Windows

Here we use putty as an example to show us how to set the serial debug tools.

Select the Serial, Fill the Serial line with the right serial port,and the Speed with 115200

Linux

Here we still use putty as an example. when start putty firstly you will see this interface:

Select the Serial, Fill the Serial line with the right serial port,and the Speed with 115200

How to get the serial port .First cat /proc/tty/drivers, to make sure is there driver support(radxa board is connected with pc via USB so the device name should be usbserial)

Here we find the line

usbserial            /dev/ttyUSB   188 0-253 serial  

which tell us the driver is ok, then cd /dev/ to confirm whether is there device named ttyUSB* . you can unplug and then plug the usb to get the right device.

Finish setting, Click Open the putty will work!
