Ezurio (formerly Laird Connectivity) BL5340 DVK — Zephyr Project Documentation
The BL5340 Development Kit provides support for the Ezurio BL5340 module which is powered by a dual-core Nordic Semiconductor nRF5340 ARM Cortex-M33F CPU. The nRF5340 inside the BL5340 module is a dual-core SoC based on the Arm® Cortex®-M33 architecture, with:
-
a full-featured Arm Cortex-M33F core with DSP instructions, FPU, and Armv8-M Security Extension, running at up to 128 MHz, referred to as the application core
-
a secondary Arm Cortex-M33 core, with a reduced feature set, running at a fixed 64 MHz, referred to as the network core.
The bl5340_dvk_cpuapp build target provides support for the application core on the BL5340 module. The bl5340_dvk_cpunet build target provides support for the network core on the BL5340 module. If ARM TrustZone is used then the bl5340_dvk_cpuapp build target provides support for the non-secure partition of the application core on the BL5340 module.
