To load OpenWRT you are not required to use JTAG as Compex Myloader V2.40 or above is already support OpenWRT
So what you need to do is to Check whether your loader version is Compex Loader V 2.40 (Now should be V2.43 that already able to Support kamiakze 7.09 ) at 22 July 2007
So if Already V2.4x then you may load you firmware by using TFTP .
If not please provide you serial plus all information needed to the Support or you will need to waste your time for this info again.
HOW IF YOU DON HV SERIAL CONSOLE ? (Take it easy)
1. Go to the loader/firmware mode
[Press and hold the reset button then power on, the diag led will blinking]
2. then go to the same directory then do the tftp
[TFTP -i 192.168.168.1 firmware.bin]
[192.168.168.1 is default frimware mode IP]
3. Wait
[The dig led will steady on now. Wait for 1 Min the diag led will blinking again]
[If your diag led never steadly on mean the firmware is not loaded to the device then you may try it again]
4. After blinking, you may restart your device.
Now check ur IP and set to 192.168.1.2-254 [192.168.1.1 = default ip]
Telnet to 192.168.1.1
Done if you see OpenWRT logo.
If not but a serial console to see what is going on.
END

JTAG is only needed when your loader is corrupted, as long as loader able to boot up serial console is sufficient enough.
