Hi,

Days have gone by and I had tried several things but still no luck of resolving this issue. With this part I'm seeing MTD errors that I think I've traced to cfi_cmdset_0001.c that I'd like to ask about. I removed the commented CMDSET0001_DISABLE_ERASE_SUSPEND_ON_WRITE and CMDSET0001_DISABLE_WRITE_SUSPEND in cfi_cmdset_0001.c, but the result is the same "buffer write error (status 0xb0)". According to the datasheet, 0xb0 means program or erase suspend. I am able to flash_eraseall /dev/mtd0 without the "-j" clean marker, but when I tried to flash_eraseall -j /dev/mtd0, it gives me the same error. why?
