I’ve downloaded and flashed nv-jetson-nano-sd-card-image-r32.3.1.zip to an SD card and then tried to boot my Jetson Nano from this image with a cable connected to TX, RX and GND on the 6 pin header (J44) and the 40 pin header (J41). I’ve also tried using the microUSB port (J28). That would be ttyS0, ttyTHS1, and ttyGS0. On ttyS0 I can see the boot up console output. On the others I sometimes see nothing and sometimes get a log in prompt.
At the end of the console boot up output I see the following message:
Please complete system configuration setup on the serial port provided by Jetson's USB device mode connection. e.g. /dev/ttyACMx where x can 0, 1, 2 etc.
How exactly am I supposed to complete the system configuration when I can’t log in?
Also, sometimes I get this message again and again when I connected, and sometimes I don’t:
cu: Got hangup signal Disconnected.
This hangup signal occurs on all 3 of the tty serial ports.
Here is an example:
administratoraccount@Terjes-New-MacBook-Pro-750m ~ % sudo cu -s 115200 -l /dev/cu.usbmodem14225190414253 Connected. cu: Got hangup signal Disconnected. administratoraccount@Terjes-New-MacBook-Pro-750m ~ %
I have a jumper on J48, and am using the J25 Power Jack for power.
