Jetson Orin Notes

Notes on programming/interfacing with Jetson Orin hardware.

Upgrading AGX to Jetson Linux 36.3

BSP approach (avoids SDK Manager)

• Requires Ubuntu 22.04. Very unhappy to work on Gentoo.
• Requires Intel/AMD 64bit CPU.
• Download "Driver Package (BSP)" from here
• Unpack (as root, get used to doing most of this as root), preserving privileges
  • tar xjpf ...
• Download "Sample Root Filesystem"
• Unpack (as root..) into rootfs directory inside of the BSP archive above.
• Run sudo ./tools/l4t_flash_prerequisites.sh
• Run ./apply_binaries.sh from the BSP
  • Note: If apply_binaries (or frankly, anything, this is brittle) fails, remove and recreate rootfs - the OS might be left in an unbootable state.
• Reboot AGX into "Recovery Mode" - hold the recovery button and reset button, release simultaneously ((sic) reset first?)
• Connect USB-C cable to the debug port ("front" USB-c)
• Nvidia AGX device should appear in the lsusb under NVIDIA CORP. APX
• Run ./flash.sh Different options for different usecases(https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/IN/QuickStart.html#in-quickstart)

Jetson AGX Orin Developer Kit (eMMC):

$ sudo ./flash.sh jetson-agx-orin-devkit internal

• Watch for few minutes, typically it crashes early, then go for lunch.

Upgrading Nano to Jetson Linux 36.3

Buildroot approach (avoids SDK Manager)

sudo mkfs.ext4 /dev/sdb sudo umount /dev/sdb lsblk -f

• Transfer rootfs onto sd card

sudo dd if=/home/dpsh/Downloads/rootfs.ext4 of=/dev/sdc1 bs=1M status=progress

• Make sure the data was transferred to SD/NVMe
