Description Darren Hart 2011-08-22 10:08:29 UTC 
Trying to compile linux-yocto-rt_3.0 fails for the beagleboard. This is not surprising as we haven't sync'd the 3.0 tree or the .config with something from TI (they were on 2.6.39 last I checked). This needs to be addressed, but releasing 2.6.37 for 1.1 may be required.

Comment 1 Darren Hart 2011-08-22 10:09:51 UTC 
Bruce, I'm marking this as Medium prio for post 1.1. Let me know if you have different plans for the non-rt Beagleboard BSP as we will want to align there.
Comment 2 Bruce Ashfield 2011-08-22 10:10:39 UTC 
This is the right level/plan. Leaving the beagleboard on 2.6.37 is the primary plan for this BSP. But we'll have a look at this none the less, if only to accelerate the post 1.1 work.

Thanks liming. Launching a build to test.
Comment 5 Bruce Ashfield 2011-08-24 05:36:48 UTC 
This does fix the build. I'll push it out today.

Hi Darren,

This bug has been fixed, please help us to verify this bug and mark it "verified fixed", thanks a lot!
Comment 8 Darren Hart 2011-09-22 11:51:37 UTC 
You still have to manually enable building beagleboard in the linux-yocto-rt_3.0.bbappend in meta-yocto, but it does build successfully. I have not been able to test the kernel on real hardware.
