HDMI and Power LED dead after using this dtb file #5

Closed jiejiecn closed 9 months ago

jiejiecn commented 10 months ago

After using this dtb file, the power LED is dead. Confused me a lot with the device status.

And there's no signal on HDMI output.

jiejiecn commented 10 months ago

To be clear, the blue LED indicate for the system status is dead. Not the green LED.

Hmm. I will check out of HDMI output signal. You are right about blue LED. If you have some advice let me know.

jiejiecn commented 9 months ago

According to the PCB design, PC13 is the STATUS_LED output.

In the dts file, I can only find the related section around line 483 image

Maybe you can try to remove those lines and have a try.

Thanks, I will test it during weekend.

Yes, LED (blue) is working now.

  1. add OPi.GPIO library at the mangopi mq-quad (see package description part install OPi.GPIO lib)
  2. run script led_mq_quad.py (flashing of LED)
  3. dbd file was updated under your recommendation.

Note: I will be glad for the supporting star.
