Contents

With kernel 2.6.32

1) booting 2.6.32 kernel on uSD

http://build.shr-project.org/tests/mrmoku/2.6.32/images/om-gta02/

download uImage to /boot

download modules and untar it to /

update uImage link in /boot


2) flash image

flash_eraseall /dev/mtd6

nandwrite -p /dev/mtd6 shr-full-eglibc-ipk--20100105-om-gta02.rootfs.ubi


3) then test if it works

ubiattach /dev/ubi_ctrl -O 2048 -m 6

mount -t ubifs ubi0:om-gta02-rootfs /media/om

ls /media/om


4) update Qi with dfu-util

http://build.shr-project.org/shr-unstable/images/om-gta02/

qi-s3c* expects jffs2 as rootfs

qi-ubi-s3c* expects ubifs as rootfs (with rootfs name om-gta02-rootfs which corresponds to name in ubinized image)

it is now in OE repository as qi_git.bb and qi-ubi_git.bb.


5) flash 2.6.32 also to NAND


6) boot it, test it, play with it

With kernel 2.6.32

1) booting 2.6.32 kernel on uSD http://build.shr-project.org/tests/mrmoku/2.6.32/images/om-gta02/ download uImage to /boot download modules and untar it to / update uImage link in /boot

2) flash image flash_eraseall /dev/mtd6 nandwrite -p /dev/mtd6 shr-full-eglibc-ipk--20100105-om-gta02.rootfs.ubi (almost the same ubinized image will finish build in few mins as http://build.shr-project.org/shr-unstable/images/om-gta02/shr-full-eglibc-ipk--20100105-om-gta02.rootfs.ubi)

3) then test if it works ubiattach /dev/ubi_ctrl -O 2048 -m 6 mount -t ubifs ubi0:om-gta02-rootfs /media/om ls /media/om

3) update Qi with dfu-util http://build.shr-project.org/shr-unstable/images/om-gta02/ qi-s3c* expects jffs2 as rootfs qi-ubi-s3c* expects ubifs as rootfs (with rootfs name om-gta02-rootfs which corresponds to name in ubinized image)

it is now in OE repository as qi_git.bb and qi-ubi_git.bb.

4) flash 2.6.32 also to NAND

5) boot it, test it, play with it
