T1042/T2080 vxWorks7开发笔记（二）

本章节主要讲解如果根据组件或根据设备树查找对应的驱动

网口驱动设备树

&fman0 {

ethernet@f0000 {

compatible = "fsl,fman-memac";

reg = <0xf0000 0x1000>;

};

mdio@f1000 {

#address-cells = <1>;

#size-cells = <0>;

compatible = "fsl,fman-memac-tbi";

reg = <0xf1000 0x1000>;

};
MAC名称为fman-memac，在内核组件查询memac
可以看到这里的phy ，mdio，mac驱动都找到了，点击获取更加详详细的信息

用search 查询具体的驱动文件

网口驱动目录所在路径

查看串口对应驱动

serial0: serial@11c500 {

cell-index = <0>;

device_type = "serial";

compatible = "fsl,ns16550", "ns16550";

reg = <0x11c500 0x100>;

clocks = <&platform 1>;

clock-names = "platform-div2";

interrupts = <36 2 0 0>;

interrupt-parent = <&mpic>;

};

serial1: serial@11c600 {

cell-index = <1>;

device_type = "serial";

compatible = "fsl,ns16550", "ns16550";

reg = <0x11c600 0x100>;

clocks = <&platform 1>;

clock-names = "platform-div2";

interrupts = <36 2 0 0>;

interrupt-parent = <&mpic>;

};

Component DRV_SIO_FDT_NS16550 {

shell中不同于以往版本的几个命令

vxbDevShowPaths

Note: the "original" path uses the name of the device before a driver is bound. This

is the path that must be used when blacklisting devices for the hypervisor
