Hi All, We are porting U-boot. 2010.03 version for MIPS32 processor (Au1350). Currently we are facing one problem:

When I compile u-boot and program to NOR Flash using bdiGDB through BDI3000 Debugger, I am observing u-boot hangs at exception i.e. at address 0xbfc00570 after reset .

error log is below:

Au1350>ti Core number : 0 Core state : Debug Mode Debug entry cause : single step Current PC : 0xbfc00400 Current SR : 0x00400004 Current LR (r31) : 0xbfc0f6e4 Current SP (r29) : 0x803fff00 Au1350>go Au1350>halt Core number : 0 Core state : Debug Mode Debug entry cause : JTAG break request Current PC : 0xbfc00570 Current SR : 0x00400002 Current LR (r31) : 0xbfc0f6e4 Current SP (r29) : 0x803fff00 Au1350>

After reset address 0xbfc00400, code executes lowlevel_init and subsequently hangs at 0xbfc00570 (RomException).

I'm attaching start.S and lowlevel_init.S files we are using.

Please let me know if am doing anything wrong or missing something.
