I need some help, I can’t get my Waveshare 7.9 DSI touchscreen to work, it stays dark. I installed ‘touchscreen’ and ‘now playing’ plugg-inns in Volumio, but noting. The dsi- interface board has 5 V (5.2V to be exact) power and shows a green blinking led.(see movie) The 1280x400 setting works on my iPad. DAC plays superb, so does the filterboard op top.
Could you please help me out?
