I may be doing some work involving a custom U-Boot, and I’m concerned with bricking the board, so I wanted to try “force recovery” mode before I did that.
I intend to use a Raspberry Pi for the host end of this connection.
When I jumper the recovery pins and then reset the Nano, I see this on the raspberry pi:
ubuntu@wrkpi:~$ sudo dmesg -c [21709.178961] usb 1-1.2: new high-speed USB device number 91 using dwc_otg [21709.280035] usb 1-1.2: New USB device found, idVendor=0955, idProduct=7f21, bcdDevice= 1.02 [21709.280057] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [21709.280071] usb 1-1.2: Product: APX [21709.280086] usb 1-1.2: Manufacturer: NVIDIA Corp.
At this point, there is a new device:/dev/bus/usb/001/091
Can I connect to that with microcom? am I supposed to connect in some other way? If microcom, what speed do I choose? Parity?
I haven’t been able to get anything meaningful out of the USB connection.
