Hallo, ich versuche auf einem neuen aktuellen Raspbian Jessie Pixel Image ein fbtft module zu laden genau nach dieser Anleitung: https://github.com/notro/fbtft/wiki 1.) auf /boot/config.txt => das hier aktivieren: dtparam=spi=on (steht zwar nicht in der Anleitung, aber modprobe fbtft bringt sonst error) 2.) sudo modprobe fbtft_device name=adafruit22 3.) dmesg dabei kommt ganz was anderes, hier der Schluss: ################################## [ 12.644214] Bluetooth: BNEP socket layer initialized [ 130.430750] fbtft: module is from the staging directory, the quality is unknown, you have been warned.
