In Linux, how to use the USB-to-serial-to-Linux Enterprise Application-to-Linux server application information is as follows. The serial port of the computer cannot be used. How can I connect to the serial port of the target board?
In windows, you can use USB-to-serial-to-linux!
Test environment: redhat linux fedora core 4
Summary:
1. Check whether the device/dev/ttyUSB0 exists. If not, create one:
Mknod/dev/ttyUSB0 c 188 0
The following reasoning is not tested:
If there are multiple USB ports, and so on, create/dev/ttyUSB [1-n]. Note that the device numbers must be accumulated, such as mknod/dev/ttyUSB [1-n] c 188 [1-n].
2. Start minicom, set the serial device to/dev/ttyUSB0, set the baud rate/Data bit/stop bit, and save as the default df1 Configuration
3. Restart minicom and reset the target board to see if any printed information is available?
If not, please confirm: a) there is no problem with the USB/serial cable, B) Make sure that the USB port you are using is the first one (try one by one, generally the computer will not mark it out)
