[Buildroot] [Bug 563] New: compiling Linux 2.30.2 for ARM with Atmel support

              Host: Mandriva Linux 32bit
            Target: arm_generic
           Summary: compiling Linux 2.30.2 for ARM with Atmel support
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Outdated package
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: oduclos at mandriva.com
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


I tried to compile Linux 2.30.2 for ARM with the Atmel devices support but it
failed.

The patch "linux-2.6.28-at91.patch.bz2" only works with linux 2.6.28 and should
not be used with other kernels.

I'm not sure how to handle this bug. For sure, a patch designed to be applied
on a particular kernel version will only apply on this particular version. And
it seems that in Buildroot, Atmel patches are only available up to 2.6.28.
Which means that newer kernels have not been integrated yet. What behaviour
would you expect from Buildroot here ?

I'm assigning the bug to Ulf Samuelsson, who usually handle Atmel-specific
issues in Buildroot.

You need to check my personal git, where there is support for:

linux-2.6.30.2
u-boot-2009.08-rc1
at91bootstrap-2.12 (soon 2.13-rc1)

Bootstrap compiles on all supported boards.
Only loaded to a SAM9263EK booting from dataflash.

U_boot has been compiled on the SAM9263/SAM9G10/SAM9G45,
but only loaded to a SAM9263EK

Linux has been compiled for SAM9263/SAM9G10/SAM9G45,
but again only loaded to a SAM9263.

After some hassle I have gotten mplayer to play mp3 files
and I can also display jpeg pictures, although
the BGR LCD controller is not supported.
(mplayer assumes RGB)

I have added all the patches I have found on the linux arm mailing
list, except the MCI patches, but I hope to add them later.

It obviously needs more testing, but thats why we are working
in a collaborative project, right.



Personal gits are available at http://git.buildroot.net/

The git in question is:

git://git.busybox.net/~ulf/git/atmel-2009-08-rc2

Thanks. Will the content of this it repo be included in the next stable release
?

If you ask, I think buildroot should at least print an error message when
detecting such incompatibilities.

I've been waisting a lot of time these past few days trying to generate an
image as I want, but there are so much of bugs and incompatibilities !

You can apply any patchset you want, the config is just an easy short cut.

When you try to build a non-working patch, you will get your error
message during the patch process.

You should expect the patch to work for the kernel version it was
designed for.

You do have the freedom to test the patch on a later kernel, and
for a range of kernels it will work, but don't expect a patchset
to work for all future versions.

If you want to use a patchset, on a later kernel than what is supported,
then you have to manually adapt the patches to your desired kernel
and then use the custom patch feature.
