LePotato GPIO Support

Hi folks,

im using the LibreComputer AML-S905X-CC (LePotato) board with the latest official libreelec alpha build.

The device performs very well and now i would like to use the GPIO pins for my DIY ambilight leds. The Hyperion software installs fine and i have to configure the "device" for the led output in the software. Unfortunately the GPIO headers seems to work a little bit different as by the raspberry pi and the standard "/dev/spidev0.0" device doesnt exist.

I searched a while about the GPIO usage of the LePotato and found this google document: edit#slide=id.g3274ff538d_0_45

LibreComputer recommend to use in linux the "/dev/gpiochip" device for GPIO header usage. Unfortunately this device doesnt exist also in LE.

So...im little bit confused and dont know how to proceed in this case. Does anybody knows more about the GPIO header from the LePotato? Or maybe how to configure Hyperion to get it work with the Potato?

Best regards, WeeZel

That document feels recent, which means it's probably written for the mainline kernel not the ageing fossil that's in current LE release images. Have a play with the balbes150 releases with a 4.19 kernel. Things are a little experimental still, but the GPIO stuff is likely work better.
