Getting Started

What's Pre-Installed

When you order an ARK Just A Jetson bundle:

• Jetson: Latest ARK kernel

• Credentials: Username jetson, password jetson

Important: Custom Kernel Required

The ARK Just A Jetson requires a custom device tree to enable all hardware features. If you reflash your Jetson, you must use the ARK kernel with the correct device tree.
