Hello,
I have been unsuccessful re-flashing the Jetson AGX Thor Dev Kit using SDK Manager. I have also failed to be successful using the l4t_initrd_flash.sh script directly on the host. The host is running Ubuntu 24.04 LTS natively and I am using the supplied USB-C cable plugged into port J81.
I have verified that the Thor is in Recovery Mode using lsusb and seeing “NVIDIA Corp. APX”.
It seems to be getting stuck at the “Making system.img” step in the Flash process.
For reference, this is the command I ran when I tried manually flashing…
sudo ./tools/kernel_flash/l4t_initrd_flash.sh jetson-agx-thor-devkit internal
Hi,
Creating the system.img will take some time. Did you notice the flashing process fail on its own, or did you terminate it manually?
Also, please record the serial console log for our review.
Thanks
I let the Flash process run for a couple of hours before killing it manually.
Here are all of the log files that I exported from SDK Manager.
SDKM_logs_JetPack_7.1_Linux_for_Jetson_AGX_Thor_Developer_Kit_2026-02-11_12-24-01.zip (3.8 MB)
Have there been any updates on this?
It might help to clear out the previous files created during the failed flash
cd ~/nvidia/nvidia_sdk/JetPack_7.1_Linux_JETSON_AGX_THOR_TARGETS/Linux_for_Tegra
sudo rm -rf out
sudo rm -rf unified_flash/output
I finally got it to work using SDK Manager by deleting the auto-generated files and rebooting the laptop.
