HI Honey,
We are facing the same problem
We have ported JB 4.2.p1 with kernel 3.4 onto our custom board having omap4430. We have connected an interrupt pin of a device on our board to gpi 80 pin of omap. The device is configured to send out interrupts to the omap gpi 80 at every 10ms i.e 100hz pulse train. We toggled another gpio 3 pin of omap on receiving every interrupt pulse as mentioned above in the interrupt handler function of our device . We noticed on probing that the gpio 3 did not toggle consistently at 10ms, and it skipped a few pulses, and at times the delay was as high as 200ms.
However on repeating the same experiment n ics with kernel 3.0.4 we noticed that gpio 3 toggeled consistently at 10ms without any issues.
We have to correct this inconsistent behaviour and the interrupt latency. Could you provide suggestions on this?
Thank You
Prakash
