Re: [Xenomai] Beaglebone kernels - automated builds WIP

[Flavio Castro Alves Filho <flavio.alves@gmail.com>]

Answering my own question:

=> My setup

Ubuntu 12.04 with a complete build of Angstrom for BeagleBone Black
using openembedded setup scripts

I used 'bitbake meta-ide-support' in order to have the toolchain for
building the kernel.

Despite having the build system, I'm using the original image from
e-mmc without changing anything

=> My procedure

* I used ipipe.git repository and ipipe-next branch as my mainline
kernel source code. I assumed that it was equivalent to the mainline
kernel with the v3.8.10 tag with the additions of the adeos-ipipe
equivalent patches (if we use the Xenomai's installer from the
download package)
* I added the BeagleBone Black related patches. To do so, I got the
meta-beagleboard from Yocto/Angstrom, checkout the hash which they've
just committed the v3.8.10 kernel for building and copied the patches
and configuration file
* I applied those patches to ipipe. It failed in one patch, but when I
saw, it was just #include positions. I corrected by hand.
* Executed scripts/prepare-kernel.sh, to install Xenomai patches
* Run menuconfig, to correct the real time part of the configuration file
* Build the kernel. It worked straight
* Copied the uImage file to the board

* Compiled Xenomai and installed to the board. In my case, I created a
recipe and installed the ipk file into my image.

I'll try to organize it in order to have an easier way to have it done.

Best regards,

Flavio
