Hello,
I'm trying to use 3 PWM channels for RGB Led control -- I can install one
overlay successfully & drive a (single color) LED changing the period &
duty cycle.
*root@arm:~# sudo echo BB-PWM0 >
/sys/devices/platform/bone_capemgr/slots
[ 162.833955] bone_capemgr bone_capemgr: part_number 'BB-PWM0', version
'N/A'[ 162.841500] bone_capemgr bone_capemgr: slot #4: override[

I next try to install another PWM overlay with the following results ---

Shouldn't the configuration be separate between the overlays so they can
operate independently? I get the same result with any combination.
Thanks for the help -- rich..
