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.
Serial Converter Pin Layouts
Cables on the serial converters are provided. You can use the 6 Pin (Fixed) to 4 Pin (Fixed) provided. The
pin layouts of the serial converters for use with the board are as follows:

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”
7. Open command prompt
8. tftp upbios.tst
9. tftp uboot.bin (please observe the DIAG LED is off)
10. If either step 9 or step 10 fail, please start from step 3 again.
11. Power off the device and unplug JTAG cable
12. Power on the device and tftp the firmware into the device.
13. Reboot when done.
BUILD AND INSTALL PROCESS
For OpenWRT firmware on uboot Loader
Minimun Requirement
1．OpenWRT will only be supported on WPJ558 with 8MB NOR flash and above.
2．Please ensure that the Ethernet connection is able to ping address = 192.168.1.1
Compiling OpenWRT on WPJ558 + ath9k with patches from Compex.
-Recommended Linux host: CentOS 6.x, Debian 6.x
-During the first build of openwrt, about 300MB of various source files
-will be downloaded from the internet.The downloaded files will be put in openwrt/dl.
