Hi,

I am trying to boot kernel on panda board. I got the source from: http://git.linaro.org/gitweb?p=kernel/linux-linaro-tracking.git%3Ba=shortlog...

Following is my branch HEAD:

commit 7f39bb7ab9591c6254e5930a00d762e4b37f08b2 Merge: 1d10459 8b29cd5 Author: Andrey Konovalov andrey.konovalov@linaro.org Date: Mon Sep 3 17:10:24 2012 +0400

Merge branch 'tracking-ll-last-minute-fixes' into merge-linux-linaro

I am using following for compilation: omap2plus_defconfig, omap4-panda.dts

When i try to boot, kernel hangs after uncompressing linux... If i just remove the 0x815f0000 from bootm command.. i.e. boot without dtb... it boots fine.

Earlier i have flashed my card using linaro-media-create. Got, H/w package and devel rootfs from 12.08 release. Replaced uImage and board.dtb in /dev/mmcblk0p1

Unfortunately Panda is not supported by the LT at this tree yet, so the best thing to do is to try just the latest upstream kernel (from git.kernel.org) and see if you're able to reproduce the same issue with it (or just use the old 3.4 based tree from the LT).

I believe Viresh has tried mainline as well. But some DT bits might be missing from there. Without DT, things start working and that is the route we'll take if we're unable to get help with LEB u-boot command-line parameters and 3.6 kernels on Pandaboard.

We're coming up on 3.6 soon. Do we know when we'll have updated OMAP support?

I think the LT started working on the 3.6 series already, but that would probably contain tons of patches and not the ones we might need for proper DT support.

Andy, do you know if we could get a topic/branch with enough support for at least booting with proper DT support? It might be that we need to update the dtb file to reflect what is currently supported, and I believe that would help even more if we could fix upstream while 3.6 is not yet released.

Cheers,

Actually mainline image was working with DT, but i wanted to work on Linaro tree to get latest patches on various topics...

That's interesting. Which rev from upstream did you use?

I know Andrey is updating linux-linaro this week, which should be on top of 3.6-rc5.

Cheers,
