Hi Alexandre,

Thanks again for your response. I think mainline BuildRoot is the way to go.

Just two quick questions on the commands to apply your patch...from BuildRoot documentation.

$ git checkout -b <test-branch-name>
$ wget -O - <mbox-url> | git am

Q1: Does <test-branch-name> = http://git.buildroot.net/buildroot/tag/?id=2015.02 ?
Q2: Does <mbox-url> = http://patchwork.ozlabs.org/patch/473928/mbox/ ?


21.3.1. Applying Patches from Patchwork
The main use of Buildroot's Patchwork website for a developer is for pulling in patches into their local git repository for testing purposes.

When browsing patches in the patchwork management interface, an mbox link is provided at the top of the page. Copy this link address and run the following commands:

$ git checkout -b <test-branch-name>
$ wget -O - <mbox-url> | git am

If so and you only support mainline BuildRoot then why does Alexandre's sam9x5ek patches contain Linux4sam URLs (ie URL=https://github.com/linux4sam/linux-at91.git and URL="git://github.com/linux4sam/u-boot-at91.git" ) shown here http://patchwork.ozlabs.org/patch/473928/

Atmel is. I'm using their version of the kernel, u-boot and at91bootstrap because they are maintaining stble versions of each.

> 4.       OK, if Alexandre's patch does not work on Atmel's forked BuildRoot then I will try using mainline BuildRoot. In fact, I'll probably try both BuildRoot versions no matter what. I'll read the manual at http://buildroot.uclibc.org/downloads/manual/manual.html

It will also work on buildroot-at91 but this doesn't make any sense to try that. As it is older and is actually outdated.
