Dear All，
I’m porting uclinux-2.6.22 to Winbond W90N740, this is an ARM7TDMI-based CPU. This time , the following error occurred, I don’t know how to find the bug. Is there anyone can help me? This board has 32MB SDRAM(0x00000000 ~ 0x02000000) and 2MB Flash(0x7F000000 ~ 0x7F1FFFFF) after remapping the SDRAM and Flash, Thanks for any suggestion. Darwin Chen.
