Looks like this is the most recent thread on GPIO Interrupts. What's the current status on GPIO interrupt support on the Omega2?
what are the typical latencies associated with the sysfs method?
are there any advantages for the kmod-gpio-irq path?
if so, is there a reliable way to use kmod-gpio-irq on the Omega2 or is it likely to end in the dead-ends reported in this thread?
@Boken-Lin Thanks - had already found this. I think some of my issues to date have been to do with my mistakes in building kernel code using the OenWRT cross compilation - I think I had some settings wrong. Am in the process of trying again with git://git.openwrt.org/15.05/openwrt.git - will let you know how things go.
