Alright, I tried that; here are my results: [EMAIL PROTECTED] ~] $ cat /proc/mtd dev: size erasesize name mtd0: 00200000 00010000 "physmap-flash.0" mtd1: 00040000 00020000 "u-boot" mtd2: 00040000 00020000 "u-boot_env" mtd3: 00800000 00020000 "kernel" mtd4: 000a0000 00020000 "splash" mtd5: 00040000 00020000 "factory" mtd6: 0f6a0000 00020000 "rootfs" [EMAIL PROTECTED] ~] $ flash_eraseall /dev/mtd3 Erasing 128 Kibyte @ 7e0000 -- 98 % complete. [EMAIL PROTECTED] ~] $ cat uImage.bin > /dev/mtd3 cat: write error: Invalid argument [EMAIL PROTECTED] ~] $ file uImage.bin; du -h uImage.bin; file /dev/mtd3 uImage.bin: u-boot/PPCBoot image 1.8M uImage.bin /dev/mtd3: character special (90/6) Any ideas? Do I need to do something special before I can directly write to /dev/mtd3? In the meantime I'm going to just flash in the u-boot... -- Kelvie Wong
