Hi,
I am using the AM335X chip. I find that the GPIO has two interrupt number , such as GPIO0A and GPIO0B . What is the difference between two ? Which one should I chouse working in Linus OS . Many thanks!

Hi,
You can use either one. Having two interrupts per GPIO allows you to route two groups of GPIO pins to separate interrupts, respectively separate ISRs servicing them.
