Duo S bricked - no RNDIS connection on boot up #24

Open UQuark opened 2 weeks ago

UQuark commented 2 weeks ago

Hi. I would very like to provide more info, but I've got absolutely no clue how to get any kind of log in this brick state.

Previously everything worked with a stock buildroot image as well as self-built buildroot image I dd'ed latest .img file onto an SD card and connected Duo S to my PC After more than 5 minutes, no network connection appeared.

The only thing I noticed is that when I connect Duo S to my PC WITHOUT an SD card, a "usb connected" message appears in dmesg. When SD card with debian is present, no dmesg events are reported whatsoever.

Could you please provide some guidance on how to debug such issues

Fishwaldo commented 2 weeks ago

You will need to connect a serial terminal to the UART to see the boot up messages and from there we can determine what went wrong.

UQuark commented 2 weeks ago

Hi again. I connected it via UART as you told and when I used minicom - it suddenly started initializing and the network connection appeared.

I will perform some more tests to pinpoint the issue.

Maybe it is due to a few resets I've done during UART setup.

UQuark commented 2 weeks ago

Can confirm - resetting the device is a workaround. Still no clue why.

There you go, managed to pull out logs from a fresh boot.

After I hit reset, I can see it boots up properly
