I'm hoping to not repeat all the discussions that we've had around the beagle board here. Anything that applies to that applies here.

This is a reference BSP done by the Wind River folks on top of the linux-yocto kernel. It is not intended to be a replacement for any existing pandaboard efforts, but is intended to be used as an example of an integrated board.

Cheers,

Bruce

Would you mind re-summarizing the discussion? I know there has been a lot of back and forth, and it seems like a summary would be helpful for people who stopped following the discussion.

It is very confusing for many of us to see duplicate and or competing BSP's.

Would you mind re-summarizing the discussion? I know there has been a lot of back and forth, and it seems like a summary would be helpful for people who stopped following the discussion.

Darren's the right person to give a proper summary, since he was driving our beagleboard work. But he's out on Jury duty at the moment, so we'll have to wait. I can attempt a quick summary here.

The goal of a BSP like this as part of meta-yocto and linux-yocto are this for any BSP:

Goals:
1) <vendor/semi> needs meta-<vendor/semi> to maintain its role as the definitive source for <vendor/semi> BSPs and drive
fragmentation down.
2) The Yocto Project meta-yocto layer has a goal to provide stand-alone BSPs that demonstrates the multi-architecture features of the Yocto Project.

To to this, we have the challenges:

A) Using meta-<vendor/semi> with the Yocto Project
B) Aligning on kernel versions
C) Kernel policy definition and ownership
D) Not detract from upstream-first efforts .. and more.

So the meta-<foo> issues will be solved going forward with layer tooling, the kernel version alignment will never be solved completely but can be addressed via working with the right upstream and sources with the right process.

So to get that kernel alignment, tooling, common feature set and have a set of BSPs that can share tests, results, support, etc, there is a need to do yocto integrations of identified BSPs. We've (largely) agreed to live with some repeated effort in the short term and recognize that what you see here is not intended to replace a community or vendor effort, but should be considered as a stepping stone and proof of concept. If the latest and greatest, bleeding edge is what people want, then the other meta-* layers are the way to go.

I think that's enough for now, I tried to do the conversations justice and keep this short, so my apologies to anyone reading this if I missed something.

Cheers,

Bruce

I was thinking about this point over the weekend, and I realized that it may not have been clear that I'm talking largely about the kernel here. Not all the associated userspace/config, etc that we'd consider as part of a complete solution. Obviously any kernel tree can support multiple boards, and what we have here is an example against the 2.6.37 yocto kernel tree and kernel feature set.
