Hi all,
I am trying to generate pwm on Beagleboard-xm rev C.I followed the
links mentioned below.
[1] http://elinux.org/EBC_Exercise_04_Pulse_Width_Modulation
[2] http://elinux.org/BeagleBoardPinMux
I disabled CONFIG_OMAP_RESET_CLOCKS as mentioned in [2].
But still I get the following error
root@beagleboard:~# ./pwm-demo
0
Bus error
root@beagleboard:~# dmesg | tail -1
[ 174.893035] Unhandled fault: external abort on non-linefetch
(0x1818) at 0x4001f024
Please help me.
