Dear all,
I have just replaced my WGT624 V3 flash from 2 MB(25P16) to 4MB (25P32) for I was trying to get rid of the VXWorks Bootloader without jtaging it (due to the lack of information). After building a flash programmer, I was able to back up my router's firmware. The next step was copying my backed up firmware to a new 25P32 and booting the WGT624 in order to see if everything went right. The WGT624 recognized the extra space but it complained about the cheksum.
AR2316A SOC :
Flash amount check after IC replacement
Then using the source of the Redboot cobra from DD-WRT, I could compile a fresh Bootloader and I could give a try on it. It worked properly even though I couldn't set my MAC address properly.
First Redboot trial
Now, I am trying to build a good kernel to get my WGT624 back to life and free from VXWorks. However, up to now, I haven't succed. I have tried different OpenWRT flavors. I couldn't boot a Meraki's kernel on it so I tried the litestation 2, which I suppose is based on the ar2316 SOC, from Ubiquity. The router boots properly but the madwifi terminates on error. I tried to compile newer madwifi versions but I'm not as keen in linux programming as with hardware modifications.
The latest test I tried was using the fonera's port tailored to the WGT624 hardware, based on the kernel 2.4.36. Once again, It boots up properly (I even have access to the "fon's" console) but when the madwifi's modules are loaded the system crashes.

8005fbe0 ...I would like some help to compile the madwifi port or perhaps the new ath5k in order to replace them into the rootfs to bring back to a new life this nice piece of equipment
Regards.
