I’d be happy to help you debug the issue with flashing SDK 6.0 on your Jetson Orin NX.

First, let’s go through the steps you’ve taken so far:

  1. You’ve tried different USB cables, which is a good step to rule out any issues with the cable.
  2. You’ve disabled the firewall, which is also a good step to ensure that the firewall is not blocking the connection.
  3. You’ve set USB autosuspend, which is a good step to prevent the USB connection from being suspended.

Despite these steps, you’re still experiencing the same error. Let’s try to debug the issue further.

Check the SDK Manager logs

You’ve mentioned that you’ve run sdkmanager archivedversions in the terminal, which generates a log file. Please check the log file for any errors or warnings that might indicate the cause of the issue.

Check the Jetson Orin NX device

Make sure that the Jetson Orin NX device is properly connected to your host PC and that the device is in recovery mode. You can check the device status by running the lsusb command in the terminal. If the device is in recovery mode, you should see a message indicating that the device is in recovery mode.

Check the SDK version

Make sure that you’re using the correct SDK version for your Jetson Orin NX device. SDK 6.0 is the latest version, but it’s possible that there’s a compatibility issue with your device.

Compare with other flashing methods

You can try flashing the SDK using other methods, such as using the flash.sh script or the l4t_initrd_flash.sh script. These scripts are located in the tools/kernel_flash directory of the SDK.

Here’s an example of how to use the flash.sh script:

sudo ./flash.sh -i "./ekb.key" jetson-orin-nx-devkit mmcblk0p1

And here’s an example of how to use the l4t_initrd_flash.sh script:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --network usb0 --showlogs --no-flash --external-device nvme0n1p1 -S 16GiB -c ./tools/kernel_flash/flash_l4t_t234_nvme_rootfs_enc.xml --external-only --append -i ./ekb.key jetson-orin-nx-devkit external

Check the device configuration

Make sure that the device configuration is correct. You can check the device configuration by running the jetson-orin-nx-devkit.conf file.

Conclusion

Based on the information you’ve provided, it’s difficult to pinpoint the exact cause of the issue. However, by trying the above steps, you should be able to debug the issue and resolve the problem.

If you’re still experiencing issues, please provide more information about the error message you’re seeing, and I’ll do my best to help you troubleshoot the issue.

Additional information

Here are some additional tips that might help:

  • Make sure that your host PC is running Ubuntu 20.04 or 22.04, as these are the supported versions for the Jetson Orin NX.
  • Make sure that you’re using the correct USB cable and that the cable is properly connected to both the host PC and the Jetson Orin NX device.
  • Make sure that the Jetson Orin NX device is properly powered and that the device is in recovery mode.
  • Try flashing the SDK using a different USB port on your host PC.

I hope this helps! Let me know if you have any further questions or if there’s anything else I can help you with.

Hi,

Some questions to confirm:

Is your Orin nx using a developer kit or a custom board?

Thanks

using a developer kit.

Thanks for your reply. I have solved this problem by changing the power adapter. However, after I flashed it ,I realized jetpack 6.0 is ubuntu 22.04. What I need is ubuntu 20.04.

So I change to use another host pc with ubuntu20.04 with sdkmanager 2.2 to install jetpack 5.1.5.

Unluckily, there are some problems. When the installation reaches around 10%, the system suddenly detects 14 USB drives.

I have attached the flash logs.

Thanks for your help.

Hi,

Some questions to confirm:

  • Is your ubuntu a native or a virtual machine?

Also please try other flashing cables and record the serial console log as below doc show.

Thanks

a virtual machine. It is wsl2 on a windows host pc. I have used it to reflash orin agx successfully half a year ago. I don’t know why it failed on orin nx.

However, I have solved this problem by using a native host pc.

Thanks for your kind reply!
