Building for pandaboard

Building for pandaboard

[Brian Park]

[-- Attachment #1: Type: text/plain, Size: 787 bytes --]

Hi,
I'm interested in using Yocto to build linux for PandaBoard. It seems there
are already patches some where that I can use to build for panda, as I found
some discussions mentioning PandaBoard patch in the archive. But I could not
apply it. I'd appreciate some pointers on how to find and apply the right
patch.

Just trying to apply
http://article.gmane.org/gmane.linux.embedded.yocto.general/2037/match=pandaboardas
a patch using "git am" command gave the following error. I'm using
release 1.1 Edison.

briansp@LinuxMint11 ~/poky $ git am < ~/Documents/pandaboard.patch
previous rebase directory /home/briansp/poky/.git/rebase-apply still exists
but mbox given.

I'm new to developing for linux and yocto. So, any help would be
appreciated.

Thank you

Brian

Those same patches are merged into the 2.6.37 kernel tree here:

http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-2.6.37/log/?h=yocto/standard/pandaboard

So if you do want to use the linux-yocto kernel, you could set
your preferred kernel version to 2.6.37 and you'd get that
kernel and branch for the board.

But like anything, nothing is completely simple, the support in
the 2.6.37 tree was contributed in an effort to add some more board
support to a yocto tested/standardized kernel. There are multiple
sources for pandaboard support, with different functionality (i.e. 
deeper, different kernel version, etc), different integration and
different goals. i.e. angstrom and meta-texasinstruments.

To use the 2.6.37 support you'd need a configuration of the machine and
a meta layer defining the userspace. There was a prototype one that
floated around, but it was being re-worked to use layer tooling and not
duplicate effort that is in other layers already.

If you like, I can locate that layer and send it along, or you can
try out the other references I mentioned (others may have better /
more detailed information).

Cheers,

Bruce

Thanks for the info.
As I'm very new to Yocto, I'd not know how to create local.conf to build for
panda, even knowing that the kernel will support pandaboard. How would I go
about configuring Yocto to build for panda? If you can point me to some
documentation showing how to do it, I'd appreciate it.

I'm just learning yocto, in my spare time, and just went through the quick
start guide to build for x86qemu image and skimmed through the development
manual. But I'm not too sure how to go about configuring for pandaboard. I
figured, I can build for beagle board and then modify config to make it work
for panda. However, I'm having build issue when trying to build for beagle
board.

If there is already an existing pandaboard config, I'd like to try it.

Thank you.

That would likely work for userspace (minus the build error you
mentioned) with the appropriate config changes. But for the kernel,
there is a different set of patches for board support, so you do
need to pick the right layer and preferred kernel.

There is one floating around, I'll locate the latest tgz and you
can try it out in the yocto context (I say yocto, since as I've
mentioned there are other oe based configs and layers that can be
used for panda support as well).

Bruce

The best pandaboard support is present in the meta-ti layer, to use it just follow the instructions at http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/meta-texasinstruments/tree/README

  i am particulartly interested in this topic as i have two
pandaboards waiting to be yocto-ized.  might this be a more
appropriate topic for the pandaboard mailing list?
