PWM on EspressoBIN

Postby jernst » Sun Nov 12, 2017 9:32 pm

Trying to get a PWM work on EspressoBIN, but /sys/class/pwm is empty.

How do I do this?

(It does seem to be enabled in the kernel per kernel config)

I tried a few that are floating around, like this one: https://github.com/MarvellEmbeddedProce ... munity.dts (which is the one Globalscale talks about on their wiki: http://wiki.espressobin.net/tiki-index. ... hlight=dtb ). But nothing changed as far as I can tell.

I think the one you guys ship is more detailed anyway. Unfortunately I don't know enough about either DTBs in general or the EspressoBIN hardware to even come up with some reasonable ideas how to extend this.
