Note:
Our Serial port Implementation requires an external
high-impedance serial port not usually available
with the serial ports of the notebooks/computers.
You will need a Serial Converter available in the
market. For our customers’ convenience, it is
bundled together with the board Development Kit.
Serial Console Settings
The serial console settings used together with the serial port is given below.
This serial port uses TTL signals, and therefore you have to use serial converter using MAX-211 IC (or other
IC in the market that convert TTL signals to RS232 signals) in order to use it with the PC.

Precaution when using Serial Converter
Please attach the serial converter first on the board serial header, before attaching the power supply. This is
to ensure that there is no surge of power to the serial converter, and prevent any damage the chipset on
the serial converter.

Note:
Normally, it has a JTAG Programmer compatible with the board. It is
bundled with the board Development Kit. This JTAG programmer is
able to download file onto the Flash, and thus recover a corrupted
loader.
Ethernet Connectors
The board contains 2 X 10/100/1000 Base-T Ethernet Channels. The Ethernet Channels are available
through standard 8-pin RJ45 connectors.

JTAG PROCESS
Minimum Requirement
1. OCD Commander Ver2.5.4
2. upbios.tst file (same for all Compex device)
3. uboot.bin file
4. JTAG cable
Steps
1. Install the OCD Commander to your PC
2. Plug the JTAG cable to the JTAG port of the device
3. Run OCD Commander Program, Set "Target Processor" for the particular device, Click "OK"
4. If there is this error message “Error Response from INITIALIZE....”, please check the JTAG cable connection.
Close the OCD Commander Program and go back to Step 3.
5. Click on the “Macro” and choose a specific .mac file.
6. Let it run until u see “go”
