Hi
We are triggering an interrupt on GPIO0, successfully and the ISR is
being run. It is empty, that is it simply returns. We are observing /
proc/interrupts to see the increment.
The problem is that when we hook the DVEVM up to a (4-5Mhz) source
rather than a simple switch we lose all terminal access, SSH, telnet
and so on. The board appears to have hung. But when we remove the
source from GPIO0 the terminal returns. We see a good number of
interrupts in /proc/interrupts but it appears that the source at this
rate (~5Mhz) is far too much for the GPIO/ISR/CPU.
Should this be expected?
Nick
