johnrego Posted March 6, 2017 Share Posted March 6, 2017 When it starts the Armbian logo appears, then the hdmi signal is cut off and BPI-M2 no longer plays video. This is mine current situation Link to comment Share on other sites More sharing options...

Igor Posted March 7, 2017 Share Posted March 7, 2017 Bingo! That works Safe to add permanently? Link to comment Share on other sites More sharing options...
zador.blood.stained Posted March 7, 2017 Share Posted March 7, 2017 Just now, Igor said: Bingo! That works It's not exactly "bingo", it means that something is still wrong with simplefb node or clocks definitions. Maybe you should ask wens on IRC about this since he made the patch I linked previously. Link to comment Share on other sites More sharing options...
palmatown Posted March 7, 2017 Share Posted March 7, 2017 I am hitting the same bug on the M2. This was working about a month ago and at some point stopped so I loaded a different image from BPI site with no problems. Adjusting "clk_ignore_unused" in kernel command line is something I haven't done before (based on a quick I search I did). Anyone have a link I could use to see how to do this? I'll try anything Thanks. Link to comment Share on other sites More sharing options...
