嵌入式Linux系统关闭串口调试信息的输出

在嵌入式Linux系统中，有时需要关闭调试串口，不让调试口输出信息，这也可以保证系统程序的安全。关闭调试串口输出的方法也很简单，可以在uboot阶段通过修改参数来实现，参数设置如下： setenv bootargs 'mem=756M console=null,115200 initr...

基于瑞芯微RV1109 Linux串口驱动调试心得(给正点原子DS100示波器点赞！)

在调试的时候发现板厂供应商调整了RK原厂的原理图设计，然后他们把串口5原来的M0的连接换成了另一路IO M1，也就是说他们并没有按照原厂的原理图去设计，所以UART5根本动不起来，由于好久没搞驱动了，对驱动也不熟，所以只能硬着头皮追代码、上示波器、上逻辑分析仪调试等等，走了很多弯路，最后终于把问题给找出来了，在此记录一下调试过程。1、关于uart5节点pinctrl配置的描述uart5 { ...
