Hi! Friends,
We design our i.MX53 board based on SMD design. I downloaded the newest Linux BSP for SABRE tablet and installed on my Ubuntu 10.04 environment. I used the procedure described in the i.MX53_SABRE_TABLET_Linux_BSP_UserGuide.pdf
./L2.6.35_11.01.00_ER_source_bundle/install
./ltib -m conifg
Choosing imx5X platform and package profile, MIN profile. In Kernel configuration, choosing i.MX53SMD board. Then everything as default.
After that, I use the u-boot.bin and uImage in the boot directory under rootfs to do the following.
$sudo dd if=u-boot.bin of=/dev/sdb bs=512 && sync && sync
$sudo dd if=uImage of=/dev/sdb bs=512 seek=2048 && sync && sync
$sudo umount /dev/sdb*
$sudo fdisk /dev/sdb
enter the following commands: u, n, p, 1, 8192, "enter", w
And then
$sudo mkfs.ext3 /dev/sdb1
$sudo mount /dev/sdb1 /home/<user>/mountpoint
$cd /home/<user>/ltib/rootfs
$sudo cp -rpa [A-z]* /home/<user>/mountpoint
$sudo umount /home/<user>/mountpoint
Then I set up all environment variables based ont he pdf file. However, I came across the following error messages.
============
VFS: Cannot open root device "mmcblk0p1" or unknown-block(179,1)
Please append a correct "root=" boot option; here are the available partitions:
b300 3880960 mmcblk0 driver: mmcblk
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)
============
I think I may have two things different from the description in the pdf file. One is that I did not apply the patch. The other is that my OS is Ubuntu 10.04, not 9.04.
Could anyone shed some light for my mistakes?
Vincent
