I am posting here to seek assistance with a booting issue I am experiencing with my NVIDIA Jetson AGX Orin embedded device.
Issue Summary: Yesterday, I accidentally unplugged the power cable without proper shutdown. Since then, my Jetson device is unable to boot into Ubuntu. Upon startup, it displays the NVIDIA screen with the message “Warning: Test key is used, EFI booting Linux kernel, using DTB from configuration table, loaded inLtrd from Linux_EFI_inItrd_media_guid device path,” and then goes into sleep mode without starting Ubuntu.
Steps Taken:
Checked Power Supply: Ensured the device is receiving adequate power.
Monitor Connection: Verified correct monitor connection and settings.
Reseated Connectors: Disconnected and reconnected all cables.
Attempted Forced Reboot: 1. Press and hold down the Force Recovery button, then Press and hold down the Reset button, then release both button. (tried in both on and off).
Inspected Hardware Connections: Ensured all connections are secure.
Attempted Remote Access: Unable to remotely access the system.
I only have windows laptop therefore I was unable to boot with sdk manager, would also like to if there is possiblity to do without host machine.
Background: The issue happens only after an unintended power loss. The device was working fine before this incident.
Request for Assistance: I am seeking guidance on how to resolve this booting issue. If possible, could you provide step-by-step instructions or suggestions for troubleshooting? Additionally, if there are specific logs or diagnostics that could help identify the problem, please advise on how to access them.
I appreciate your time and assistance in resolving this matter. Please let me know if there is any additional information you require.
What you see is actually normal for the very first start of boot. What you need is a serial console boot log. You could use PuTTY from Windows to get that boot log. Setting is 115200 8N1 (you’ll have to figure out which port it is when you plug in the correct USB…which happens to be set up for serial console if you use the correct connector…the one to the left of the 40-pin header on the AGX Orin).
I identified the COM port associated with my Jetson device as COM6 in the Device Manager. However, when attempting to connect PuTTY to this COM port using the recommended settings (115200 8N1), the connection is unsuccessful.
Steps Taken:
Checked COM Port: Confirmed that the COM port associated with the Jetson device is COM6.
PuTTY Configuration: Configured PuTTY with the correct COM port (COM6), speed (115200), and other recommended settings.
Connection Attempt: Attempted to connect PuTTY to the Jetson device using the configured settings.
Observations: Despite following the steps meticulously, the connection to the Jetson device using PuTTY is not successful.
Is there a specific troubleshooting step I may have overlooked, or are there alternative methods to verify the serial line connection?
There would still be something wrong with the logs since the logs would likely also include the text content you saw in the screenshot. I agree that it looks like it should work as you’ve set it up, but something still is not working for serial console, and serial console is probably the most reliable tool there is (this is one of the reasons I have frustrations with working with Windows on this…it’s hard to “know” certain failures are actually the Jetson and not a quirk of Windows).
Unfortunately, the next step is usually to attempt flashing. Flashing requires a Linux host PC. Ubuntu 20 would be advisable (18 might work, but I suspect that when the next release for flashing comes out within about a month, that 18 won’t work when in the GUI for flashing). Some people try a VM, but I recommend against that since VMs tend to have USB issues and it is up to the end user to debug the USB problems.
