i started playing with the CONFIG_SYS_FLASH_USE_BUFFER_WRITE option, and it seems to work fine with an intel strataflash. but when i tried using it with an ST M29W640 part, no writes are ever committed to the flash.
are there any known gotchas with this code before i start poking further ?
Not that I am aware of. I am using it on all my Intel/Numonyx and AMD/Spansion NOR flash equipped boards without any issues. I don't remember using it on a ST device though. Not sure what's going wrong there, sorry.
I'm running a combination of Intel StrataFlash and AM29LV040B (equivalent to ST29LV040B) and I cannot enable CONFIG_SYS_FLASH_USE_BUFFER_WRITE either - I don't think the AM29 device supports it :(
