在Linux系统中,查看串行端口(Serial Ports)通常涉及以下几个基础概念和相关操作: 基础概念 串行端口:一种用于数据传输的接口,通常用于连接外部设备如调制解调器、打印机等。 设备文件:在Linux中,硬件设备通常以文件的形式存在于/dev目录下,串行端口设备文件通常是/dev/ttyS*(对于传统的RS-232端口)或/dev/ttyUSB*(...

serial_out(port, sw_uport->ier, SW_UART_IER); } } serial_out函数对应的就是最底层的寄存器操作了,这里#define SW_UART_IER (0x04),SW_UART_IER_THRI它对应的是使能中断,具体要参考全志的A20 CPU手册: static inline void serial_out(struct uart_port *port, unsigned char value, int offs) { _...

That is why it seems easier to just use root credentials to use any device, serial ports included. Needless to say that writing to the wrong device can be quite dangerous. For instance, writing to a device like /dev/sda (first Sata device) might lead directly to data corruption. That’...
