Problem writing/reading to External CE using DSK5510

Hi everyone,

I am having problems writing/reading to CE2 using the DSK5510.
My code for writing looks like this

#define ABCD 0x400000
#define ABCD_PTR (*(unsigned volatile char*)ABCD)

ABCD_PTR = 0x25;

Any help will be appreciatedd
Thanks a lot

I meet the same problem with using CE1 to read/write asynchronous
flash
configure EMIF registers (TMS320VC5509A) as following:

EMIRST 0xFFFF
EGCR 0x0620 (16bits width)
CE11 0x1122
CE12 0x010F
CE13 96

when invoke *(volatile Uint16*)(0x400000+Addr)=0xAA55
nothing happen to A0~A13 and D0~D15
and #CE1 line keeping high.

If you find a solution to this problem, pls share with me.
thank you!
