How to upgrade the factory firmware
Overview of How-To
This How-To is meant to be a starting point for people to learn how to upgrade the factory firmware for IGEP v2 devices as quickly and easily as possible.
This How-To works with the Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions.
Requirements
- Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine
Upgrade the factory firmware
Upgrade the firmware using an NFS-TFTP environment
First of all setup a poky-image-sato NFS-TFTP environment using latest images as explained in Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine
With this kernel the partitions looks like,
# cat /proc/mtd dev: size erasesize name mtd0: 00080000 00040000 "X-Loader" mtd1: 00180000 00040000 "U-Boot" mtd2: 00080000 00040000 "U-Boot Env" mtd3: 00300000 00040000 "Kernel" mtd4: 1fa80000 00040000 "File System"
To flash files to mtd partitions just use the nandwrite program. For example, to flash the firmware factory v3.2.1-0 download from
and copy to target directory /home/root in your board, then follow next steps
# cd /home/root/firmware-factory-igep0020-3.2.1-0
# for i in 0 1 2 3 4; do flash_eraseall /dev/mtd${i}; done
# nandwrite -p /dev/mtd0 x-load-ddp-1.4.2-2.igep0020-flash.bin.ift
# nandwrite -p /dev/mtd1 u-boot-arm-2009.11-1.igep0020.bin
# nandwrite -p /dev/mtd2 u-boot-environment.bin
# nandwrite -p /dev/mtd3 uImage-2.6.28-r4-igep0020-20100321091933.bin
# nandwrite -p /dev/mtd4 poky-image-sato-igep0020-20100321084218.rootfs.jffs2
Restart your board and enjoy your new firmware. That's all folks.
