i use the pocketbeagle board.

and set pin p2_1 to analogwrite

b.pinMode(pin, b.ANALOG_OUTPUT, );
b.analogWrite(pin, 1, 2000, printJSON)

sadly it ends in this error:

{"err":"error updating PWM freq and value: undefined, Error: ENOENT: no such file or directory, open 'undefined/period'"}

same error in the playground.
i really need analog write. do you have any suggestions how i can use it?

This is going to require a kernel update as I've got the other fixes in. I believe @RobertCNelson will do the kernel update soon. See #156.
