceX
follow complex system interactions using the vertical
scroll bar to follow the context of execution.
FIGURE 3.6
The summary line contains a summary of the context
as well as the corresponding event summary
underneath. In the example shown in Figure 3.6, it is
easy to see that thread 2 is executing and
interrupted. The interrupt results in preemption by
thread 3, thread 6, thread 4, and thread 7, after
which thread 2 resumes execution.
System Contexts
TraceX lists the system contexts on the left-hand side
of the display, as shown in Figure 3.7. Events that
occur in a particular context are displayed on the
horizontal line to the right of that context. In this way,
you can easily ascertain which context the event
User Guide
TraceX User Guide
37
occurred as well as follow that context line to see all
the events that occurred in a particular context.
The first two context entries are always the Interrupt
and Initialize/Idle contexts. Interrupt context
represents all system events made from Interrupt
Service Routines (ISRs). Initialize/Idle context
represents two contexts in ThreadX. Events that
occur during tx_application_define, are Initialize
events and are displayed on the Initialize/Idle
context. If the system is idle and thus no events are
occurring, the green bar representing Running in the
time view is drawn on the Initialize/Idle context.
FIGURE 3.7
In the example in Figure 3.7, there are nine thread
contexts, starting from the System Timer Thread
context. Additional information about an individual
context is available by placing the mouse on that
context. The additional information includes the
thread’s starting stack address, ending stack

Description of TraceX
address, total size, percent used, relative execution
percentage, number of suspension, resumptions,
and its highest and lowest priority during the trace.
Figure 3.8 shows information for thread 0.
FIGURE 3.8
Contexts may also be moved to group those of
greater interest. This is accomplished by dragging
and dropping the context or right-clicking on the
context. Right-clicking on the context yields a dialog

for moving the context to the top or the bottom.
Figure 3.9 shows the reorder dialog for thread 3.
FIGURE 3.9
Express Logic, Inc.
40
Description of TraceX
Selecting Move to top results in the thread 3 context
being moved to the top of the context list, as shown
in Figure 3.10.
FIGURE 3.10
Thread Status Information
When enabled, TraceX displays the status of each
thread via a colored line on the thread’s context. A
green line indicates that the thread is in a “ready”
state, while a line of any other color indicates the
thread is suspended. For suspended threads, the
color of the line indicates the type of ThreadX object
that the thread is suspended on. For example, in
Figure 3.11 the green line on the System Timer
Thread’s context starting at event 496 shows that the
System Timer Thread is ready. Prior to event 496
and after event 502, the absence of the green line
User Guide
TraceX User Guide
41
indicates that the System Timer Thread is
suspended.
FIGURE 3.11
There are three modes of thread status display,
available via the Options -> Status Lines menu as
shown in Figure 3.12. The Ready Only option only
shows the ready (green) status lines, but does not
display any suspension status lines. This is the
default option for TraceX. The All On option enables
the display of all status lines (ready and suspension).
Express Logic, Inc.

Finally, the All Off option disables the display of all
status lines.
FIGURE 3.12
Event Information Display
TraceX provides detailed information on some 600
run-time events, including ThreadX, FileX, NetX,
NetX Duo, and USBX API calls and internal events.
TraceX also supports up to an additional 61,439
unique user-defined events.
Regardless of whether sequential or time display
mode is selected, a mouse-over on any event in the
display area results in detailed event information
displayed near the event. The mouse-over of event

494 in the demonstration demo_threadx.trx trace
file is shown in Figure 3.13:
FIGURE 3.13
Each event displayed contains standard information
about Context and both the Relative Time and Time
Stamp. The Context field shows what context the
event took place in. There are exactly four contexts:
thread, idle, ISR, and initialization. When an event
takes place in a thread context, the thread name and
its priority at that time is gathered and displayed as
shown above. The Relative Time shows the relative
number of timer ticks from the beginning of the trace.
The Raw Time Stamp displays the raw time source
of the event. Finally, all event-specific information is
displayed. This information is detailed throughout the
remainder of this chapter.
Express Logic, Inc.
44
Description of TraceX
Detailed event information is also available by double
clicking on any event. Double clicking on event 494 is
shown in Figure 3.14:
FIGURE 3.14
Being able to view multiple events at once gives the
user a much richer view of what happened. Seeing
them side by side is quite useful since many events
are interrelated. This is accomplished by doubleclicking on multiple events.
Current Event Display
TraceX displays the current event—in a separate
window—when selected by the user via View ->
Current Event or clicking on the current event button
on the toolbar, as shown in Figure 3.15. After
selected, TraceX displays the currently selected

event in a stand-alone window and refreshes this
window whenever another event is selected. For
example, Figure 3.16 shows the contents for
currently selected event 494.
FIGURE 3.15
FIGURE 3.16
Express Logic, Inc.
46
Description of TraceX
Event Searching
TraceX provides an extensive event search
capability. The event ID and information fields of
each event are the primary search parameters. Not
specifying a value for a search parameter indicates
that parameter effectively removes that parameter
from of the search. In addition, the search can be
done such that any parameter found will satisfy the
search or all parameters must be found to satisfy the
search. The search may also be restricted to a
particular context or cover all contexts in the trace.
Invoking the event search is done by selecting the
Search by Value button on the toolbar, as shown in
Figure 3.17. When selected the search dialog is
displayed, which specifies all the parameters for the
search. The Next and Previous buttons in the
search dialog can then be used to find the next and
previous events that match the specified search
criteria. Figure 3.18 shows the search dialog.

47
FIGURE 3.18
Zooming In and Out
By default, TraceX displays the events at their full
size. You may zoom in or zoom out as desired.
Zooming out is useful to see the overall events
captured in the trace, while zooming in is useful in
conditions where the events overlap because of the
resolution of the time stamp source. Figure 3.19
Express Logic, Inc.
48
Description of TraceX
shows the demo_threadx.trx file zoomed out so that
100% of the trace file is shown.
FIGURE 3.19
When zoomed out at 100% to show the entire trace
within the current display page, it is easy to see all
the context execution captured in the trace as well as
the general events occurring within those contexts.
Notice in Figure 3.12 that thread 1 and thread 2
execute most often. The blue coloring for their events
also suggests that these threads are making queue
service calls (queue events are blue in color).
Restoring to a full icon view is equally easy; Either
the zoom-in button may be selected repeatedly or
some factor of 100 may be entered.

Delta Ticks Between Events
Determining the number of ticks between various
events in TraceX is easy—click on the starting event
and drag the mouse to the ending event. The delta
number of ticks between the events shows up in the
upper right-hand corner of the display, as shown in
Figure 3.20.
FIGURE 3.20
The delta ticks shown in Figure 3.20 show that 501
ticks have elapsed between event 494 and event
496. This could also be calculated manually by
looking at the relative time stamps in each event and
subtracting, but using the GUI is easy and
instantaneous.

Description of TraceX
Actual Time Display
When enabled, TraceX displays the actual time in
microseconds in Time View and for the various delta
time information displayed by TraceX. By default, the
actual time display is disabled. To enable the actual
time display, the number of ticks per microsecond
must be entered via the Options -> Ticks per
Microsecond menu selection (the value to enter is
determined by the hardware timer source used for
the TraceX event logging on the target). Figure 3.21
shows a selection of 80 ticks per microsecond. After
this selection, the TraceX tick information is also
translated into microseconds, as shown in Figure
3.22.

Priority Inversions
TraceX automatically displays priority inversions
detected in the trace file. Priority inversions are
defined as conditions where a higher-priority thread
is blocked trying to obtain a mutex that is currently
owned by a lower-priority thread. This condition is
termed deterministic, because the system was set up
to operate in this manner. To inform the user, TraceX
shows deterministic priority inversion ranges as a
light salmon color.
TraceX also displays non-deterministic priority
inversions. These priority inversions differ from the
deterministic priority inversions in that another thread
of a different priority level has executed in the middle
of what was a deterministic priority inversion, thereby
Express Logic, Inc.
52
Description of TraceX
making the time within the priority inversion
somewhat non-deterministic. This condition is often
unknown to the user and can be very serious. In
order to alert the user of this condition, TraceX shows
non-deterministic priority inversions as a brighter
salmon color. Figure 3.23 shows both deterministic
and non-deterministic priority inversions.
FIGURE 3.23
Figure 3.15 shows a deterministic priority inversion
from event 24 through event 27. In this range, the
higher-priority thread 0 blocks on a mutex owned by
a lower-priority thread 1. At event 27, thread 1
releases the mutex and thus ends the priority
inversion.
The brighter shaded area shows a non-deterministic
priority inversion between event 34 through event 45.
What makes this non-deterministic is that while
thread 1 holds the mutex that higher-priority thread
User Guide
TraceX User Guide
53
0 is blocked on, an interrupt occurs that resumes
thread 2, which then executes and lengthens the
time the system is in priority inversion. This condition
can be quite serious and difficult to identify; however,
with TraceX it is easily identified.
TraceX Multi-Core
TraceX Multi-Core is nearly identical to the standard
TraceX, with two major additions. First, TraceX MultiCore has the ability to display ThreadX SMP trace
events on multiple cores. Second, TraceX Multi-Core
introduces a new performance analysis capability.
This new capability calculates the CPU Utilization of

each core. Figure 3.24 shows a trace the standard
ThreadX demonstration running on a ThreadX SMP
platform.
FIGURE 3.24
Especially take note of the core identification on the
left side. Each core contains the complete list of
contexts such that all activities for all cores may be
viewed together. In this example, event number 1501
shows queue receive event in Core 0, the next event
1502 shows a queue send event on Core 1.
Also note the new button for generating the CPU

ThreadX Event Trace Support
ThreadX provides built-in event trace support for all ThreadX
services, thread state changes, and user-defined events. The
ThreadX event-trace capability is primarily designed as a
post-mortem tool to analyze the last “n” activities in the
application. From this information, the developer may spot
problems and/or potential targets of optimization.
TraceX graphically displays the event trace buffer built by
ThreadX. The following describes how to build the buffer and
describes the underlying format of the buffer.
Enabling Event Trace
To enable event trace, define the time-stamp constants, build
the ThreadX library with TX_ENABLE_EVENT_TRACE
defined, and enable tracing by calling the tx_trace_enable
function.
Defining Time-Stamp Constants
The time-stamp constants are designed to provide the
developer control over the time-stamp used in the event trace
entries. The two time-stamp constants and their default
values are as follows:
#ifndef
#define
#endif
#ifndef
#define
#endif
TX_TRACE_TIME_SOURCE
TX_TRACE_TIME_SOURCE
++_tx_trace_simulated_time
TX_TRACE_TIME_MASK
TX_TRACE_TIME_MASK
0xFFFFFFFFUL
The above constants are defined in tx_port.h and create a
“fake” time-stamp that simply increments by one on each

event. The following is an example of an actual timestamp definition:
#ifndef
#define
#endif
#ifndef
#define
#endif
TX_TRACE_TIME_SOURCE
TX_TRACE_TIME_SOURCE
*((ULONG *) 0x0x13000004)
TX_TRACE_TIME_MASK
TX_TRACE_TIME_MASK
0xFFFFFFFFUL
The above constants specify a 32-bit timer that is
obtained by reading the address 0x13000004. Most
application specific time-stamps should be setup in a
similar fashion.
Express Logic, Inc.
72
Generating Trace Buffers
Exporting the Trace Buffer
TraceX needs the trace buffer in a binary, Intel HEX, or
Motorola S-Record file format on the host. The easiest way
to accomplish this is to stop the target and instruct your
debugger to dump the memory area you supplied to
tx_trace_enable function into a file on the host.
Warning: be careful not to stop the target within a trace
gathering code itself. Doing so can cause invalid trace
information. If the program is halted within ThreadX, it is
best to step over any trace insert macro before dumping
the trace buffer.
Appendix D shows how to dump the trace buffer from within
a variety of development tools.

Customer User Events
Inserting User-Defined Events
ThreadX provides the ability for developers to log their own
user-defined events, providing even more useful information
that can be viewed graphically by TraceX.
User-defined event numbers range from
TX_TRACE_USER_EVENT_START (4096) through
TX_TRACE_USER_EVENT_END (65535), inclusive. The
placement of the events in the trace buffer is done via the
tx_trace_user_event_insert, defined in Chapter 5. The
following example calls insert two user-defined events into
the current trace buffer on the target, namely user-defined
event 4096 and event 4098:
tx_trace_user_event_insert(4096, 1, 2, 3, 4);
tx_trace_user_event_insert(4098,0x100,0x200,0x300,0x400);
Default Display of User-Defined Events
By default, TraceX displays all user events with a default
user-defined Event icon as described in Chapter 6. Figure
10.1 shows the default user-defined event icon for events 202

223
and 203, which were placed in the event buffer via
the previous tx_trace_user_event_insert examples.
FIGURE 10.1
Detailed information is also available for user-defined
Events. Figure 10.2 shows the detailed event
information for event 202, which has event number
4096 and shows the specified 4 information fields.

Customer User Events
Defining Custom User-Defined Event
Icons
TraceX also provides the user the ability to create custom
user-defined event icons as well as custom information field
labels. This is achieved by adding event icon specifications
to the eltrxcustom.trxc configuration file, which is located in
the CustomEvents sub-directory in the main TraceX
installation directory. An example directory path is shown in
Figure 10.3.
FIGURE 10.3
The eltrxcustom.trxc custom event configuration file is a
simple ASCII text file containing 0 or more custom event
definitions. The format of the file is as follows:
//Comments
Start
[custom event definition(s)]
End
Each line between Start and End is used to defined a single
custom event. TraceX provides a template version of this file
with no custom events defined (nothing between the “Start”
User Guide
TraceX User Guide
225
and “End” labels). The format of a custom event definition is
as follows:
number,name, abbreviation,top_color, bottom_color,label1,lab el2,label2,label4
where:
number
Defines the user-defined event number,
between 4096 and 65535, inclusive.
name
Defines the logical name for the userdefined event.
abbreviation Defines the 2-letter user-defined event
abbreviation.
top_color
Defines the RGB value for the top-half of
the icon, which is a three digit number in
parenthesis. Some typical RGB
definitions are
BLACK =
(0,0,0)
WHITE =
(255,255,255)
RED =
(255,0,0)
GREEN =
(0,255,0)
BLUE =
(0,0,255)
YELLOW =
(255,255,0)
CYAN =
(0,255,255)
MAGENTA =
(255,0,255)
Using the RBG specification gives the
user a broad range of colors for each
user-defined icon. For more information
on RBG color definition, please see:
http://en.wikipedia.org/wiki/RGB#Digital_representations
botton_color Defines the RGB value for the bottom-
half of the icon, which is a three digit
number in parenthesis.

Example definitions for each of the two user-defined
events used in this chapter are shown in Figure 10.4.
The first definition is for event 4096 at line 5 of the
eltrxcustom.trxc file. This definition gives userdefined event 4096 the name First_User_Event,
specifies a two-letter abbreviation of FE, makes the
top portion of the icon red, the bottom portion of the
icon green, and names the information fields as
First_Info1, First_Info2, First_Info3, and
User Guide
TraceX User Guide
227
First_Info4. User-defined event 4098 is defined
similarly at line 6 of eltrxcustom.trxc.
FIGURE 10.4
Since the eltrxcustom.trxc file is read by TraceX
during initialization, TraceX must be exited and
restarted before the custom icon definitions can take
effect. Figure 10.5 shows the TraceX display of user-

defined events 202 and 203 with the custom event
icons defined in eltrxcustom.trxc.
FIGURE 10.5
The additional information in the custom event
definition is shown when the event is selected via a
double-click, mouse-over, or selection of the current
event button. Figure 10.6 shows the double-click
selection on event 202. Note that the event name

Format of Event Trace Buffer
ThreadX provides built-in event trace support for all
ThreadX services, thread state changes, and userdefined events. To use event trace, simply build the
ThreadX, NetX, and FileX libraries with
TX_ENABLE_EVENT_TRACE defined and enable
tracing by calling the tx_trace_enable function. This
chapter describes that process.

Format of Event Trace Buffer
Event Trace Format
The format of the ThreadX event trace buffer is
divided into three sections, namely the control
header, object registry, and the trace entries. The
following describes the general layout of the ThreadX
event trace buffer:
Control Header
Object Registry Entry 0
…
Object Register Entry “n”
Event Trace Entry 0
…
Event Trace Entry “n”
Event Trace Control Header
The control header defines the exact layout of the
event trace buffer. This includes how many ThreadX
objects can be registered as well as how many
events can be recorded. In addition, the control
header defines where each of the elements of the
User Guide
TraceX User Guide
233
trace buffer resides. The following data structure
defines the control header:
typedef struct TX_TRACE_CONTROL_HEADER_STRUCT
{
ULONG
tx_trace_control_header_id;
ULONG
tx_trace_control_header_timer_valid_ mask;
ULONG
tx_trace_control_header_trace_base_a ddress;
ULONG
tx_trace_control_header_object_regis try_start_pointer;
USHORT
tx_trace_control_header_reserved1;
USHORT
tx_trace_control_header_object_regis try_name_size;
ULONG
tx_trace_control_header_object_regis try_end_pointer;
ULONG
tx_trace_control_header_buffer_start _pointer;
ULONG
tx_trace_control_header_buffer_end_p ointer;
ULONG
tx_trace_control_header_buffer_curre nt_pointer;
ULONG
tx_trace_control_header_reserved2;
ULONG
tx_trace_control_header_reserved3;
ULONG
tx_trace_control_header_reserved4;
} TX_TRACE_CONTROL_HEADER;
Control Header ID
The control header ID consists of the 32-bit HEX value
of 0x54585442, which corresponds to the ASCII
characters TXTB. Since this value is written as a 32-bit
unsigned variable, it can also be used to detect the
endianness of the event trace buffer. For example, if the
value in the first four byes of memory is 0x54, 0x58,
0x54, 0x42, the event trace buffer was written in big
endian format. Otherwise, the event trace buffer was
written in little endian format.
Timer Valid Mask
The timer valid mask defines how many bits of the timestamp in the actual event trace entries are valid. For
example, if the time-stamp source has 16-bits, the value
in this field should be 0xFFFF. A 32-bit time-stamp
source would have a value of 0xFFFFFFFF. This value
is defined by the TX_TRACE_TIME_MASK constant in
tx_port.h.
Express Logic, Inc.
234
Format of Event Trace Buffer
Trace Base
Address
The trace buffer base address is the address the
application specified as the start of the trace buffer in
the tx_trace_enable call. This address is maintained
for the sole use of the analysis tool to derive bufferrelative offsets for the various elements in the buffer.
For example, the buffer relative offset of the current
event in the trace buffer is calculated by simple
subtraction of the base address from the current
event address.
Registry Start and
End Pointers
The registry start pointer points to the address of the
first object registry entry, while the registry end
pointer points to the address immediately following
the last register entry. These values are setup during
the tx_trace_enable processing and are not changed
throughout the duration of tracing.
Registry Name
Size
The registry name size defines maximum size in
bytes for each object name in the registry entry and
is defined by the symbol
TX_TRACE_OBJECT_REGISTRY_NAME. The
default value is 32 and is defined in tx_trace.h. The
object name corresponds to the name given by the
application when the object was created. For
example, the object registry name for a thread is the
name supplied by the application to the
tx_thread_create call.
Buffer Start and
End Pointers
The event trace buffer start pointer points to the
address of the first trace entry, while the registry end
pointer points to the address immediately following
the last trace entry. These values are setup during
the tx_trace_enable processing and are not
changed throughout the duration of tracing.
User Guide
TraceX User Guide
Current Buffer
Pointer
235
The event trace buffer current pointer points to the
address of the oldest trace entry. Since the trace
entries are maintained in a circular list, the current
buffer pointer is also represents the next trace entry
to be written.
Event Trace Object Registry
The event trace object registry contains n object
registry entries that correspond to the objects created
by the application. The main purpose of the object
registry is for external analysis tools to correlate
actual object names with the object addresses of the
trace buffer entries. The number of registry entries is
specified by the application in the tx_trace_enable
call.
Each object register entry contains information about
a specific ThreadX object previously created by the
application. The following data structure defines each
object registry entry:
typedef struct TX_TRACE_OBJE CT_REGISTRY_ENTRY_STRUCT
{
UCHAR
UCHAR
UCHAR
UCHAR
ULONG
ULONG
ULONG
UCHAR
tx_trace_obje ct_registry_entry_object_available;

tx_trace_obje ct_registry_entry_object_parameter_1;
tx_trace_obje ct_registry_entry_object_parameter_2;
tx_trace_thre ad_registry_entry_object_name
[TX_TRACE_OBJECT_REGISTRY_NAME];
} TX_TRACE_O BJECT_REGISTRY_ENTRY;
Object Available
Flag
The object available flag is set to 1 if the object
registry entry is available. Otherwise, if the value is
not 1, the object registry entry is not available. Note
Express Logic, Inc.
236
Format of Event Trace Buffer
that the entry could still contain valid information
even though it is available.
Object Entry Type
The object entry type identifies the type of object in
this entry. The following is a list of the valid object
types:

Object Reserved
Fields
For all objects other than threads, these reserved
fields should be 0. For threads, the priority of the
thread at the time it is entered into the registry is
placed in these two reserved fields.
Object Parameters
The object parameters contain supplemental
information about the object. The following describes
the supplemental information for each ThreadX
object:

Object Name
The object name contains the name of the ThreadX
object. The name is the name provided to ThreadX at
the time the object was created. By default, the object

Format of Event Trace Buffer
name has a maximum of 32 characters. Actual
names greater than 32 characters are truncated.
Event Trace Entries
The event trace entries are found in the bottom
portion of the event trace buffer. The entries are
maintained in a circular list, with the current entry
pointer pointing to the oldest entry. The number of
entries in the list is calculated by the
tx_trace_enable call.
Each object register entry contains information about
a specific ThreadX trace event. The following data
structure defines each trace event entry:

{

tx_trace_buffer_entry_informati on_field_2;
tx_trace_buffer_entry_informati on_field_3;
tx_trace_buffer_entry_informati on_field_4;
} TX_TRACE_BUFFER_ENTRY;
Thread Pointer
The thread pointer contains the address of the thread
running at the time of this event. If the event occurred
during initialization (no thread running), the value of
this pointer is 0xF0F0F0F0. If the event occurred
during an Interrupt Service Routine (ISR), the value
of this pointer is 0xFFFFFFFF. If the entry has not yet
been used, the value of this pointer is 0.
User Guide
TraceX User Guide
239
Thread Priority
The thread priority field contains the thread priority
and preemption-threshold of the thread that was
running at the time of this event. If an interrupt
context is present (thread pointer is 0xFFFFFFFF),
the value of this field is not the priority but instead the
value of _tx_thread_current_ptr at the time of the
event. Otherwise, the value of this field is 0.
Event ID
The event ID specifies the event that took place.
Valid ThreadX trace event IDs range from 1 through
1024. Values starting at 1025 and above are
reserved for user-specific events. Please refer to the
tx_trace.h file for the complete definition of ThreadX
event IDs.
Information Fields
(1-4)
The information fields contain additional information
about the specific event. Please refer to the
tx_trace.h file for the complete description of the
information fields for each of the defined ThreadX
event IDs.

Description
This 4-byte field contains the ThreadX Trace
Identification. If the trace buffer is valid, the
contents are 0x54585442 (TXTB). Since it is written as
a 32-bit unsigned word, this value is also used to
determine if the event trace information is in
little or big endian format.
Mask of valid bits in the 32-bit time stamp. This
enables use of 32, 24, 16, or event 8-bit timers.
If the time source is 32-bits, the mask is
0xFFFFFFFF. If the time source is 16-bits, the
mask is 0x0000FFFF.
The base address for all trace pointer. Subtracting
the pointer and this address will yield the proper
offset into the trace buffer.

Pointer to the start of the Trace Buffer Area
Pointer to the end of the Trace Buffer Area
Pointer to the oldest entry in the Trace Buffer.
This entry will be overwritten on the next event and
incremented to the next event (wrapping to the top
if the buffer end pointer is exceeded).

Description
This 4-byte field contains the pointer to the

If this field is NULL, the entry hasn't been used
yet. If this field is 0xFFFFFFFF, the event occurred
from within an ISR. If this entry is 0xF0F0F0F0, the
event occurred during initialization.
This 4-byte field contains the current thread pointer for interrupt
events or the thread preemption-threshold/priority for thread events.
This 4-byte field contains the Event ID of the event. A value of
0xFFFFFFFF indicates the event is invalid. All events are marked
as invalid during initialization.
This 4-byte field contains the time stamp of the event.
This 4-byte field contains the first 4-bytes of information
specific to the event.
This 4-byte field contains the second 4-bytes of information
specific to the event.
This 4-byte field contains the third 4-bytes of information

Command Line Definitions
ea2tracex.exe
Converts the trace file
generated by ThreadX in
association with the GHS tools
to the TraceX trace file format.
> ea2tracex
original_file
converted_file <cr>
Note: ThreadX for GHS tools
produces a different trace
format than ThreadX for nonGHS tools, which is why this
conversion utility is needed.
hex2tracex.exe
Converts a trace file generated
by ThreadX but dumped from
the development tool in Intel
HEX format to the binary
TraceX trace file format. Note
that TraceX V5 and above can
open HEX files without
converting them.
> hex2tracex hex_file
converted_file <cr>
mot2tracex.exe
Converts a trace file generated
by ThreadX but dumped from
the development tool in
Motorola S-Record format to
the binary TraceX trace file
format. Note that TraceX V5
and above can open S-Record
files without converting them.

Dumping the Trace Buffer
Dumping the trace buffer created by ThreadX to a file on
the host computer is done via commands and/or utilities
provided by the specific development tool being used.
This appendix contains examples of dumping a trace
buffer to a host file in some of the more popular
development tools used with ThreadX.

BenchX Tools
The trace buffer can be dumped to a host file easily
with the BenchX tools by selecting the Store
Memory To File button within the Memory View, as
shown below:
At this point, specify the trace buffer address, size,
destination file name (including path), and select the
Save button as shown below. This will create the
binary trace file for viewing within TraceX.
User Guide
TraceX User Guide
259
RealView Tools
The trace buffer can be dumped to a host file easily with
the ARM RealView tools by entering the following
command at the command line prompt in RealView:
> WRITEFILE,raw trace_file.trx=0x6860..0xE560
Upon completion, the file trace_file.trx will contain the
trace buffer that is located starting at the address
0x6860 and goes up to address 0xE560. This file is
ready for viewing by TraceX.
IAR Tools
The trace buffer can be dumped to a host file very easily
with the IAR tools by simply right clicking in the memory
view and selecting the Memory Save… option, as
shown below.
Express Logic, Inc.
260
This results in the Memory Save dialog to be
displayed. Enter the starting and ending address and
the trace file name, then select the Save button. In
the example shown below, the IAR tools save the
specified trace buffer into Intel HEX records in the file
trace_file.hex.
At this point, we have the trace buffer saved in the
trace_file.hex file on the host and is ready for
viewing with TraceX.
CodeWarrior Tools
The trace buffer can be dumped to a host file easily
with the CodeWarrior tools by entering the save
command in the Command Window. The following
example save command assumes the trace buffer
starts at 0x102200 and ends at 0x109F00:
> save –b p:0x102200..0x109F00 trace_file.trx -a 32bit
User Guide
TraceX User Guide
261
This results in the trace buffer being saved in the file
trace_file.trx on the host.
MPLAB Tools
MPLAB can create a TraceX-compatible trace file
through its Export Table utility, which allows the
export of any range of memory to a host file. To use
this utility to create a trace file for TraceX, proceed as
follows:
Step 1
Open a memory window by selecting View 
Memory.
Express Logic, Inc.
262
Step 2
Right-click within the Memory View to display a list
of options. Specify Display Format -> 1 Byte to
select byte display..
User Guide
TraceX User Guide
Step 3
263
Right-click again within the Memory View Window
and select Go To, which opens a dialog box that
enables you to specify the address of the event
buffer. This example shows event_buffer being
displayed.

Step 4
265
This highlights the contents of the first location of the
trace buffer, which is always the string BTXT….
Express Logic, Inc.
266
Step 5
Now, right-click again to bring up the options menu,
and select Export Table.
Step 6
This brings up the Export Table dialog, as shown.
Specify the range of addresses to export. For an 8K
trace buffer, as is the case in this example, specify
the range 0xA00006AC to 0xA00026AC, and enter a

name for the host file to be created
(demo_threadx.trx in this example).
Step 7
A file named demo_threadx.trx will be created on
the host, and this file can be opened by TraceX.
GHS Tools
The trace buffer can be dumped to a host file easily
with the GHS tools by entering the following
command at the command line prompt in the debug
command window:
memdump raw c:\release\threadx\demo_threadx.trx event_buffer 32768
Upon completion, the file demo_threadx.trx will
contain the trace buffer that is located in the
event_buffer with a size of 32,768 bytes and is ready
for viewing by TraceX.
Express Logic, Inc.

Renesas HEW
The trace buffer can be dumped to a host file easily
with the Renasas HEW tools by following the three
steps (and sub-steps) below:
Step 1
Open Memory Window.
