Now I have spent the whole day on trying to mount the device from Linux as a read/write partition but without luck. I can mount the partition but if I try to do some writing to it I get: Write clean marker to block at 0x00030000 failed: -30 ... repeated for all sector boundaries. If I reboot the device the partition is empty. Then I tried to use flash_eraseall but it fails as well # flash_eraseall -j /dev/mtd1 Erasing 64 Kibyte @ 0 -- 0 % complete. flash_eraseall: /dev/mtd1: MTD write failure: Read-only file system I tried to unlock the flash (using protect off) before booting Linux but without any success. I can't find any configuration option related to the NOR CFI flash in the spear3xx kernel configuration files. Do you have any useful hint on this as well?
