Linux-omap Kernel patches for beagleboard

GoogleGroups

Hi all,

I need to build a linux-omap >= 2.6.34 kernel for beagleboard.
To build a 2.6.31 kernel I used the patches (dss2 , musb ... ) that I found in the OpenEmbedded tree , but I didn't find nothing about linux-omap updated versions (2.5.34-rcx 2.6.35-rcx)

Does anyone know where to find beagleboard patches for updated linux-omap kernel versions ?

In the beagleboard wiki I found the << git://git.mansr.com/linux-omap >> repository that ,if I understood, contains patched kernel sources for beagleboard, is that correct ?

Thanks in advance

Best Regards

Enrico

Why don't you just use linus's mainline 2.6.35-rc's, specially since
almost everything is now in there for the beagle bx's/cx's with the
omap3_defconfig...

That's actually just a staging tree to get stuff into Linus's main
kernel now.. So you can use that or Linus's

Hi Robert,

thanks for the good info, that most of the patches are already in the
vanilla kernel.

But in case I would like to build a specific version of the kernel
with custom config, am I wrong to think that taking vanilla 33.5 +
patch at the

http://www.rcn-ee.net/deb/lucid/v2.6.33.5-l3/patch-2.6.33.5-l3.diff

would give me the 33.5 kernel with beagleboard support ?

Hi Maksym,

That's correct, that diff is for 2.6.33.5 (the defconfig in the same
directory is for reference, so you can do anything you want their....)

But i would really stay away from 2.6.33 I was running into some weird
gcc issues, which is why i moved 2.6.34 to my stable tree so fast..

Robert,

I guess I don't have much choice. I would like to try the preempt-rt
patch as well, and the latest version is based on 33.6. The preempt-rt
supports exactly the versions which are not popular in the beagle
world 31, 33. Hope this syncs at 35 :slight_smile:

Thanks,
Maksym.

Okay, good reason to use it..

Here's what you have to watch out for: Just stay from Ubuntu Lucid's
native compiler in arm.. (it's the one that triggered it the most for
me, Maverick's native gcc is fine)

In a rare for me (use CodeSoucery's) or the very good angstrom gcc to
cross compile the kernel..

Thanks for advice, I'll probably go with angstrom.
