Based on your previous e-mail (with little to no CFI debug output displayed
after explicitly enabling cfi_flash driver debugging as I had recommended : )
I suspected that you may be using that now obsolete board/omap1510inn/flash.c
driver instead. It was recently replaced by drivers/cfi_flash.c. Please do a
cvs update and retest using the current cfi_flash driver and see if that works.
It does seem to work well for me.
