What's the best way to build a ubuntu image (from source)?

Hi,

I've been working with Wandboard, recently just using their prebuilt ubuntu image for a small audio/video application I'm working on.

Thus far I've used Wandcam, and it just works.  Now I need to hook up different camera, so now I need source.

I've tried several approaches...

I walked through Robert Nelson's excellent set of steps here but it doesn't appear to include the drivers/media/platform/mxc/* code in the kernel tree it uses.

I've also built/used the yocto-based platform, but for reasons beyond the scope of this text, I need ubuntu.

The SDK stuff at wandboard.org is apparently from May of 2014, so I'd like to start with something a bit more up-to-date; besides, that SDK doesn't mention anything about ROOTFS,.

 

I've built the http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/snapshot/rel_imx_3.14.28_1.0.0_ga.tar.gz

with imx_v7_defconfig, but that's not wandboard specific.  I tried pulling in the wandboard_defconfig from

their github, but that build fails.

 

A while back I did a custom iMX6 board using Buildroot; however that too (AFAIK) does not help with ubuntu.

 

Any thoughts here would be helpful.

Ed
