Hello, I have installed Jetpack 5.1.2 through the SDKManager on my Orin Nano Devkit, which is mostly working as expected, except I am having some boot issues. When I have an ethernet device plugged into the Jetson, it does not boot.
I have looked at the solution posted here: Boot problem on live device - #7 by linuxdev
However, even when the ethernet device is not plugged in, there is no option to enter the boot menu when I turn on the device. It just takes me straight to the Ubuntu login screen, with no Nvidia logo appearing prior. I also don’t see any boot-related serial output when I connect via a UART serial console with gtkterm - no serial output appears until the Ubuntu login is presented. Here is the entire serial console output after doing a sudo reboot:
Ubuntu 20.04.6 LTS ubuntu ttyGS0
ubuntu login:
In short, I am not seeing any options to enter a boot menu, whether I try to boot and watch the boot process via the display/keyboard, or the serial console. Is there something basic that I am missing?
Can you please help diagnose this issue? Thank you.
