Hi,
Trying to enable timer4 in Beaglebone black 3.8.13-bone79 following the thread:
https://e2e.ti.com/support/arm/sitara_arm/f/791/t/415079
where a platform driver is created to configure the dmtimer/timer4. DT is used to set output pin for timer4.
My problem is I couldn’t seem to set the pinmux for timer4. And after insmod <timer_driver>.ko, nothing seems to happen, the /proc/interrupt shows no interrupt no allocated.
Any idea what possibly went wrong?
Thanks!
