Chime in easily! I have made my flash_eraseall use mtd-snapshot-20050217 and mips-linux-gcc cross compiler, but I got this error message as below: ========= # ./flash_eraseall /dev/mtd2 MTD_open MTD_ioctl MTD_ioctl Invalid ioctl 80084d0b (MEMGETINFO = 40204d01)
./flash_eraseall /dev/mtd2: MTD get bad block failed: Inappropriate ioctl for device ========= I don't know how to fix it. 2007/3/22, Aubrey Li <[EMAIL PROTECTED]>:
