Project description

This article explains how to implement Ethernet communication using the W5500 SPI-to-Ethernet module on the Forlinx OK-MX9352-C development board. The W5500 is an SPI-based Ethernet controller that supports 100Mbps Ethernet and up to 80Mbps SPI data rates. The content includes: Hardware Connection: Pin mapping between W5500 and OK-MX9352-C (LPSPI3 and GPIO). Kernel Configuration: Enabling WIZnet SPI Ethernet drivers in the kernel menuconfig. Device Tree Settings: Adding W5500 configuration under the SPI3 node, including GPIO for chip-select, interrupt, and reset. Driver Build and Deployment…
