hack hack hack, the little machines fight back
Hi all,
Just wanted to let you guys know that I managed to make a serial console cable for my GP2X today by buying the Samsung E810 cable (for the EXT2 connector), then rewiring it and using a MAX232-based circuit to do TTL->RS232 conversion .. and it works!
now its time to start building kernels ..
