Hello, all. I got this one from dealextreme. It is known to be rebranded and sold by some local vendors. Basically, it's just another board with 4 MB of Flash and 32 MB of RAM running at 320 Mhz.
What is done: * Figured out correct GPIO LED pinning All 5+1 GPIO leds work fine via /sys/class/leds . * Both buttons at the back work (reset/wps and MODE). I assigned them KEY_RESET and KEY_M respectively. * Altered the scripts to correctly extract the firmware for wifi (Thanks to Layne Edwards for help) * Altered the scripts to pack the firmware correctly. Some photos of the router and the PCB are here: http://necromant.ath.cx/wp/2011/08/05/porting-openwrt-to-an-unbranded-3gn-router/ Patch for openwrt trunk is attached to this email. Regards, Andrew.
