Hi, all
I met a problem that the omapzoom and aosp build of panda can't be booted up in lava. here is the bug link: https://bugs.launchpad.net/lava-dispatcher/+bug/1012546
When we passed the bootcmd and bootargs via u-boot, and run boot to boot the images deployed on partition3, the u-boot load kernel image and initrd file successfully, and displayed the line: "Uncompressing Linux... done, booting the kernel." but after this line, it seems that the board rebooted and boot the master image as default again, not boot up the android image.
I guess it has relation with uboot in master image because I have tried to use the MLO and u-boot.bin and u-boot.img in omapzoom build to replace the files on boot partition of master image, then I can boot the omapzoom and aosp build successfully. (also can boot the tracking build)
What I did was as following:
- deploy omapzoom build to sdcard with linaro-android-media-create
command 2. copy the MLO and u-boot.bin and u-boot.img 3 file from sdcard to someplace in local 3. use "./lava-create-master -r 2G panda" to create the sdcard used for master image we can get the lava-create-master script from lp:lava-master-image-scripts 4. plug in the sdcard and boot the board 5. wait the board to complete the partition job. after this, the uImage and uInitrd file in boot partition has been change, and then the master image can be booted with the uboot files from omapzoom build but I don't know why and what change has been done. 6. copy the MLO and u-boot.bin and u-boot.img 3 file to the boot partition of sdcard 7. plug the sdcard to the board and boot it, then it can be use to boot the tracking/omapzoom/aosp 3 builds of panda.
The version original u-boot for master image is: U-Boot 2011.12 (Feb 16 2012 - 21:46:14) The u-boot version of omapzoom build is: U-Boot 2011.06 (Aug 20 2011 - 18:00:16). The u-boot version of tracking build is : U-Boot SPL 2012.04.01 (Jun 14 2012 - 08:05:54) The tracking build works fine with the original uboot of master image.
So I guess there are some differences between the original uboot for master image and the uboot build in omapzoom build. Anyone know the details why it can not boot the omapzoom and aosp build on the 3rd partition, and if I can boot the omapzoom and aosp build of panda with the original u-boot of master image?
The kernel from aosp/omapzoom doesn't seem to boot with the uboot-SPL built from linaro-uboot. The kernel booted with linaro-uboot seems to be giving kernel panic. This was the reason I had to revert to older MLO and uboot release.
