As several people have been asking after improved Beagleboard support with the Yocto Project, and it has been taking longer than I hoped to refresh the BSP, I thought I'd fill you in on what the plans are and where we are with those.
We met with the TI folks at ELC to try and sort out how to best support the Beagleboard in the Yocto Project while still preserving the excellent community surrounding the Beagleboard and the top-notch support of the Beagleboard from the meta-texasinstruments layer. The plan is to merge the contents of the linux-omap_2.6.37.bb recipe into the linux-yocto_2.6.37.bb recipe. This involves merging linux-omap into linux-yocto as well as merging the 200 or so patches from the linux-omap recipe patch series. This work is complete. Thanks to Bruce Ashfield for merging the linux-omap git tree. Of the 200 patches, I was able to drop several that reverse applied to the linux-yocto tree, or that weren't particularly relevant to the Beagleboard. Beyond the kernel patches, there is the question of the defconfig. Kernel configs are tricky as they include platform config, optional driver configs, and various bits of policy. The goal has been to include all of the platform config and the relevant driver configs, while ensuring the policy configs are consistent with the yocto/standard branch. This includes things like filesystem support, networking protocol options, etc. This work is about half complete. At this point I ran into the same problem reported by Gary Thomas here: https://lists.yoctoproject.org/pipermail/poky/2011-June/006634.html I found that by building with gcc 4.5.1, I am able to boot the Beagleboard using a linux-yocto-2.6.37 kernel and a core-image-sato image. I've tested serial, USB, ethernet, audio, and X. There are some quirks to be ironed out: o Fix gcc 4.6.0 build o Sometimes the /dev/fb0 device doesn't appear - workaround is to create it manually: # mknod /dev/fb0 char 29 0 but obviously a permanent solution is needed o Screen resolution doesn't fit on _my_display, need to see if this is specific to me, or a general problem o Finish pruning the kernel config With that, we'll have decent general purpose support for the Beagleboard in the Yocto Project. meta-texasinstruments should still be considered the upstream, and there are some things that will remain only there. Such as the snazzy Beagleboard Linux boot logo and the orange screen on DVI from u-boot. At this time, we haven't yet explored video acceleration or expansion board support, although we will include the bluetooth and wifi drivers from the meta-ti config. I'd like to thank everyone who has shown interest in this effort and especially those who have tried the build, opened bugs, and are helping to investigate open bugs.
