IMX6Q HDMI hot-plug problem

Question asked by Jimmy Li on Dec 14, 2017


     I meet with a problem which is described below.

     IMX6Q object board connects with displayer by standard HDMI interface(19 pins). Firstly, the displayer can display normally; But after hot-plug some times, the displayer displays "no signal"; Then hot-plug again, the displayer may return to normal.

     When the problem happened, the log showed that EDID read was right and the differential lines had output signal.
