Hi all, thanks for your generous reply....
However, the problem persist...
As far as I know, correct me if wrong, SWWSR is for the DSP, I am
using the ARM7 for the interfacing.
I have configured the CS-reg, BS-config-reg with all kinds of wait
states...
The weired part is that, with the same config, it can run on the JTAG
(under SRAM) mode. But when switched to the Flash, the problems
appeared...

Any clues...

Thanks in advance!
