Please check that the default serial port used by TX2 is ttyTHS1~ttyTHS3, while ttyTHS4 is used for Bluetooth.Now I want to use ttyTHS5~ttyTHS7. Are these three serial ports used in the default configuration for other modules of the core board?I want to use all three serial ports, but I’m afraid they’ll get used up like ttyTHS4.Thank you very much!
you should also check pinmux spreadsheets or the pinmux configuration file for reference.
please also check Topic 145106 for reference.
BTW, ttyTHS serial ports were register during kernel initialize stage.
you might also refer to kernel messages, i.e.
$ dmesg | grep THS to check all mounted serial ports,
I see that the official PINmux is equipped with UART7, so how to use UART7 for the debugging of the system serial port?How do I configure it?
you may refer to Topic 54572 for the steps to enable UART-7.
