Featured
From avocado init to a live four-model DeepStream 7.1 vision pipeline on a Jetson Orin Nano in about ten minutes of build plus a three-and-a-half-minute flash — the entire NVIDIA accelerated stack ships precompiled from the Avocado package feed.
Agentic Development
Avocado Desktop's built-in agent drives the Avocado MCP by chat. I described a Rust metrics exporter for a Raspberry Pi 4 in plain English, and the agent found a reference on its own, built a real Avocado extension, cross-compiled it to aarch64, and I flashed it to the board where the service was already running.
Portability
Moving an app across boards usually means standing up a new build per board. On Avocado OS the same Node.js dashboard runs on a QEMU VM, a Raspberry Pi 5, and a Jetson Orin Nano by changing one line: the target.
Security & Compliance
Physical access to the storage should not equal access to the data or the ability to run tampered code. This note wires LUKS2 encrypted /var, dm-verity rootfs integrity, IMA/EVM runtime appraisal, and TPM2-sealed keys into one boot chain on the i.MX93 FRDM.
Security & Compliance
A bad OTA can brick a whole fleet. Avocado OS pairs an immutable A/B rootfs with a two-boot rollback and a full on-device TUF trust chain, so a broken release reverts automatically and a tampered one never installs.
