系统可以通过SD卡引道之后,为了之后了调试方便 通过查看网卡的硬件设计 正常来说需要注意的有如下几点: 1) 网口 的接线方式: RMII 2) 网口的PHY地址两张网口,这里我们只需先初始化一张网卡,通过查看PHY的数据手册,可以发现其代码PHY地址是0. 3) 将对应的网卡驱动在include/configs/am335x_evm.h 添加对应的网卡驱动选项,以支持对应的PHY. Index: board.c==========================================…

由于上层应用的需求,需要运行arm docker,在kernel3.2上面还不支持,且编译器的glibc版本比较低的问题,故需要做系统升级 新的内核4.14.40驱动开发和以往有很大的不同,关键在于dts,本质来说就是把以往通过注册设备资源来加载驱动,查找总线的挂载的驱动,通过比较驱动名称,来加载驱动. 现在变成了通过dst来表述设备资源,对比驱动当中的id,来加载驱动. 第一阶段的目标: 由TI官网上面下载TI SDK 5.0,搭建成功之后,第一件事情就是希望系统能引导起来,能挂载文件系统,能…
