[U-Boot] U-boot MIPS ROM Exception Handler Error

[Gurumurthy G M]

Hi all,
       I am porting U-boot-2010.03 on MIPS32 Architecture ( au1350 processor). u-boot is compiled for little endian and downloaded the u-boot.bin file to NOR Flash.After reset followed by go command , I observe that cpu hangs at 0xbfc00570 (ROM Exception Handler).

we are using BDI3000 debugger and bdiGDB for programming.

please let me know where is the problem? whether I am missing something.

Regards,
Gurumurthy
