We have just manufactured 100 custom PCB with SC206E SOM chips on them.
One board is showing some faults, and we can’t find any physical problems on the PCB.
Linux is running, but gpioinfo is showing the gpio chip 3 is not present.
Is this likely a SOM hardware issue? Is there some internal setup that can be left behind when we flash an image via QFIL?
I’ve attached the gpioInfo output from a working board, and from the not working one, to show the difference.
The bad board is not able to talk and enumerate our USB devices, so it could be that there are other problems besides the missing gpio chip 3.
Cheers,
Shen
