Ensure that you DON'T have pitft support enabled when using this touchscreen! (PiTFT uses /dev/fb1, which isn't the case for the official toucscreen). 2. Build for example 'core-image-sato' 3. Add: echo "dtoverlay=rpi-ft5406" >> /path/to/sdcard/boot/config.txt ...and you are done. Like stated in the commit msg this is just an enabler for being able to configure rpi-ft5406. When I have time I will send the complete solution for this, perhaps a good idea is to do like a MACHINE_FEATURES as well, to make it look similar to the PiTFT's usage?
