I wrote a RTOS for the TS7250 a while back as a project. I remember having
some difficulties with the FIQ but the regular IRQ's worked fine.
Your post looks kind of odd, (not belonging to any topic as it seems), so I
don't know what exactly you are asking for but if you want I cand send you
some code for a IRQ handler.
