20241114给荣品PRO-RK3566开发板刷Rockchip原厂的Android13下适配RJ45以太网卡
2024/11/14 15:44
缘起：使用EVB2的方案，RJ45加进去怎么也不通。
实在没有办法，只能将荣品的SDK：rk-android13-20240713.tgz
解压缩，编译之后。
从中析取最小的DTS，然后拿掉不用的部分，比如LCD/TP等。
很艰难地得知/根据经验/很容易知道RJ45以太网卡的DTS代码块在这里：rp-gmac1-m0-pro-rk3566.dtsi
以太网卡终于可以打开了，但是还是有小BUG：
1、千兆网啊变成百兆网卡了。难道还有4根线中有GPIO引脚被复用了？
2、iperf3不能连接，原因待查。

你加进去EVB2之后，还是不会找到以太网卡的！^_
于是用荣品的DTS和原厂的EVB2的DTS进行比对。
很艰难地得知/根据经验/很容易知道是显示部分影响了RJ45以太网卡。
我就简单干脆地关闭DSI0/DSI1和TP。
以太网卡终于可以打开了，但是还是有小BUG：
1、千兆网啊变成百兆网卡了。难道还有4根线中有GPIO引脚被复用了？
2、iperf3不能连接，原因待查。
