RTEMS on Beaglebone Black

Have you got interrupts working on the GPIOs. Also, do you have any
sample of reading and writing to GPIO. I need to see whether it is going
to be fast enough,
I ran a program (on linux) on beagle that used registers basically
toggling an output. EG
It toggled at rate of just under 1Mhz, and what was just doing a while 1
loop. I did not look even look at interrupts there and did nothing else
- I didn't even do any reads of GPIO.
I want to get interrupts happening at 1.56Mhz (preferable) and read 14
GPOI, sbut I could go to half the rate by reducing my sample rate. The
beagle runs at 1Ghz, so I think it should be able to handle it.
