Unable to boot into nano

Hi,

If you can see the text showing up on the monitor but the UART serial cannot give you info, then it is most likely some setup error on your side for that serial. This serial console can dump log in almost every case except recovery mode and no power status.

Try to open the console before you power up the board. This log is realtime, it cannot trace back if you didn’t catch it. I mean if the log already done printing before you open the console, then you are not able to see any log.

I did have a setup error (had to swap the white and green wire) but still the same issue. I did open minicom before I powered on the unit. Still the same thing…

Try to use other tool like picocom instead of minicom and see if that makes any difference.

Please be aware that this is a basic tool that we are using everyday. So I am 100% sure if you see something on your monitor, then your serial console shall dump the log.

Same thing

I ran picocom -b 115200 -r -l /dev/ttyUSB0
then I plugged power into the device and nothing happens…

Then your cable connection could still be wrong.

Why do you connect the pin on the 40 pin header? the website already showed the uart pin is over here.

Sorry about that , I thought perhaps that was for the 2gb ver.

I got a new error though now

I ran the same command via picocom and nothing happens, I then tried minicom and got this error

minicom: cannot open /dev/ttyusb0: No such file or directory

Are you seriously asking this question? ttyUSB0 and ttyusb0

when I do sudo minicom it won’t let me change it , it just says
minicom: cannot open /dev/ttyusb0: No such file or directory

I then tried changing it via sudo minicom -s

I save it as default but the change does not stick, when I try running it here it also does not show up

However once I close this window it will default back to usb0, vs USB0

Just use picocom. It is more easier to use.

sudo picocom -b 115200 /dev/ttyUSB0

Just ran it , same thing, after I power on the board do I need to do anything ? before or after ?

Nope, it just indicates your connection is still wrong.

Are you using A02 or B01 carrier board or you don’t know what you are using?

BO1 Carrier Board

Just an example of how that log will be like.

This is just an example. Your issue is not same as this guy.

Please make sure your connection matches this.

Jetson Nano J50 Pin 4 (TXD) → Cable RXD (White Wire)
Jetson Nano J50 Pin 3 (RXD) → Cable TXD (Green Wire)
Jetson Nano J50 Pin 7 (GND) → Cable GND (Black Wire)

Make sure the color mapping is correct too. I mean make sure white wire is really RX. Green to TX.

The rest of it is check whether the board really powers up…

Board does power up , I can see the same thing going on when I view it on the monitor

Do you have other jetson or other device to validate your host + this cable really can dump log?

My apologies, my setup was not correct. This cable color coding is different.

Please go to your BSP folder. It is on your host machine with default path ~/nvidia.

Run below command to configure the user account/password as nvidia/nvidia.

sudo ./l4t_create_default_user.sh -u nvidia -p nvidia

And reflash your board agian.

This will bypass the stuck in serial console and let it boot up. We can check the desktop issue after this one gets done.

If you don’t understand what we are doing, then it is the explanation:
In the first boot after each fresh reflash, it requires user to configure the user account and password to proceed the boot up, if you don’t do it, then the boot will get stuck.

For now, we just bypass this configuration and check why the desktop GUI cannot show up on your device.
