update: the cfi driver in the version 1.1.0 displays:

so that's a success
however, when changing and saving environment variables, I get:
=> saveenv Saving Environment to Flash... Protect off FFFA0000 ... FFFBFFFF Error: start and/or end address not on sector boundary Error: start and/or end address not on sector boundary Error: start and/or end address not on sector boundary
I'll keep searching :-) i'll take a look at the changes in the cfi flash driver, and at my settings, maybe I screwed up something in the sector sizes

Hi,
The board configuration is based on the PPChameleonEVB board. The flash driver included (/board/dave/PPChameleonEVB/flash.[ch]) works on my board, and I can perform CFI commands manually. Is it nevertheless possible that there is an hardware problem preventing software to execute those CFI commands?
Best Regards
Nicky Geerts

I have been changing configuration settings, but to no avail. I even tried defining __LITTLE_ENDIAN ;-)
You should look at your HW configuration: we've had issues like that during the startup of our board and I hardcoded it 128N detection in U-boot, even submitted a patch for this (which was correctly rejected by Wolfgang).
After another round of checking the design, we've had no issues whatsoever with this Spansion flash chip (or 256N).
