Overview
The NXP FRDM i.MX 93 development platform, enhanced with Avocado Linux and Avocado Connect, delivers a production-ready heterogeneous computing solution for edge AI applications. This integrated platform combines dual Cortex-A55 application processors, a Cortex-M33 real-time core, and an Ethos U-65 NPU to enable sophisticated edge processing with 0.5 TOPS of AI performance. The pre-integrated Linux and RTOS environment eliminates months of complex multi-core development, while EdgeLock security and atomic OTA updates ensure enterprise-grade deployment from prototype to production. Teams can leverage industrial connectivity options including CAN FD and Gigabit Ethernet to build secure, scalable edge AI systems that operate reliably in -40°C to +85°C environments with 10+ years of platform support.

Getting Started
The NXP FRDM i.MX 93 guide walks through the whole path for this board: prerequisites, the serial console, building, provisioning to an SD card, first boot, and running your own container so that it comes back after a power cycle.
avocado init --target imx93-frdm imx93-frdm
cd imx93-frdm
avocado install -f
avocado build
avocado provision -r dev --profile sd
Insert the SD card, connect the USB-C cable, and apply power. The root user is passwordless in the dev runtime.
