Project description
This PR goes beyond simply adding board names; it serves as a significant technical reference demonstrating how the Zephyr Hardware Abstraction Layer (HAL) defines and controls the RP2350 (Pico 2) and W6100. We have analyzed the key modified files to summarize the core technical details regarding hardware definitions and system configurations. 1. Device Tree (.dts) Analysis: Hardware Definition of W6100 The core of this update lies in the boards/wiznet/w6100_evb_pico2/w6100_evb_pico2.dtsi file. This defines how the Zephyr kernel recognizes and communicates with the W6100 chip. Ethernet Node…
