Ah, that is good news, at least now we have a clue. Note that it could
also mean that the timer has ticked, but the irq is not generated for
another reason. I think you should dump all the timer registers, and see
if anything is wrong by decoding their values with the datasheet.

A quick test also, assuming that the write to the MX3_TSTAT regiter in
gpt_irq_acknowledge may be posted, try rereading the register after
writing it.

If you need someone's help, you need to give access to your board to
that person or company. Because indirect debugging is really
inefficient: look at how many mails I had to send you over how much time
to get you to do what anybody with xenomai experience would have done in
just a few hours.
