I have ubuntu 20.04 on AGX and need 22.04 with jet pack 6,1 because arducam camera Hat will not work on ubuntu 20.04 (tried for weeks).

I have ubuntu 22.04 and sdkmanager on pc (newly installed). I choose the minumum components to flash. I try to start recovery mode by hold pressing the middle button then press release the left button then after 5-10 seconds i release the middle button. I get a light on the AGX and nothing on the screen at first, the sdkmanager cannot detect the AGX. I tried using ethernet cable and alt usb. Neither work. After 20 sec the aGx boots as usual. Not recovery mode. I tried everything. Different usb cables. Ethernet cable. Using the usbC port near left of the pins. I tried the revovery sudo command instead of pressing buttons. Always boots normally instead of recovery mode. Wifi on the AGX quit working today.

Based on the provided context, I’ll address the issues and provide a comprehensive answer.

Issue 1: Ubuntu 2004 on AGX Orin and need to upgrade to Ubuntu 2204 with JetPack 5.1

The user has Ubuntu 2004 on their AGX Orin and wants to upgrade to Ubuntu 2204 with JetPack 5.1 to use the Arducam camera Hat, which is not compatible with Ubuntu 2004.

Issue 2: Unable to enter Recovery Mode on AGX Orin

The user is trying to enter Recovery Mode on their AGX Orin by holding the middle button, pressing and releasing the left button, and then releasing the middle button after 5-10 seconds. However, the device boots normally instead of entering Recovery Mode. The user has tried different USB cables, Ethernet cables, and using the USB-C port near the left of the pins, but nothing works.

Issue 3: SDK Manager unable to detect AGX Orin

The user has installed SDK Manager on their PC and is trying to flash the AGX Orin with the minimum components. However, the SDK Manager is unable to detect the AGX Orin, even when using an Ethernet cable or alternative USB cables.

Comparison with Force Recovery Mode (Concept)

The user’s attempt to enter Recovery Mode by holding the middle button, pressing and releasing the left button, and then releasing the middle button after 5-10 seconds is similar to the Force Recovery Mode (Concept) described in the context. However, the user’s method is not working, and the device boots normally instead.

Possible Solution

To enter Recovery Mode on the AGX Orin, the user can try using the sudo command instead of pressing buttons. The exact command is not specified in the context, but it might be something like sudo reboot recovery. This command can be executed on the AGX Orin terminal or through the SDK Manager on the PC.

If the user is still unable to enter Recovery Mode, they can try using the build_l4t_bup.sh tool to build a BUP image for the AGX Orin carrier board. This tool can be used to generate a Bootloader Update Payload (BUP) image, which can be used to recover the device.

Additional Information

The user’s WiFi connection on the AGX Orin has stopped working, which might be related to the issues they are experiencing. It is recommended to troubleshoot the WiFi connection separately to ensure it is working properly.

In summary, the user is experiencing issues with upgrading their AGX Orin to Ubuntu 2204 with JetPack 5.1, entering Recovery Mode, and detecting the device with SDK Manager. Possible solutions include using the sudo command to enter Recovery Mode, building a BUP image using the build_l4t_bup.sh tool, and troubleshooting the WiFi connection.

Below is Cline AI after trying to assist and it comes to the conclusion after 2 days trying to find solutions, and the hardware should be working. It does scan for routers but the Ubuntu GUI shows no wifi option or wifi icons and nothing in hte settings to activate Wifi. Fan works during boot but not when booted. USBs seems to be found but do not work. Ehernet same thing. So no way of connecting the PC: recovery mode isnt working. Tried with the force recovery command as well as the button tricks. So im in a moment 22. The Cline AI at this stage says I have onl 1 option. SD card flash but when I search this it says that AGX cannot be flashed with SD card. How is this situation even possible?

THE REALITY CHECK:

Your AGX Orin has severe Ubuntu 20.04 corruption:

  • ✅ Hardware works (fan, USB keyboard, ethernet lights, WiFi scan)
  • ❌ Software completely broken (NetworkManager, drivers, system tools)

FINAL RECOMMENDATION:

You need to reflash to Ubuntu 22.04. The system is too corrupted to fix with configuration changes.

Options:

  1. Buy $10 SD card - guaranteed solution
  2. Try USB recovery one more time with different cable
  3. Accept broken system until you can get SD card

THE TRUTH:

Your hardware is fine, but Ubuntu 20.04 is beyond repair. Every network command fails silently, indicating deep system corruption.

The fastest solution is still buying an SD card and flashing Ubuntu 22.04. Everything will work perfectly after that.

Perfect! This screenshot shows exactly what’s happening:

ANALYSIS OF YOUR SCREENSHOT:

What’s Working:

  • ✅ Ethernet interface exists - eth0 shows UP state
  • ✅ Basic network stack - interfaces detected
  • ✅ WiFi hardware detected - shows “netplan-wlan0-ASUS Nere” connection

What’s Broken:

  • ❌ No IP address assigned - eth0 has no inet address
  • ❌ No internet connectivity - “Network is unreachable”
  • ❌ NetworkManager corrupted - commands fail silently
  • ❌ Missing basic commands - “just: command not found”

THE SMOKING GUN:

Your AGX Orin shows a WiFi connection name “netplan-wlan0-ASUS Nere” in the title bar! This means:

  • WiFi hardware works
  • WiFi can see networks
  • But can’t connect due to software corruption

FINAL DIAGNOSIS:

Hardware Status: ✅ PERFECT

  • Fan spins at boot
  • USB keyboard works
  • Ethernet lights work
  • WiFi scans networks

Software Status: ❌ COMPLETELY BROKEN

  • Ubuntu 20.04 is severely corrupted
  • NetworkManager non-functional
  • Missing system commands
  • No network connectivity possible

CONCLUSION:

Your AGX Orin hardware is 100% functional. The only solution is reflashing to Ubuntu 22.04.

You MUST buy an SD card ($10) or get a UART cable ($5). There’s no software fix for this level of corruption.

Ready to get an SD card and fix this properly?

Hi,

You could use lsusb to check whether the device in recovery mode.
Could you put device in recovery mode again and check?

Thanks
