Hey I see you are one of the few that seem to be using OPi Z2 to run octoprint. Have you had any luck finding and running any GPio plugins? I want to read a BME680 and control a fan based on it's readings but all the RPi.GPIO plugins I have found fail to install in Octoprint probably because of the different pin configs.

Hi,

Just wanted to add that using the overlays setting in orangepiDev.txt to enable I2C was unnecessary as the SCK and SDA pins already appear in /dev:

$ ll /dev/i2c-*
crw-rw---- 1 root i2c 89, 0 Apr 28 23:53 /dev/i2c-0
crw-rw---- 1 root i2c 89, 1 Apr 28 23:53 /dev/i2c-1

Adding the overlays parameter meant sudo i2cdetect -y 0 could not find the expected -0 and -1 pins.

There is one I2C error I can't resolve (yet) though:

$ dmesg | grep i2c
[    1.263757] i2c_dev: i2c /dev entries driver
[    2.712772] mv64xxx_i2c 7081400.i2c: can't get pinctrl, bus recovery not supported

[    2.796056] axp20x-i2c 0-0036: AXP20X driver loaded

Thanks for the notes.
