Public bug reported:
I'm trying to use a touch screen that needs a goodix touch driver. I can
see in the overlays folder that there is a goodix.dtbo file, so I assume
the kernel has support for this device.
I downloaded Ubuntu Mate (32 bit) for raspberry pi and added these two
lines in config.txt in /boot to enable the touch screen (which worked):
dtoverlay=i2c1-bcm2708,sda1_pin=44,scl1_pin=45,pin_func=6
dtoverlay=goodix,interrupt=42,reset=43
I tried doing the same on ubuntu core and it throws this error when
booting up:
[ 1.974002] pinctrl-bcm2835 3f200000.gpio: pin gpio0 already requested by leds;
cannot claim for 3f205000.i2c
[ 1.984067] pinctrl-bcm2835 3f200000.gpio: pin-0 (3f205000.i2c) status -22
[ 1.991045] pinctrl-bcm2835 3f200000.gpio: could not request pin 0 (gpio0) from
group gpio0 on device pinctrl-bcm2835
[ 2.001897] i2c-bcm2835 3f205000.i2c: Error applying setting, reverse things
back
