[Xenomai] How to port Linux 3.2.21 to beaglebone (TI AM3358 Cortex A8 SoC)

[tianlangroot]

As the TI AM3358 is not supported in 3.2.21 mainline kernel, I want to use the slightly patched kernel from linux-omap for Xenomai, but I don't know where should be changed in the Linux 3.2.21 source code. Can anyone help me?

Well, to do that, you have to apply xenomai patch to the linux-omap
kernel and fix the conflicts. But:
- the I-pipe patch for 3.2.21 has known bugs
- there is support for the beaglebone processor for 3.5, 3.8, 3.10,
without the bugs.

So, the question is: are you sure this is really what you want to do?

I am certainly not going to fix conflicts between a buggy patch and a
non-mainline kernel. So, I am afraid no, I will not help you.

However, same question again: why not using xenomai 2.6.3 and one of the
I-pipe patches it contains, including for beaglebone?
