Hi, Dear experts:
We designed a t2080 custom board refer to T2080RDB-PC. And we deleted the CPLD, and used fixed pins
connection in contrast to T2080RDB-PC.
I burn the RCW(0xe8000000 ~ 0xe801ffff) and U-BOOT(0xeff40000 ~ 0xefffffff) to custom board's NOR FLASH, then it can not start up!
I use the CodeWarroir debug the U-BOOT, It shows that it stop at "STD_EXCEPTION(0x0e00, InstructionTLBError, UnknownException)" in start.s.
The RCW register is shown as attachments.
I think the RCW has loaded and have jumpped to the U-BOOT. But, Why it stopped at start.s?
What shoud I modify the RCW or U-BOOT or Hardware?
Expecting your reply and Thank you very much!
