I tried to boot the Nano dev kit from SD card which has the boot image from this site. Once it powered on, an error message was displayed. After I dismissed the error message, the boot process continued, but hang somewhere and the display went blank forever.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Hi tingzhao,

Please help to provide the serial console log for further check.
You could refer to the following instruction to capture that.
Jetson Nano Style - Serial Console

Or you could refer to the following instruction to flash the board with SDK Manager
Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation

Hello,

I powered the board from J25 power jack. The connect the board Micro-USB to the Mac Book with USB cable.

When I use screen command below to connect to the board, it asks for login credential as shown in attached screenshot.

$ screen /dev/cu.usbmodem14216210560373 115200

Please let me know what credential should I use?

I think that is the username/password which should be configured in the first time boot up in System Configurtaion.

For your current issue, we would suggest to re-flash the board with SDK Manager, and you could set username/password in pre-config.

Hi Mike,

It was very nice talked to you and Nvidia team. This is the Jetson Nano issue I talked about yesterday. It is a new dev kit (it is a replacement of broken one). But it can’t be booted since I having it. Could you please help me on it.

Thank you!

Ting

The attached screenshot here is the output from dev kit after power on, the system is just hanging there without any response.

Because support team asked me to try SDK manager, I tried but get this error. This error seems not related to the Jetson Nano issue I have but could you please help me to understand what this message mean ( The network connection was working because I verified that I can login to https://developer.nvidia.com/user from the same system).

Have you tried to re-flash the board with SDK Manager already and the issue still exists?

You could also provide the serial console log for further check.

Hello,

For answering your questions:

Have you tried to re-flash the board with SDK Manager already and the issue still exists?

Any serial console log?

Hello,

As I responded in previous email, I can’t get console log, and waiting for your helps.

Thanks,

Ting

Hi Ting,

Are you able to use browser to check what you said?
Your previous reply replied nothing. What is the exact problem here? Don’t know how to dump log?

Hello,

In my response of Mar 30, I explained that that the “screen” command not working, and there is a screen shot attached. Please take a look.

Regards,

Ting

Hi Ting,

  1. You are not dumping the the log we want you to dump. Please follow this page.
    https://jetsonhacks.com/2019/04/19/jetson-nano-serial-console/
    Definitely not micro usb port… if you are using micro usb, then it is wrong…

  2. Please try to run sdkmanager again. If you still get oops, we need to check what happened to your account.

Hello,

I will try to collect the log later since I need to order the debugging cable.

Regards to the SDK manager error, I am still getting the same error as I shown in the attached screenshot here. It happened around 1:45PM EDT today if you need to time.

To the attention of NVIDIA team, I am having the same issue on the 2GB Nano Board with regular off the shelf carrier board. I am trying these on a brand new board. Here are the steps:

  1. I flashed this image: https://developer.nvidia.com/jetson-nano-2gb-sd-card-image. (128GB, 64GB, 32GB SD cards, they all show same symptoms)
  2. I power up the unit, “Installation Failed” window comes up as tingzhao shows in first message.
  3. Unit goes back to booting.
  4. Windowing system shows up with options “other”, username and password.
  5. If I hook up a console to UART port, it is asking me username and password.

Now, the weirdness is, I did not initialize this device, so I did not assign a username and password. It feels like, I know it doesn’t make sense but, somebody put an initialized image to sd-card-image link above. Would it make sense to double-check those images and make sure they are the correct ones.

@e_altan it is known issue to me. You cannot rely on sdcard image. Need to reflash the board with sdkmanager. It would work after reflash.

Hello,

Do you have any progress regards to why SDK manager not working for me?

Ting

Hello,

Here is the output from debug console of the Nano dev kit.

It ends at requesting login credentials, which I don’t have.

From the log, it seems your board boot up successfully and ready to log-in.
The username/password for log-in was configured at the first boot of system configuration (oem-config).
