SCM does not boot after change to config.txt

Hi.

Issue and potentially useful information.

I changed the config.txt file of the SCM, more precicely I commented out the line

dtoverlay=dwc2,dr_mode=host

in both the [cm4] and [cm5] section. After restarting the device, I get constant rapid blinking.

The following error message is visible

Other information

  • I use the waveshare CM4-IO-WIRELESS-BASE for my SCM
  • I tried it out with a power supply with 5V 3A and 12V 5A. Both returned the same messages and generally have the same behavior.
  • Unfortunately, I did not read the documentation before and did not update the manifest.

Questions.

  • I can’t interact with the SCM currently. When I plug in a keyboard, I can’t fix anything. Is there a way for me to change the config.txt?
  • Should I have rehashed the config.txt?
  • How to fix this issue? It would be nice, if I could access the config.txt somehow; I am not sure whether it is possible.

Thanks in advance :smiley:
