Hi shai.j.dickman,
Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?
Could you share the full log as file here for further check?
You can also refer to PXE Setup for Jetson AGX Orin with Jetpack 6.0 - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums to setup PXE for Jetson device.
