uEnv.txt

This is some kind of a config file on the BBB, found on the external disk beaglebone. The BBB has some virtual capes AKA shields enabled per default, which use some pins, wich actually collide with PWM. So to disable those, add the line:

optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G

to uEnv.txt. Use

cat /sys/devices/bone_capemgr.*/slots

to check the loaded capes, an L means loaded, if your output looks somehow like this:

0: 54:PF--- 
1: 55:PF--- 
2: 56:PF--- 
3: 57:PF--- 
4: ff:P-O-- Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN

then no cape is loaded.
