- If you are using RPi Display module - you need it is necessary to throw a jumper between pins PD24 and PL10
- Add overlay:
sudo armbian-add-overlay sun50i-h6-ili9486-ads7846.dts - Apply Xorg config (/etc/X11/xorg.conf.d/50-tft.conf)
- If touchscreen doesn't work - switch Kernel to "legacy":
sudo apt install linux-image-legacy-sunxi64 - For calibration use this guide: https://bttwiki.com/libinput_calibration.html
