Tool/software:
Hello，
The hardware we have developed ourselves now uses mcu_uart0 and mcu_uart1 in Linux. We have defined it in the device tree and the corresponding pins have been compared. After testing, it was found that neither of these ports is working properly, but I use real-time checking of mcu_uart1 operation , can send and receive data. I printed out the information related to my device tree file and serial port operation. I hope you can help analyze it.Another phenomenon is that I use the command to view the serial port status. In any case, the sending count of mcu_uart1 is 381, and this number is displayed every time I power on.The test process is to enter the echo command in the debugger serial port, and send the data to the serial port of the PC through mcu_uart1. The serial port connection line has been confirmed to be no problem.
