Other Parts Discussed in Thread: AM3359
We are building an application that would use GPIO interrupts. I would like to know if there is a way to handle IRQs in Linux userspace. I've read the documentation, that GPIOs can be used as interrupt inputs for up to two inputs per bank. Some forum posts claim that we have to write a kernel module for that. But since that seems quite simple for the ones who know what to do I hope there already exists a module we might be able to use. How would you handle interrupts in an application?
We are using Phytec phyCORE AM335X with TI AM3359 ARM processor.
