Hi guys,
Once I duplicated linaro-ubuntu-desktop image into SD card following the instruction on linaro website and it works fine. Now I need to patch the kernel so that I compiled the patched kernel and copy the kernel image into /boot of SD card but my pandaboard doesn't boot up. Below is more detail steps I did so please let me know what I did wrong. Also if you have an instruction, then it also might be really helpful.
1. I'm using PandaBoard ES. To start the board, I just dd linaro-ubuntu-desktop image to SD card following these steps ( http://releases.linaro.org/images/): # These values will change based on your system $ SDCARD=/dev/ #sdcard could be something sdb or mmcblk0 $ IMGFILE=overo-nano.img $ gunzip ${IMGFILE}.gz $ dd bs=64k if=${IMGFILE} of=${SDCARD} Then the linaro ubuntu works on the PandaBoard ES well. In detail, the version of this ubuntu 12.02 and kernel version is 3.1.1-8-linaro-lt-omap.
2. Next, I cloned your git repository(git:// git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc.git) to get kernel including remoteproc patch. Since there's no .config file I just copy the config file of 3.2-rc4 on here ( http://elinux.org/Panda_How_to_kernel_3_2_rcx) wihch is the version matching the kernel version on your git repository. And then I compile the kernel and modules to get an uImage and install modules with commands below (also explains http://elinux.org/Panda_How_to_kernel_3_2_rcx), and copy uImage to /boot on SD card and modules /rootfs/lib/ on SD card. I used arm-linux-gnueabi-gcc rather than arm-none-linux-gnueabi-gcc.
Then compile like so: make ARCH=arm CROSS_COMPILE=Path_to_your/arm-2010q1/bin/arm-none-linux-gnueabi- uImage Then compile the modules like so: make ARCH=arm CROSS_COMPILE=/home/kenm/Panda/arm-2010q1/bin/arm-none-linux-gnueabi- modules "Install" the modules to somewhere convenient: make ARCH=arm CROSS_COMPILE=/home/kenm/Panda/arm-2010q1/bin/arm-none-linux-gnueabi- INSTALL_MOD_PATH=../testlib_omap modules_install
3. Then I put SD card to the Panda Board but it's suspending with the booting logs below.

Do you have any guess what I have missed or didn't do something? Any of your advise would be more than welcome. Thanks for your patches, and I really appreciate your consideration and help.
Thanks, Jaeyeon
