EVALSP320SPLC evaluation board for SPEAr320S

Introduction

This user manual describes the implementation of the EVALSP320SPLC evaluation board

(order code: EVALSP320SPLC). This evaluation board can be used to evaluate the

SPEAr320S microprocessor with a variety of devices and especially its Media Independent

Interface (MII) Automation mode.

The EVALSP320SPLC evaluation kit includes a single application board identified as "MII mode".

The SPEAr320S microprocessor is mounted on a separate CPU board, which is not included with the EVALSP320SPLC kit. It must be ordered separately with order code

EVALSP320SCPU.

The EVALSP320SCPU board must be plugged on the MII mode application board.

The MII mode application board is equipped with two Ethernet, three RS-232, one RS-485, two CAN, SPI, I²C communication interfaces and MicroSD card socket with SDIO interface.

There are also two general-purpose push-buttons, four LEDs, a temperature sensor and a potentiometer available for the user interface.

The application board also includes digital input/output serial/parallel connectors with a pinout compatible to many existing evaluation boards from ST:

Digital input serial: STEVAL-IFP007V1

Digital input parallel: STEVAL-IFP004V1 and STEVAL-IFP008V1

Digital output serial: STEVAL-IFP009V1

Digital output parallel: STEVAL-IFP002V1, STEVAL-IFP001V1 and STEVAL-IFP006V1

The application board can be powered using a standard DC power supply (7 V to 30 V DC) or directly using a 24 V DC industrial mains supply.

Doc ID 022703 Rev 2 7/36

Getting started UM1509

3.1 Unpacking

Warning: This board contains static sensitive devices.

The EVALSP320SPLC evaluation board is shipped in protective anti-static packaging. Do not submit the board to high electrostatic potentials, and follow good practices for working with static sensitive devices.

●

●

Wear an anti-static wristband . Wearing a simple anti-static wristband can help prevent ESD from damaging the board.

Zero potential . Always touch a grounded conducting material before handling the board, and periodically while handling it.

●

●

Use an anti-static mat . When configuring the board, place it on and anti-static mat to reduce the possibility of ESD damage.

Handle only the edges . Handle the board by its edges only, and avoid touching board components.

3.2 Connecting

1.

Connect a serial cable from the application board (connector CN13: RS232_0/UART0) to a host PC (see

Figure 3: Application board layout

).

2. On a host PC running Windows or Linux, start the Terminal program.

3. Connect a power supply to the EVALSP320SPLC evaluation board as described in

Section 4.5: Power supply on page 13

.

4. Power on the board. The Terminal program displays a sequence of boot messages followed by the Linux console prompt.

For more information, refer to user manual UM0844 "Getting started with Linux for SPEAr" available at www.st.com/spear .

3.3 Booting

The EVALSP320SPLC evaluation board can boot a Linux kernel pre-installed in the serial

NOR Flash.

At power on, the serial port outputs a brief header message with some uBoot information

(uBoot version, SDK version, and some internal hardware information). At this point you can choose to:

● Stop the system directly in uBoot : Press the spacebar on the host computer keyboard before the boot delay time expires (default is 3 seconds).

● Boot Linux : The system logs you in automatically as super user and the Linux shell prompt displays on the screen.

Configuration

4.1 Ethernet

There are two Ethernet PHYs (U5 and U6) available on the board that are connected through the media independent interfaces (MII) to the Ethernet MACs on the CPU board processor.

By default the MII addresses of the Ethernet PHYs are selected as shown in

Table 1 .

There are two LEDs embedded in each RJ-45 connector (CN7 and CN8) that indicate the status of the line:

● The green LED in the connector is driven on continuously when the Ethernet link is established with the counterpart.

● The yellow LED in the connector blinks when there is TX or RX activity.

The Serial Management Interface (SMI) is part of the MII interface and is used to transfer management information between the MAC and PHY (access of the PHY registers). There are two SMI interfaces coming from each Ethernet MAC. It is possible to use only one of them to control both Ethernet PHYs or each SMI can be used separately for each PHY.

For the two Ethernet PHYs (U5 and U6 in MII mode) to function correctly, it is necessary to clock them using a 25-MHz clock. There are two ways to deliver the 25-MHz clock signal to the devices.

4.2 Digital input / digital output connectors

The digital input and digital output connectors are used to extend the EVALSP320SPLC board with the industrial input and output cards.

The input sensors (for example, proximity switches) of the controlled industrial process are normally decoupled and connected by the current limiters based on the CLT and SCLT devices of the microcontroller. The digital outputs, also electrically decoupled, are based on high-side drivers which are used in industrial environments to switch industrial loads (valves, relays, …) and process control. For both the inputs and outputs, we can use either serial

(SPI) or parallel (GPIO) IN/OUT cards.

The EVALSP320SPLC board is compatible with the following cards:

●

Digital input serial (CN3): STEVAL-IFP007V1

Digital output serial (CN4): STEVAL-IFP009V1

4.4 RS-232 and RS-485 transceivers

There are three RS-232 DB9 plug connectors and one RS-485 DB9 socket connector with a

Profibus DP compliant pinout available on the board.

UART0 features the full modem control signals and fully utilizes U10, U12 and partly U14

RS-232 transceivers. The RS232_0 signals are available through the CN13 connector.

Optionally when the U10 RS-232 transceiver is not soldered on the board, it is possible to line in RS232_TXD and RS232_RXD signals from the CPU board to the CN13 connector.

UART1 features only RX/TX functionality and is connected to the U14 RS-232 transceiver which RS232_1 signals are then available from the CN15 connector.

UART2 features only RX/TX functionality and uses U13 RS232 transceiver which RS232_2 signals are available from the CN14 connector. Optionally by setting jumpers JP12 and

JP13, the UART2 RX/TX lines can be connected to the RS-485 transceiver U11 whose outputs are then available from connectors CN11 and CN12. The RS-485 transceiver U11 can be controlled through GPIO pins PL_GPIO77 (receiver enable, R70 - pull up) and

PL_GPIO78 (driver output enable, R73 pull down). Check the ST3485 datasheet for further details about all possible transceiver configurations.

Caution: Do not fit the jumpers when the U10 RS-232 transceiver is soldered on the evaluation board.

There are two options to supply the EVALSP320SPLC evaluation board:

1.

Connecting the +5 V voltage adapter (delivered in the EVALSP320SPLC package) to the J11 power voltage connector on the CPU board.

2. Connecting a 7 V to 30 V DC power source (not included in the EVALSP320SPLC package) to either connectors CN17 or CN18 on the application board.

The input voltage is connected to the DC/DC converter U16 (L7986A or optionally L5973A).

The board is protected against overvoltages by the D4 transil diode (SM6T33A) and against possible reverse polarity voltage from an incorrect power plug-in by the D3 Schottky diode

(STPS3L40U).

Warning: Do not use both Power supply options at the same time.

Doing this may destroy the boards.

4.9 General-purpose buttons (B1 and B2)

There are two general-purpose buttons (B1 and B2) available on the top side of the board.

Button B1 can be disconnected from the input CPU board by soldering out resistor R56 and button B2 by soldering out resistor R61.

4.10 LEDs

There are 4 general-purpose LEDs (LD1-LD4) available on the top side of the board. All

LEDs are driven on when the related GPIO pin is driven high.

Configuration UM1509

A manual reset button (B3) is available on the board's top side. It resets the microprocessor on the core board. It can be disconnected from the input reset signal of the core board by soldering out resistor R65. In order to perform a hardware reset of the first Ethernet PHY U5

(ETH1), it is necessary to drive low pin PL_GPIO66 of the microprocessor. In order to perform a hardware reset of the second Ethernet PHY U6 (ETH2), it is necessary to drive low pin PL_GPIO76 of the microprocessor.

The MicroSD card connector connected to the SDIO interface of the EVALSP320SPLC is available on the board. MicroSD card detection is managed by the standard SDIO signal

SDCD when the card is inserted. In order to power-up the MicroSD card properly, it is necessary to detect the card insertion and then to enable the single channel power switch

U15 by means of PL_GPIO61 (active low).

Using the thermal and short-circuit protection of the power switch, it is possible to detect overcurrent conditions (> 500 mA) on the MicroSD card connector by pin PL_GPIO57 which is connected to the overcurrent pin of U15. By default the U15 power output is disabled by the R83 pull-up resistor connected to the Enable pin of the power switch.
