Hi,
I try to get Xenomai run on a Beagle-XM rev c.
That's what I use:
*) xenomai-head commit 9534fff1f0247c4c1a9bd104b0ef65df340ead4f
*) ipipe-core-3.2.21-arm-1.patch
*) ELDK 5.2.1 generic-armv7a
*) linux-stable 3.2.21
*) rootfs on 2nd partition of SD card (for now)
*) kernel loaded over tftp
That's what I observed so far:
1) default config
*) default kernel boots
*) ipipe patched kernel hangs:
Filename 'beagle-xm/uImage'.
Load address: 0x80200000

What version of the Linux kernel? Is it a vanilla 3.2.21?

As repeated many times on this list and probably on the linux-arm-kernel
mailing list too, in that case, use earlyprintk.

As repeated many times on this list, a stack trace is meaningless if you
do not provide us with the disassembly of the function which fails. In
that case that would be rthal_arch_init. Anyway, something is probably
wrong with the registration of the tsc emulation, or with the ipipe_timer.

Please disable CONFIG_SMP. The I-pipe for 3.2.21 does not support
SMP_ON_UP yet, it has only be added to 3.4.
