Updating NVIDIA Jetson devices with Memfault OTA

NVIDIA offers one of the most comprehensive SDKs for developers of AI-heavy products. It includes a development kit that can emulate other devices in the lineup (Jetson AGX Orin DK), a simpler development kit for “entry-level” products (Jetson Orin Nano DK), a ton of exciting software libraries, AI models and even more examples of how to use them. It’s truly outstanding and out of the box shows up as a Ubuntu workstation which will feel very familiar.

However, it can be a bit daunting to figure out how to take this workstation experience and turn it into a headless unit that you can ship to customers far away and update remotely.

Diving into JTAG — Usage Scenarios (Part 5)

In previous articles, we have considered the primary uses of JTAG, including debugging and testing boards in production. For firmware developers, the first - debugging - is the most common. In this article, I want to look at two uses of JTAG Boundary Scan, which are also common tasks for a firmware developer: board bring-up and reverse engineering.

Practical Zephyr - West workspaces (Part 6)

In the previous articles, we used freestanding applications and relied on a global Zephyr installation. In this article, we’ll see how we can use West to resolve global dependencies by using workspace applications. We first explore West without even including Zephyr and then recreate the modified Blinky application from the previous article in a West workspace.

Embedded Open Source Summit 2024 Recap

Standout Exhibits at Embedded World 2024

In this post, I will share the technologies I saw at Embedded World 2024 that I was most impressed by. I was lucky to have plenty of time to walk from booth to booth, and had some fantastic conversations that I hope you will find interesting.

Practical Zephyr - Devicetree practice (Part 5)

In the previous articles, we covered Devicetree in great detail: We’ve seen how we can create our own nodes, we’ve seen the supported property types, we know what bindings are, and we’ve seen how to access the Devicetree using Zephyr’s devicetree.h API. In this fifth article of the Practical Zephyr series, we’ll look at how Devicetree is used in practice by dissecting the Blinky application.
