🎤 Over-the-air (OTA) software updates with NVIDIA Jetson
06 Feb 2022 show details

With over half a million developers worldwide, NVIDIA® JetsonTM is one of the most popular embedded computing platforms that brings AI performance to the Edge in a power-efficient and compact form factor

In this talk, we will cover in detail a unique way of integrating a robust and secure over-the-air software (OTA) updates with the NVIDIA JetPack 4.6 production release that works for all Jetson System-on-Modules (SoMs) with support for the official L4T (Ubuntu-based) operating system, running JetPack 4.6 or later. As it is built on top of the latest JetPack SDK release, there is no need to have separate integrations when building and deploying applications on different Jetson SoMs. This has the benefit of enormously cutting down the bringup time of an OTA solution to do all types of OTA updates. It has low maintenance costs since it does not involve modifying the boot process and rather relying on officially supported tools by NVIDIA which should not “break” with new L4T releases or board changes. We will cover the details of the integration with the high-level user flow as outline below, which “clones” the running image of a golden device and deploys it in a robust manner to the entire fleet of devices:

-Download L4T image from NVIDIA -Use NVIDIA tools to flash A/B setup with L4T image -Install Mender as deb package, plus integration layer -Run Mender snapshot to create Artifact -Deploy Artifact snapshot to fleet
