Hi,
Raspberry Pi on Xenomai v2.6.2.1 passes all the regression tests
except for the xddp_test. The test fails with "FAILURE bind: Address
already in use".
How do I resolve this issue?
Hi,
do you have the same issue with Xenomai from git repository?

Hello Gilles,
I have restarted from scratch and the issue seemed to have resolved itself. I
have no clue why it initially failed.
Thanks!

I have found the cause.
If the module xeno_klat is loaded, xddp_test fails.
It looks like both the kernel latency and xddp tests do not cope well
together, with respect to the message pipe number they want to use. The
patch below works around the issue, but xddp_test should rather be fixed
to use the XDDP port auto-selection, like klat already does.
