kdb376: CTI-L4T Board Support Package Over the Air (OTA) Updates

Introduction

In Jetpack 4.3, NVIDIA updated their BSP process to include deb packages in anticipation for OTA updates in Jetpack 4.4. Over the Air Updates is a way to install or update NVIDIA packages using the apt command.

First Available BSP

Here are the first CTI Board Support Packages (BSPs) that have the OTA updates. Any BSP that we provide after these versions will be available via OTA updates.

Xavier NX - CTI-L4T-NX-32.4.3-V003 Nano - CTI-L4T-NANO-32.4.3-V002 AGX Xavier – CTI-L4T-AGX-32.4.3-V002 TX2 - CTI-L4T-TX2-32.4.3-V002

Available Packages

The following packages are custom to our BSP.

nvidia-l4t-kernel nvidia-l4t-kernel-dtbs nvidia-l4t-kernel-headers cti-l4t-utils

For a list of all of the packages, please visit NVIDIA L4T Documentation.

Changing Device Trees

With the addition of OTA updates, we can now also change the device tree without re-flashing using the relevant command.

For Xavier-NX

# sudo cti-nx-fdt.sh

For Nano

# sudo cti-nano-fdt.sh

For AGX Xavier

# sudo cti-agx-fdt.sh

For TX2

# sudo cti-tx2-dd.sh

After changing the device tree, the user must reboot in order for the device tree changes to take effect.

Installation

If you modify the nvidia-l4t-kernel package, the user must reboot in order for the changes to take effect.
