Ö÷Ìâ£º [uClinux-dev] The fatal errors about ucLinux-2.6.22

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.
