Quickboot

Detailed Description

Applies to: Platforms with NVIDIA^® Tegra^® processors only.

Quickboot is the boot loader for all NVIDIA DRIVE^™ 5.0 products.

This customizable boot loader runs on AVP to initialize the CPU, after which it runs on CPU and starts the OS. In addition to booting the device, this boot loader can interact with NvFlash to obtain binary images on appropriate storage media. It then uses Fastboot to flash those images.

In addition to the above features, Quickboot:

• Provides a debugging mode
• Provides early display panel initialization
• Streamlines booting because it is optimized for embedded/automotive applications

For information on how to use the Quickboot API, client on the Modules tab.

For information on using Quickboot to flash the device, see the "Quick Start Guide" and "Flashing the Device" topics in NVIDIA DRIVE 5.0 Foundation PDK Development Guide.
