In this tutorial, we're going to connect to an external Ethernet controller (a network card, if you like) using the RPi4's Serial Peripheral Interface (SPI). Things you'll need: * An [ENC28J60 Ethernet module](https://www.amazon.co.uk/dp/B00DB76ZSK) - it cost me less than £...

flash上启动系统,这需要对Uboot和系统镜像做些适配。 本文介绍SPI Flash镜像的制作过程。 一、Flash分区规划# 这里 使用 MX25L25645G,32M SPI flash作为启动介质,规划分区如下: 二、Uboot编译配置# 由于目前Uboot环境变量固定存放在1MB位置之内,所有留给uboot的空间固定到flash前1MB的位置不变。
It is designed to serve as an Ethernet network interface for any controller equipped with SPI. The ENC28J60 meets all of the IEEE 802.3 specifications. It incorporates a number of packet filtering schemes to limit incoming packets. It also provides an internal DMA module for fast data ...
