Issue with Jetson nano 2G boot up for the first time

Hi , I’m trying to bootup my Jestson nano 2G unit for the first time. I see nvidia logo and the screen is stuck there. Attaching the boot log for more details. I’m booting via SD card and downloaded the 2G version of the image from

I’ve unzipped the file contents and copied them using BalenaEtcher onto a UHS-1 64gb sandisk microsd card. Pls let me know what am I missing here. Thanks.

The SD card models of Jetsons have QSPI memory containing boot content. That has to be a release version compatible with the SD card release. Most likely you will need to flash the module itself with an Ubuntu 18.04 host PC and JetPack/SDK Mananger. See:
https://developer.nvidia.com/embedded/jetpack-archive

Hi linuxdev, thanks for responding. I’m new to this platform. I’ve installed the SDK Manager on ubuntu machine. When I connect my Jetson nano via microusb and run thru the steps as listed in the SDK manager still doesn’t detect the device. Can you pls share how to flash the sd card modules? Also, is there a way to identify if jetson nano went into recovery mode?
I’ve checked dmesg and also lsusb for any NVIDIA devices, but did not find any.

If the correct USB cable is connected (it uses a micro-B USB cable on the micro-OTG USB port), and if the Jetson is in recovery mode, then SDKM should detect the Jetson. Recovery mode occurs if the recovery pin is shorted to ground during the moment power is applied, or if the pin is shorted to ground when the power is reset. There is no need to hold the recovery pin shorted to ground after power up or power cycle. If lsusb still fails, then something has gone wrong (perhaps it is the wrong cable, or perhaps it isn’t really in recovery mode).

One thing to test is that if you think the Jetson really is in recovery mode, then monitor “dmesg --follow” on the host PC and either plug in or replug the cable and see what new log messages come up. Post what you get.

Note that you can still flash SD cards separately so long as it is from a release version compatible with what was flashed to the module’s QSPI memory.

Note: VMs typically fail like this due to improper setup of USB passthrough.

I’m using a standalone Ubuntu 18.04 machine. I tried swapping multiple USB cables. I don’t observe any new messages on dmesg when putting the device in recovery mode or in general plugging/re-plugging the micro USB cable to jetson nano. Any idea which version of sd card image is compatible with the modules on my qspi? Does the serial log attached above give any cues as to what’s going wrong?

I have no way of knowing which release your QSPI is currently at.

The lack of any message with plug/unplug tends to indicate a hardware error if the Jetson was put into recovery mode. If you are using a “charger” cable rather than one provided, then this could be the problem, but since you tried multiple cables (and I assume watched logs from dmesg for each) and this did not show anything at all, then I am thinking it is hardware failure.

Someone from NVIDIA may be able to spot something in the log, but I can’t see any “simple” cause. The same advice would probably be repeated though, to try to flash. If flash is not possible it may require RMA.

  1. For any jetson nano issue, if you see it got stuck in bootloader, stop trying sdcard image. Just try to flash with sdkmanager.

  2. To flash with sdkmanager, you need to put the board into recovery mode.

  3. In this page, please set “Pre-config” and manual config.

Hi WayneWWW, I’m trying to put the board in recovery mode by connecting Pin 9 FC REC and Pin 10 GND, booting up, and removing it after a few seconds. But the board is not going into recovery mode. Checked dmesg and lsub to detect any NVIDIA USB port messages, but I see none. The image I shared above is what exactly I’m using with the configs you mentioned. I think the core issue here is I’m not able to put my unit into recovery mode. I need assistance with it. Also, can u take a look at the serial log I pasted above and let me know if there are any cues on what is going wrong? Is there a different way to put the board in recovery mode?

Hi,

  1. Remove the power cable from your jetson.

  2. Plug the FC REC +GND jumper. Do not remove it. Plug the power cable back.

  3. Check the lsusb on your host. (also with micro usb cable connected to jetson).

Still see nothing. No new Device ID pop up

How many jetson do you have on your side? And how many of them cannot enter recovery mode?

I only have one board with me.

Is your host machine a VM? Does you micro usb cable have data line but not only power line?

I’ve a stand-alone Ubuntu. Looks like my usb cable has a faulty data line, have re-soldered it. Able to put the unit in recovery mode 😀 Will continue flashing using the sdkmanager. Thanks for the inputs WayneWWW.

Good evening,
I am having the same type of issue with a Jetson Nano 2GB.
I have tried booting via the SD card with the 461 image and the screen got stuck at the nVidia logo.
Then I switched to using SDKmanager. I am running Ubuntu 18.04 on a host PC. I have put the board in Forced Recovery mode. The flashing process started and it works for a while but then it fails. I have tried numerous times, same result.
I have saved the log, I will attach it here.

Hi,

Please try multiple times and see if it always got stuck. If so, please

  1. Make sure your sdcard size is large enough. I would suggest at least 32GB.

  2. Dump the serial log as Jetson Nano Style - Serial Console - JetsonHacks when the flash starts.

Also, make sure the usb is not disconnected during flash and host is not VM.

Hi Wayne,
I confirm that:
1)I have tried multiple times with the same result.
2) The sd card size is 64GB.
3) The host is NOT a VM.
4) The USB is NOT disconnected during flash.

I will work on the serial log and post it as soon as I have results.

Thank you for helping us.

Hi Wayne,
On my side, the issue has been resolved. I have tried flashing again, this time with a different micro-USB cable and the flashing process was completed.
Thanks again.
