ESD Precaution
Please note that the LPC2478 OEM Board and QVGA Base Board come without
any case/box and all components are exposed for finger touches – and therefore
extra attention must be paid to ESD (electrostatic discharge) precaution.
Make it a habit always to first touch the metal surface of one of the USB or
Ethernet connectors for a few seconds with both hands before touching
any other parts of the boards. That way, you will have the same potential as
the board and therefore minimize the risk for ESD.
Never touch directly on the LPC2478 OEM Board and in general as little as possible on the QVGA
Base Board. The push-buttons on the QVGA Base Board have grounded shields to minimize the effect
of ESD.
Note that Embedded Artists does not replace boards that have been damaged by ESD.
2.3
General Handling Care
Handle the LPC2478 OEM Board and QVGA Base Board with care. The boards are not mounted in a
protective case/box and are not designed for rough physical handling. Connectors can ware out after
Copyright 2011 © Embedded Artists AB
LPC2478 Developer’s Kit - User’s Guide
Page 8
excessive use. The QVGA Base Board is designed for prototyping use, and not for integration into an
end-product.
Do not exercise excessive pressure on the LCD glass area. That will damage the display. Also, do not
apply pressure on the flex cables connecting the LCD/touch screen. These are relatively sensitive and
can be damaged if too much pressure is applied to them.
Note that Embedded Artists does not replace boards where the LCD has been improperly
handled.
2.4
Code Read Protection
The LPC2478 has a Code Read Protection function (specifically CRP3) that, if enabled, will make the
LPC2478 impossible to reprogram (unless the user program has implemented such functionality).
Note that Embedded Artists does not replace LPC2478 OEM boards where the LPC2478 has
CRP3 enabled. It’s the user’s responsibility to not invoke this mode by accident.
2.5
CE Assessment
The LPC2478 Developers Kit (consisting of the LPC2478 OEM Board and QVGA Base Board) is CE
marked. See separate CE Declaration of Conformity document.
The LPC2478 Developers Kit is a class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.
EMC emission test has been performed on the LPC2478 Developers Kit. Standard interfaces like
Ethernet, USB, serial have been in use. General expansion connectors where internal signals are
made available (for example processor pins) have been left unconnected. Connecting other devices to
the product via the general expansion connectors may alter EMC emission. It is the user‟s
responsibility to make sure EMC emission limits are not exceeded when connecting other devices to
the general expansion connectors of the LPC2478 Developers Kit.
Due to the nature of the LPC2478 Developers Kit – an evaluation board not for integration into an endproduct – fast transient immunity tests and conducted radio-frequency immunity tests have not been
executed. Externally connected cables are assumed to be less than 3 meters. The general expansion
connectors where internal signals are made available do not have any other ESD protection than from
the chip themselves. Observe ESD precaution.
Note that the LPC2478 OEM board is classified as a component and is hence not CE marked
separately. It can perform different functions in different integrations and it does not have a direct
function. It is therefore not in the scope of the CE Directive. An end product, where an OEM Board is
integration into, is however very likely to need CE marking.

3 LPC2478 OEM Board Design
This chapter contains information about the LPC2478 OEM Board design, both 32-bit and 16-bit
databus width. The schematic can be downloaded in pdf from the support page, and is recommended
to have printed out while reading this chapter.
3.1
LPC2478 OEM Board Schematics
3.1.1
CPU
The core part of the design is the NXP LPC2478 microcontroller. It‟s an ARM7TDMI-S CPU core with a
lot of different peripheral units and on-chip memory (512 KByte FLASH and 96 KByte SRAM). There is
also an external memory bus interface. Page 2 of the schematic contains the CPU section of the
design.
The microcontroller crystal frequency is 12.0000 MHz. This frequency has been selected in order to
allow high execution speed (the PLL can generate a 72 MHz core clock from this) as well as
generating standard clock frequencies for the CAN and USB interfaces. The on-chip UART peripheral
includes a fractional baud rate generator that allows standard baud rates to be generated with low
frequency error.
There is a 32.768 kHz crystal clock for the on-chip real-time clock peripheral unit or RTC for short. The
microcontroller can be placed in a very low power mode while the RTC operates and keeps track of
time. Power for the RTC (during these low power modes) comes from the VBAT input pin. Power is
sourced either from the +3.3V power supply or the external VBAT_IN signal (available on the
expansion connector), depending on which one have highest voltage.
3.1.2
Powering
There is no internal power supply on the board. The LPC2478 contains an internal DC/DC converter to
generate the internal 1.8V power needed by the core. The LPC2478 OEM Board module must be
powered by a single, external +3.3V power supply. The supply must be stable and should have at least
four 22uF bulk capacitor(s) close to the power pins on the expansion connectors.
3.1.3
Analog Inputs/Outputs
The LPC2478 contains analog peripherals that need a reference voltage, which is supplied from the
VREF input pin. This reference voltage must be supplied externally can be the VDDA power (which is
a filtered +3.3V power supply). The VDDA power is available on the expansion connector under the
name V3A. See schematic for details. A filtered version of analog ground is also available under the
name VSSA.
3.1.4
Ethernet Interface
The LPC2478 have an internal Ethernet MAC peripheral with interface to an external PHY (i.e., the
analog interface to an Ethernet interface). Page 2 of the schematic contains the Ethernet PHY. The
DP83848 external Ethernet PHY from National is used and interfaces the LPC2478 via the RMII
interface.
The PHY is driven by an external 50 MHz clock that is also feed to the LPC2478. This is part of the
RMII interface specification.
The PHY is always enables (can be disabled under program control) but have an external „power
down‟ signal that can be used by an external device. There is also an interrupt signal from the PHY
that can be used to signal link events (like connect/disconnect of a cable). Neither the power down nor
the interrupt signal is used by the LPC2478 OEM Board but the signals are available on the expansion
connector. If the signals are not used, just leave them unconnected.

3.1.5
Page 11
External Memories
There are three external memory chips connected to the external memory bus interface of the
LPC2478. Both 32-bit and 16-bit databus width versions of the board exist.

An external NOR FLASH (32 MBit = 4 MByte in size) addressed by CS0 (address range:
0x8000 0000 – 0x80FF FFFF). Accessed via 16-bit databus.

An external NAND FLASH (1 GBit = 128 MByte in size) addressed by CS1 (address range:
0x8100 0000 – 0x81FF FFFF). Accessed via 8-bit databus.

An external SDRAM (256 MBit = 32 MByte in size) addressed by DYCS0 (address range:
0xA000 0000 – 0xAFFF FFFF). Accessed via 32-bit or 16-bit databus, dependent on board
version.
The NAND FLASH has an optional busy output that can be used for controlling the erase/program
operations with better precision. The signal is available on the expansion connector. If needed the
signal can be routed to a suitable (i.e., free) input pin. The busy status of the chip is also available
under software control.
3.1.6
External Memory Interface
The LPC2478 memory interface is available on the expansion connector. The data bus width is either
16- or 32-bits on the external interface (depending on board version). All signals are buffered. The
buffers are disabled unless enabled by external signals.
By pulling signal ABUF_EN low, the two buffers for address and control signals are enabled and act as
outputs (from the LPC2478 OEM Board).
The data bus buffer is controlled by the signal DBUS_EN. By pulling this signal low, the data bus buffer
is enabled. The LPC2478 signal OE controls the direction of the data bus buffer. During read
operations the buffer acts as an input and during write operations it acts as an output.
Note that DBUS_EN must not be pulled low constantly. In that case the buffer will collide with the
board‟s internal data bus. DBUS_EN must only be pulled low when an external memory/IO device is
accessed. If, for example, CS2 is used to decode and access an external device, connect the signal
CS2 directly to DBUS_EN.
If more than one chip select signal is used, (logically) AND all chip select signal together before driving
the DBUS_EN signal.
If the external memory interface is not used, leave ABUS_EN and DBUS_EN unconnected.
3.1.7
Reset Generation
The rest generation is handled by a standard voltage supervisor chip, CAT811S from Catalyst
Semiconductor. The reset signal will be held active (i.e., low) until the supply voltages, +3.3V, is within
margins. The reset duration is typically 200 mS (consult the CAT811S datasheet for exact details). The
output reset signal is push/pull output that is converted to an open-collector / open-drain output via the
74LVC1G125 buffer. An external reset source can pull the reset signal low (with an opencollector/open-drain output).
The reset generator can be found on page 2 of the schematic.
3.1.8
I2C E2PROM
There is also a 256 kbit E2PROM accessible via the I2C interface. The LPC2478 microcontroller has
three on-chip I2C communication channels. Channel #0 is used for communicating with the E2PROM.
More peripheral units are easily connected to the two-wire I2C bus, just as long as the addresses do
not collide. The address of the 256kbit E2PROM is 0xA0.
There are 1.5 kohm pull-up resistors (which are always needed on I2C busses) included on the board.
The I2C E2PROM can be found on page 2 of the schematic.

3.1.9
Page 12
Expansion Connectors
The LPC2478 OEM Board integrated the core part of a typical LPC2478 board design with a
reasonable large amount of external memories. Almost all signals of LPC2478 are available on the 200
pos, 0.6mm pitch expansion connector (SODIMM-200 format).
3.2
Memory Layout
The external memory controller on the LPC2478 defines eight memory regions, named: CS0, CS1,
CS2, CS3, DYCS0, DYCS1, DYCS2, and DYCS3. Of these eight, three memory areas are used by the
LPC2478 OEM Board. These are:

CS0 (address range: 0x8000 0000 – 0x80FF FFFF)
An external NOR FLASH (32 MBit = 4 MByte in size) is addressed.

CS1 (address range: 0x8100 0000 – 0x81FF FFFF)
An external NAND FLASH (1 GBit = 128 MByte in size) is addressed.

DYCS0 (address range: 0xA000 0000 – 0xAFFF FFFF)
An external SDRAM (256 MBit = 32 MByte in size) is addressed.
These three memory regions cannot be used by external devices. CS2 and DYCS1 are however free
for external use via the buffered memory interface. Both address and data busses are buffered.
3.3
Usage of CPU Pins
Almost all pins of the LPC2478 are directly available on the expansion connectors. Only in a few cases
are pins used for dedicated functionality like Ethernet interface and chip select signals. Such pins are
not available on the expansion connector. The table below lists all pins and their possible restrictions.

LPC2478 OEM Board Mechanical Dimensions and Connector
Figure 1 below contains a drawing of the board that includes mechanical measures. See SODIMM-200
standard for exact measures. 1.8V keying is used (SODIMM-200 boards are either 1.8V or 2.5V
keyed).

The SODIMM-200 format is a standard and there exist many connectors that are suitable form many
different manufactures. The many sources also keep the connector cost very low. Note that the
connector should be 1.8V keyed.

One suitable connector is 0-1473005-4 from Tyco/AMP. Basically any SODIMM, DDR2, 200pos, 1.8V,
right angled connector will do.
3.5
Known Limitation of LPC2478 OEM Board
3.5.1
Ver 1.0 – SDRAM Clock Frequency
There is one known limitation of the LPC2478 OEM Board. The cpu core clock frequency must not
exceed 48 MHz when using the external SDRAM. This limitation only applies to v1.0 boards with 32-bit
external databus width. Boards with 16-bit databus can run at full speed. On v1.0 of 16-bit boards there
is a small modification on the boards. On all v1.1 boards (16- and 32-bit) this limitation is fixed in the
design, i.e., the boards can run at full 72MHz.
Normally the internal PLL frequency is set to 288 MHz (the external 12 MHz crystal frequency
multiplied by 24). Dividing 288 MHz with 6 gives a core frequency of 48 MHz and dividing with 4 gives
72 MHz.
The limitation results in a maximum cpu clock frequency of 48 MHz when using the external SDRAM. If
the SDRAM is not used, the cpu core frequency can be up to full specification of the LPC2478.
3.5.2
Ver 1.0 – Ethernet Clock
Due to an error in clock routing between the Ethernet PHY and the LPC2478, rev 1.0 boards have
been modified slightly. The error is also temperature dependent. Only a small number of ver 1.0
boards have been shipped without this modification and these boards were tested not to have any
problems. The picture below illustrates the modification made.
The problem is fixed on ver 1.1 boards.
1) Pin 25 of the Ethernet PHY has been lifted
and removed.
2) A short wire has been soldered to the 50
MHz oscillator output.
3) The wire is soldered in the other end to
the pad of the removed Ethernet PHY pin.
Figure 2 - LPC2478 OEM Board Ethernet Clock Modification
3.5.3
NAND FLASH Bad Block
The NAND Flash is the K9F1G08U0A from Samsung and contains 1G bit with a spare 32M bit
capacity. The chip may include invalid blocks when shipped from factory. A maximum of 20 invalid
blocks may exist initially, i.e., 1004-1024 valid blocks. Additional invalid blocks may develop while

being used. Invalid blocks are defined as blocks that contain one or more bad bits. Do not erase or
program factory-marked bad blocks. Refer to technical notes from Samsung for appropriate
management of invalid blocks.
3.5.4
Brand of Memory Chips
Note that there is no guarantee for a certain brand or version of memory chips; NOR flash, NAND flash
and SDRAM. The lifetime of memory chips is limited and availability can also be limited from time to
time. Embedded Artists make every effort to mount the original design chip on the board. In case that
is impossible a compatible chip will instead be mounted without any prior notice. There can be small
programming differences between mounted brands. The application program shall always read the
chip id of flash devices to make certain which chip is actually mounted on the board.
The support page contains datasheets to the different memory devices and information about mounted
devices on different board versions.

4 QVGA Base Board Design
This chapter contains information about the peripherals and general design of the QVGA Base Board
and how to set the different jumpers on the board. The schematic can be downloaded in pdf from the
support page, and is recommended to have printed out while reading this chapter.
The QVGA Base Board contains a number interfaces and connectors to the LPC2478 OEM Board.
The design can be viewed as a reference schematic for custom designs around the LPC2478 OEM
Board.
4.1
Usage of CPU Pins
Almost all pins of the LPC2478 are directly available on the expansion connectors. Only in a few cases
are pins used for dedicated functionality like Ethernet interface and chip select signals. Such pins are
not available on the expansion connector. The table below lists all pins and their possible restrictions.

Known Limitation of QVGA Base Board
4.2.1
Version 1.0/1.1 – SD/MMC Interface Pullups
Newer SD/MMC memory cards require pull-ups (10-100Kohm) on the five data and command signals.
Version 1.2 of the QVGA Base Board has these five pull-up resistors, but version 1.0 and version 1.1
do not. In case of problems with the interface, it is recommended to add pull-up resistors. See version
1.2 schematic for details.

Embedded Artists.
Figure 4 – QVGA Base Board Default Jumper Positions
4.3.2
Illegal Jumper Combinations
Note that some jumpers are mutual exclusive and should not be inserted simultaneously.

USB-OTG and LCD interface; the four jumpers in J25 should not be inserted when using the
LCD interface since signals (P1.27-P1.29) are also connected to the ISP1301.

When using the 32-bit data bus version of the LPC2478 OEM Board, all jumpers in
connectors J20 should always be removed. Also J23/J24 should not be in upper position. The
UART signals (in signals P3.xx) else collide with the upper 16 data bits of the data bus.
J23/J24 can be in lower position to connect UART#2 (RxD/TxD) to the RS232 interface.

the capabilities of the processor and Embedded Artists as a software provider. See our
sample application package for sample source code, which can be downloaded from our
support page.
5.1.1
Custom Slideshow Demo Application #3
It‟s possible to create own slide shows with demo application #3. The pictures are stored on a
MMC/SD memory card, inserted in the MMC/SD memory card connector on the QVGA Base
Board.
The slideshow is defined in a text files with a specific format, as described below. The file
should be named: custom.txt and be placed in a folder named /romfs_override/slideshow/
on the memory card.
The /romfs_override/ part of the path will be ignored by the demo application and the
contents of the folder will be considered as root. E.g. /romfs_override/test/myfile.gif should
be referenced from within the slideshow file as /test/myfile.gif.
The demo application supports .bmp, .jpg and .png images. All images must be 240x320 in
size.

Initial Setup and Powering
The board can be powered from a PC via the included USB cable (mini-B to A cable). A separate
power supply is however needed in stand-alone situations or when running USB Host application
(when powering heavy load external USB devices). The power supply should be 9-15V DC, 2 Amp. A
2.1mm standard power plug is used to interface the board. Any polarity is accepted.
See Figure 7 below for locating the USB connector and/or the 2.1mm power connector.
It is possible to have both the USB cable and external powering connected to the board at the same
time.

Optional Powering
Power
Supply
USB cable
Figure 7 – Powering of QVGA Base Board
The QVGA Base Board contains an USB-to-Serial bridge chip (FT232R from FTDI) that connects
UART channel #0 on the LPC2478 to a virtual COM port on the PC (via USB). It is this serial channel
that is the console interface to system (in the uClinux system, this is the console, and in the sample
applications this is the interface where printf() ends up in).
Special USB drivers must be installed on the PC in order for the virtual COM port to be created. See
Section 5.4 for a description of how to install the FTDI USB driver.
There are four jumpers on the QVGA Base Board related to the USB serial channel, connected to
UART #0 of the LPC2478. See Figure 8 below for details about where the jumpers are located. Make
sure the 'automatic ISP' jumpers are open. If not, it's possible that a terminal program resets the board
and/or enable ISP mode by accident. These jumpers should normally always be open.

Page 28
The only exception is when downloading new code into the cpu via ISP, i.e., via the USB-to-serial
channel.
Follow the steps below to get contact with the console interface of the system:
1. Connect the USB cable between the PC and the LPC2478 OEM board.
2. Verify that the power LED on the LPC2478 OEM Board lights.
3. Search for the new (virtual) COM port that is created. This can be down from the 'Device
Manager' in Windows.
4. Make sure the settings of the new COM port is: 115200 bps or 38400 bps, 8N1 (8 databits, no
parity, 1 stopbit). 115200 bps if checking the output from the demo program and 38400 bps if
working with the uCLinux port. The COM port number should be a low number, preferably
below 6, since some terminal programs can only handle COM port number up to 5.
5. Make sure the 'automatic ISP' jumpers are open and that the RX/TX jumpers are closed as in
the picture above.
6. Start a terminal program and connect to the new COM port.
7. Press the reset button (lower left corner of the QVGA Base Board) and observe the system
console output in the terminal program window.
5.3
Getting Started with uClinux
There is a uClinux port for the board. In order to get started, the system has to be prepared for running
uClinux. The first step is to download the uBoot bootloader into the LPC2478 internal flash memory.
This can be downloaded either via ISP or via the JTAG interface. The uBoot bootloader hex file can be
downloaded from the board‟s support page.
This guide is just a quick guide you get to take the first step and start using the board. More detailed
information can be found on the board‟s support page.
5.3.1
Basic Requirements
This is a list of what you need to have before you start:

A Windows© PC with an Internet browser (e.g. Internet Explorer or Firefox), a Telnet client, a
FTP client and/or a SSH client.
(A Windows PC has Internet Explorer, a Telnet and a FTP client as default.)

A suitable terminal program.

An Ethernet cable (LAN) cable to connect the board to your PC
(a crossed cable if direct connection to the PC or a normal cable if connected to a switch or
hub).

Optionally a power supply, 9-15V DC, 2 Amp. A 2.1mm standard power plug is used. Any
polarity. Only needed if USB Host shall drive heavy external load (not needed for smaller
external USB host loads, like keyboards and memory sticks).
5.3.2
LAN/Ethernet Setup
Figure 9 below illustrates how to connect the QVGA Base Board to your PC via Ethernet. Either
directly (the red cable) or via an Ethernet switch/hub (the blue cable). The red cable is a crossed
Ethernet cable and the blue is a normal cable.
The uClinux Ethernet driver (of the LPC2478 OEM Board) can automatically detect the type of cable
and act accordingly, so different cables are not strictly needed.

Page 29
Your PC
Switch
Figure 9 – Ethernet/LAN Cable Connection
The Ethernet cable should be connected during powerup. Else there will be a long timeout delay where
the board waits for a valid Ethernet link.
The default network configuration of the LPC2478 OEM Board is:
IP address: 192.168.0.100
Netmask: 255.255.255.0
Default gateway: 192.168.0.1
Nodes on an IP network can communicate directly with each other if they are on the same LAN (i.e.,
Ethernet network) and is on the same IP subnet. This means that the LPC2478 OEM Board must be
on the same IP subnet as your PC.
An IP address starting with 192.168.0.x is a common IP subnet for many PCs. If this does not match
your PC either change the IP address of your PC or change the IP address of the LPC2478 OEM
Board (see description of this at the last section of this page).
Make sure your PC does not have the IP address 192.168.0.100, but any other IP address in the range
192.168.0.X, where X is 1-99,101-254 will do.
Some valid IP addresses for your PC are for example: 192.168.0.2, 192.168.0.3 or 192.168.0.200.
Now it's time for the first test. Connect the Ethernet cable and power up the board. Make sure the PC
and the LPC2478 OEM Board are in the same IP subnets.
An easy way to test if Ethernet/IP communication function properly is to ping the board. From a
command prompt window, type:

Note the green LEDs (on the Ethernet connector of the QVGA Base Board) that flash every time an
Ethernet frame is received. You should be able to see the LED flash at the same rate as the ping
packages are sent. Other communication on your Ethernet network might make the LED flash much
faster than this.

FTDI USB Driver Installation
A USB driver must be installed on your PC computer in order for the USB-to-UART chip (FT232R) to
function. Make sure to download the latest version of the driver, which can be found at the following
URL:
http://www.ftdichip.com/Drivers/VCP.htm
Search for a FT232R driver for your operating system. Also see FTDI‟s installation guides for details
how to install the driver for different operating systems:
http://www.ftdichip.com/Support/Documents/InstallGuides.htm
When the QVGA Base Board is connected to the PC (via an USB cable) the PC will ask for a driver.
Unpack/unzip the downloaded driver file and browse to the position of the driver files. After successful
driver installation, a COM port will be created. Before communication with the Board can take place the
UART settings must be correctly set. The following description is valid for Windows™ XP, but other
operating systems have similar dialog windows. See the USB driver documentation for details, if
needed.
To change UART settings, first open the System Properties dialog, as illustrated in the figure below.

Then select the Device Manager and then open the Ports list, as illustrated in Figure 11 below.

Ports
Figure 11 – Device Manager Dialog
The new COM port (USB Serial Port) will be listed under the Ports list. Right-click on the new USB
Serial Port and select Properties, as illustrated in Figure 12 below.

Properties
Figure 12 – Device Manager Port Dialog
Set 115200 or 38400 bits per second, 8 data bits, none parity, 1 stop bit, and none flow control, as
illustrated in Figure 13 below. (Select 115200 bps is connecting to the demo program and 38400 if
working with uClinux.) Then select Advanced settings. Please note that different application programs

can use different baudrate settings for the serial channel. Other baudrates can also be used,
depending on your specific application.

settings
Figure 13 – USB Serial Port Properties Dialog
Set the desired COM port number under the Advanced settings dialog. NXP‟s FLASH Utility program
(for ISP program download) needs, for example, a COM port number between 1 and 5. Very often the
COM port number selected but the USB Serial Port is higher than this, so this needs to be changed
manually.
It is common that all COM ports with low numbers are listed as occupied, but test to change to a low
number anyways. Very often it‟s no problem at all to do this.

Finally it‟s time to test if you have successfully installed and configured the USB Serial Port. Start a
terminal program. Connect to the correct COM port, with 38400 bits per second, 8N1, no flow control.
Remember to not have the USB-ISP jumpers inserted.

A message like below should be printed on the terminal. Please note that the picture below is just an
example of the uClinux startup console.

USB Driver Behavior
Sometimes the USB COM port does not enumerate properly when the board in connected to the PC.
This is a known “feature” of the USB driver. If you experience this problem, just unplug the board
shortly and then plug in again. A new COM port that can be accessed properly should be created the
second time.
This problem may occur after every time you start (i.e., power cycle) your PC.
If the ISP jumpers are inserted, pressing the reset button is often required in order to startup the board
(it can be placed in bootloader mode during startup due to RTS/DTR signal handling by the USB driver
during startup).
