The device I am using is a ReComputer Industrial J2012 which houses a Nvidia Jetson Xavier NX 16GB.
After accessing the boot menu by restarting and holding down shift the screen went black apart from a flashing underscore in the top left corner. When the reset button is pressed, system shows the boot menu again, but any input from the connected keyboard is not registered (ie. esc, F11 and and enter). The system displays the following:
** WARNING: Test Key is used. **
L4TLauncher: Attempting Recovery Boot
EFI stub: Booting Linux Kernal…
EFI stub: Using DTB from configuration table
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Exiting boot services and installing virtual address map…
It then goes back to a black screen and stops outputting anything to the display. I am not an expert in this field and need guidance on how to access the device again.
