I am experiencing a hardware issue with our custom board which is causing the cpu to get interrupted close to 100000 times per second. I’m trying to track the issue down but I’m having trouble figuring out which pin is the culprit. In /proc/interrupts I found the following interrupt is the one having the problem.
:/home/nvidia# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5
380: 217641179 0 0 0 0 0 tegra-gpio-aon 56 Edge Power
So it is irq 380, with a label “Power” and a number 56. I’m not sure what the number 56 means. Can anyone help me track down which pin is hooked up to this interrupt?
