minimal template layer for new machine support

minimal template layer for new machine support

[Tilman Baumann]

Hi,

I'm working on a TI DM812x support overlay.
I guess what it comes down to is a new kernel recipe (based on TI's 
sources) and this funny two stage u-boot.
I think I can write the recipes. But what I don't quite see is how I 
would add a new supported machine in the first place?
I was trying to orient myself on a few existing machine support layers. 
But I think I'm still missing the point.
What are the minimal basics to implement? Where should I start?

Thanks for any help.

Cheers
  Tilman

check meta-ti
http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/

may be there is a BSP already or something similar you can start off.

Oh, great. I think I can work with that.
I only knew the Arago project, but that is not based on oe-core.

Thanks

As far as I know, there also exists an effort by the meta-ti people to
port the original Arago distro to the new layered architecture over
oe-core: this is called meta-arago
(http://arago-project.org/git/?p=meta-arago.git;a=summary).
You'd better ask on the meta-ti list what the state of the art is for
this project, but I think it is supposed to work with meta-ti and
provide an alternative distro layer to Angstrom.

It seems to be lacking the board support for dm813x-evm.
I will ask the arago guys about it.

But really, since I still have to do kernel and u-boot from scratch, I 
don't think I gain much. (I can't use the original TI stuff.)
I guess if I would grokk how a basic hardware enablement layer is done, 
I would be better off.

Thanks
