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

Getting started UM1509

3 Getting started

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

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.

UM1509 Configuration

4 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 Ta bl e 1.

)

Table 1. MII addresses of the Ethernet PHYs (U5 and U6)

Ethernet PHY MII address

U5 0x01

U6 0x02

By default the initial configuration of the Ethernet PHYs is selected as shown in Ta bl e 2.

Table 2. Default configuration of the Ethernet PHYs (U5 and U6)

Function Default configuration

Auto negotiation Enabled

10/100 Mbits 100 Mbits selected for auto negotiation advertisement

Half/Full duplex Full duplex selected for auto negotiation advertisement

Internal Loopback Disabled

Power down Disabled (PHY is not in Power down state)

MII/RMII mode MII selected

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

● Digital input parallel (CN5): STEVAL-IFP004V1 and STEVAL-IFP008V1

● Digital output parallel (CN6): STEVAL-IFP002V1, STEVAL-IFP001V1 and STEVAL-

IFP006V1

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.

(UART0) Default setting: Not loaded

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

board.

4.5 Power supply

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.

4.6 Temperature sensor

There is an analog temperature sensor (STLM20) available on the board that is connected
to the analog input AIN0 of the CPU board. It is possible to disconnect it by removing jumper
JP10. The jumper is loaded by default.

4.7 Potentiometer

There is a 10 kΩ potentiometer available on the board connected to the analog input AIN1
of the CPU board. It is possible to disconnect it by removing jumper JP9. The jumper is
loaded by default.

4.8 General-purpose ADC connector

Eight analog input lines are available on connector CN9. Inside the connector it is also
possible to determine the range of the conversion by setting the conversion limits on the pin
CN9-19 (lower limit) and CN9-1 (upper limit) via jumpers JP7 and JP8.

GND ≤ ADC_VREFN ≤ AIN0 -AIN7 ≤ ADC_VREFP ≤ +2.5 V ADC

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.

4.11 Reset button

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.

4.12 MicroSD card

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
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.

do not have to be registered nor are they subject to the subsequent obligations.

NO WARRANTY. The Demo Product is provided "as is" and "with all faults" without warranty of any kind expressed or

implied. ST and its licensors expressly disclaim all warranties, expressed, implied or otherwise, including without limitation,
warranties of merchantability, fitness for a particular purpose and non-infringement of intellectual property rights. ST does
not warrant that the use in whole or in part of the Demo Product will be interrupted or error free, will meet your requirements,
or will operate with the combination of hardware and software selected by You. You are responsible for determining whether

ST shall not have any liability in case of damages, losses, claims or actions anyhow caused from combination of the Demo
Product with another product, board, software or device.

ST has not authorized anyone to make any representation or warranty for the Demo Product, and any technical, applications
or design information or advice, quality characterization, reliability data or other services provided by ST shall not constitute
any representation or warranty by ST or alter this disclaimer or warranty, and in no additional obligations or liabilities shall
arise from ST's providing such information or services. ST does not assume or authorize any other person to assume for it
any other liability in connection with its Demo Products.

All other warranties, conditions or other terms implied by law are excluded to the fullest extent permitted by law.

LIMITATION OF LIABILITIES. In no event ST or its licensors shall be liable to You or any third party for any indirect, special,
consequential, incidental, punitive damages or other damages (including but not limited to, the cost of labour, re­qualification, delay, loss of profits, loss of revenues, loss of data, costs of procurement of substitute goods or services or the

SEVERABILITY. If any provision of this agreement is or becomes, at any time or for any reason, unenforceable or invalid,
no other provision of this agreement shall be affected thereby, and the remaining provisions of this agreement shall continue
with the same force and effect as if such unenforceable or invalid provisions had not been inserted in this Agreement.

WAIVER. The waiver by either party of any breach of any provisions of this Agreement shall not operate or be construed as
a waiver of any other or a subsequent breach of the same or a different provision.

RELATIONSHIP OF THE PARTIES. Nothing in this Agreement shall create, or be deemed to create, a partnership or the
relationship of principal and agent or employer and employee between the Parties. Neither Party has the authority or power
to bind, to contract in the name of or to create a liability for the other in any way or for any purpose.

RECYCLING. The Demo Product is not to be disposed as an urban waste. At the end of its life cycle, differentiated
waste collection must be followed, as stated in the directive 2002/96/EC.

In all the countries belonging to the European Union (EU Dir. 2002/96/EC) and those following differentiated recycling, the
