pi4 uart setup

Sun Jul 21, 2019 6:57 pm

Dear all , just got my new pi4 , i can see it has uart Tx on GPIO 12 and uart Rx on GPIO 13.
In order to use this as a serial port , gpio needs to be in ALT4 Mode , new /dev/ttyS5 device needs to be created and device file needs to be mapped to these pins.
Can any one help me do that.
Thank You
Sachin Singh
