About the console UART of EDGE-V

Hi, I have the problem of console UART with ubuntu 18.04 on edge-v. I need to use the debug UART /dev/ttys0 (pin 18, 19) as a normal UART to transmit data. May I have your help with how to change the debug UART as a normal one? I’ve tried several methods from other Linux-Arm communities but not work. Any suggestions will be appreciated. Thanks
