Hi, good morning!
I’ve a BeagleV Fire and I’ve been using it without any problem until recently. The problem I’ve is when I plug the USB Type C cable most of the times does not boot or when boots i get a segment fault.
Somethimes, the beagleV boots correctly, but most of the time it doesn’t. When it boots correctly I see the ethernet interface in my computer and I can do ssh to the device. I tried differente wires but I always get the same thing.
Does anyone knows what’s going on? I haven’t installed anything, nor updated the software. Indeed I haven’t had anyproblem until now.
Thank you so much in advance!
Next I paste the output of the boot process when using the serial port cable:
