Reproducible procedure for preparing a Windows 11 host with WSL2, forwarding a Jetson recovery-mode USB device into Ubuntu 22.04, building a pinned Jetson Linux R32.7.5 flash tree, installing the Connect Tech TX2 BSP, and flashing a standard Jetson TX2 module on a Connect Tech Orbitty ASG003 carrier.

Scope

This repository is intentionally narrow:

Host: Windows 11 + WSL2 + Ubuntu 22.04
Module: NVIDIA Jetson TX2, standard P3310/P3310-1000 variant
Carrier: Connect Tech Orbitty ASG003
JetPack generation: JetPack 4.6.5
Jetson Linux / L4T: R32.7.5
Connect Tech BSP: CTI-L4T-TX2-32.7.5-V001
Target root filesystem: Ubuntu 18.04.6 LTS

Do not use the standard-TX2 flash profile for TX2i or TX2 4GB modules. Those variants have separate CTI profiles.

Validation status

Confirmed during the source session:

WSL2 Ubuntu 22.04 host preparation
usbipd-win installation and USB forwarding into WSL2
Generic USB passthrough validated end-to-end
NVIDIA R32.7.5 BSP and sample rootfs downloaded and verified
NVIDIA binaries applied successfully with QEMU
CTI TX2 R32.7.5 V001 BSP installed successfully
Orbitty ASG003 DTB and CTI profile present
Default-user image customization works
NVIDIA SDK Manager GUI launches under WSLg with the documented D-Bus workaround

The original module failed electrically before an end-to-end flash could be completed. The flash command and profile in this repository follow the installed CTI profile and CTI's documented manual-flash form, but the final USB flash should be validated with a known-good TX2 and then this notice updated.

Fast path

1. Prepare Windows and WSL2

Run PowerShell as Administrator:

Set-ExecutionPolicy -Scope Process Bypass
.\scripts\windows\setup-host.ps1

Open Ubuntu 22.04:

wsl -d Ubuntu-22.04

2. Install WSL dependencies

Inside WSL:

bash scripts/wsl/install-dependencies.sh

Keep the build tree in the WSL Linux filesystem, not under /mnt/c:

cp -a /mnt/c/path/to/this-repo ~/jetson-tx2-orbitty-wsl-flash
cd ~/jetson-tx2-orbitty-wsl-flash

3. Build the pinned flash tree

bash scripts/wsl/build-orbitty-flash-tree.sh

The completed tree is created at:

~/jetson/orbitty/build/Linux_for_Tegra

4. Optionally pre-create the target user

This skips the graphical OEM first-boot account setup:

bash scripts/wsl/create-default-user.sh

The script prompts for the username, hostname, and password without storing the password in this repository.

5. Put the Orbitty/TX2 into recovery mode

With the carrier powered and the USB OTG cable connected:

Hold Recovery.
Tap Reset.
Keep holding Recovery for about two seconds.
Release Recovery.

See docs/03-recovery-and-usb.md for the full USB forwarding sequence.

6. Attach the NVIDIA recovery device to WSL2

In Administrator PowerShell:

usbipd list

Find the line whose VID begins with NVIDIA's 0955, then run:

.\scripts\windows\attach-jetson.ps1 -BusId <BUSID>

Inside WSL:

lsusb | grep -i 0955
bash scripts/wsl/preflight.sh

7. Flash

Close SDK Manager before running the CTI/NVIDIA command-line flash.

bash scripts/wsl/flash-orbitty.sh

The deterministic manual profile used is:

sudo ./flash.sh cti/tx2/orbitty/base mmcblk0p1

The CTI interactive helper remains available as an alternative:

cd ~/jetson/orbitty/build/Linux_for_Tegra
sudo ./cti-flash.sh
