Podcast Guest: Daniel Mangum on Crossplane, building a PaaS, and Multi-Cluster Kubernetes (LOTE)

In our last post, we explored the Nordic VPR RISC-V processor through the lens of the peripheral processor (PPR) on the nRF54H20. While we demonstrated how the application processor can configure and start a VPR processor, we stopped short of demonstrating any further communication between them. Most meaningful use-cases of the PPR and the FLPR,...

VPR (pronounced “Viper”) is Nordic Semiconductor’s first RISC-V processor, landing in the new nRF54H and nRF54L lines of SoCs after their initial announcements in April and October of 2023 respectively. Readers of this blog are familiar with my long-running obsession interest in RISC-V (see my RISC-V Tips and RISC-V Bytes series). However,...

Nordic Semiconductor recently made their new IoT prototyping platform, the Thingy:91 X, generally available. The Thingy:91 X is an upgrade to their existing prototyping platform, the Thingy:91, replacing the nRF9160 System-in-Package (SiP) with an nRF9151 SiP, the nRF52840 System-on-Chip (SoC) with an nRF5340 SoC, and adding the nRF7002...

Well, not this one. But this one is! How? Let’s take a closer look at Bluesky and the AT Protocol that underpins it. Note: I communicated with the Bluesky team prior to the publishing of this post. While the functionality described is not the intended use of the application, it is known behavior and does not constitue a vulnerability disclosure...

The ESP32-S3 is a popular microcontroller (MCU) for a variety of reasons, such as its support for external pseudostatic RAM (PSRAM). One of its lesser known features is its Universal Serial Bus (USB) On-The-Go (OTG) controller. The previously released ESP32-S2, as well as the new ESP32-P4, also have USB OTG support, with the latter having two...
