qi built here

4) Setup bootloader [[U-boot]], [[U-boot-gena2x]] or [[Qi]]:
 +
 
 +
4.1) configure U-boot [[U-Boot_commands#Environment]]
 +
 
 +
change kernel parameters from:
 +
<pre>
 +
rootfstype=jffs2 root=/dev/mtdblock6
 +
</pre>
 +
 
 +
to:
 +
<pre>
 +
rootfstype=ubifs ubi.mtd=6,2048 root=ubi0:om-gta02-rootfs
 +
</pre>
 +
 
 +
4.2) update Qi with dfu-util
 +
 
 
http://build.shr-project.org/shr-unstable/images/om-gta02/  
 
http://build.shr-project.org/shr-unstable/images/om-gta02/  
is still using jffs2 in kernel params
 
but you can use the binary from here
 
http://jama.homelinux.org/org.openembedded.shr.images/om-gta02/qi-s3c2442-1.0.2+gitr0+c38b062a609f1442e6a9e13005cfbdfd59a5ac0d.udfu
 
or build Qi yourself with bitbake from latest shr/merge branch + this patch:
 
http://jama.homelinux.org/org.openembedded.shr.images/om-gta02/0014-qi-update-kernel-params-for-ubi-rootfs.patch
 
  
4) flash 2.6.32 also to NAND
+
qi-s3c* expects jffs2 as rootfs
  
5) boot it, test it, play with it
+
qi-ubi-s3c* expects ubifs as rootfs (with rootfs name om-gta02-rootfs which corresponds to name in ubinized image)
  
(Written by Martin Jansa [http://www.mail-archive.com/community@lists.openmoko.org/msg56825.html])
+
it is now in OE repository as qi_git.bb and qi-ubi_git.bb.

 +
# make shure that Qi is booting the NAND ( remove sd card or touch /boot/noboot-GTA02 )
 +
#: boot GTA02 with Qi (  switch it on )

How to test:
max_posedon provided some bonnie++ results from UBI (http://pastebin.ca/1739342) using kernel 2.6.29
+
Please run 'bonnie++ -u 0:0 -s 32 -m 16 -r 16' on a fresh filesystem. bonnie++ is now in shr-unstable feeds. (Note that this example uses only a 32MiB file, which easily fits in the GTA02's RAM and does not provide accurate speeds due to Linux's disk cache. For good results, use at least '-s 300').

[edit] With kernel 2.6.34

1) booting 2.6.34 kernel on uSD

http://build.shr-project.org/tests/mrmoku/2.6.34/images/om-gta02/

(Please note as of July 2010 unstable is 2.6.32+: http://build.shr-project.org/shr-unstable/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) Setup bootloader U-boot, U-boot-gena2x or Qi:

4.1) configure U-boot U-Boot_commands#Environment

change kernel parameters from:

rootfstype=jffs2 root=/dev/mtdblock6

to:

rootfstype=ubifs ubi.mtd=6,2048 root=ubi0:om-gta02-rootfs

4.2) 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

(Written by Martin JaMa Jansa [1])

[edit] Alternative

( using slower but always available dfu-util )

  1. update Qi with dfu-util
    dfu-util -a u-boot -R -D /qi-ubi-s3c2442-1.0.2-r1+gitr0+c38b062a609f1442e6a9e13005cfbdfd59a5ac0d.udfu # for gta02
  2. install kernel
    dfu-util -a kernel -R -D ./uImage-2.6.29-oe11+gitr119862+a15608f241a40b41fed5bffe511355c2067c4e88-r8-om-gta02.bin 
  3. install rootfs
    dfu-util -a rootfs -R -D  /home/ew/Desktop/shr-full-eglibc-ipk--20100507-om-gta02.rootfs.ubi #  not the rootfs.ubifs image use rootfs.ubi file!
  4. make shure that Qi is booting the NAND ( remove sd card or touch /boot/noboot-GTA02 )
    boot GTA02 with Qi ( switch it on )

[edit] Performance

How to test: Please run 'bonnie++ -u 0:0 -s 32 -m 16 -r 16' on a fresh filesystem. bonnie++ is now in shr-unstable feeds. (Note that this example uses only a 32MiB file, which easily fits in the GTA02's RAM and does not provide accurate speeds due to Linux's disk cache. For good results, use at least '-s 300').

[edit] Status

[edit] 12.5.2010

dfu-util confirmed to work too (by pwgen), but will be slower than nandwrite.

Personal tools

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 qi built here http://build.shr-project.org/shr-unstable/images/om-gta02/ is still using jffs2 in kernel params but you can use the binary from here http://jama.homelinux.org/org.openembedded.shr.images/om-gta02/qi-s3c2442-1.0.2+gitr0+c38b062a609f1442e6a9e13005cfbdfd59a5ac0d.udfu or build Qi yourself with bitbake from latest shr/merge branch + this patch: http://jama.homelinux.org/org.openembedded.shr.images/om-gta02/0014-qi-update-kernel-params-for-ubi-rootfs.patch

4) flash 2.6.32 also to NAND

5) boot it, test it, play with it
