Hi all, so I got this Orin Nano that I haven’t touched since 2024, still on L4T 35.3.x. Tried booting it up again recently and flashed the JetPack 5.1.3 SD card image (JP513-orin-nano-sd-card-image_b29.zip) but it just gets stuck at:
EFI Stub: Exiting Boot Services and Installing Virtual address map...
Stuff I already tried:
- Checked the power supply (DC barrel jack, 9-19V) — seems fine, no issue there
- Re-flashed the SD card with a fresh image (same JP513 image), still same problem
- Tried Force Recovery Mode and it works,
lsusbshows0955:7e19 NVIDIA Corp. APXon host so recovery mode is fine
My setup:
-
Board: Orin Nano Dev Kit
-
JetPack I’m trying to flash: JetPack 5.1.3 (SD card image, build 29)
-
Flash method: SD card image, written from CachyOS (Arch-based Linux)
-
Host OS: CachyOS x86_64
Anyone been through this before? Planning to do full reflash with flash.sh/SDK Manager including QSPI bootloader, but SDK Manager only officially supports Ubuntu — is there a workaround for Arch-based distros, or should I just set up an Ubuntu machine/VM for this?
