Hi All,
We can enable raspberry pi UART port for serial connection in /boot/config.txt by entering as below.
dtoverlay= UART3(GPIO 4,5) dtoverlay= UART4(GPIO 8,9) dtoverlay= UART5(GPIO 12,13)
Can anyone help how to enable UART port in Banana pi M4 where to configure .
I am using 2020-05-18-ubuntu-16.04-server-bpi-m4-aarch64-sd-emmc image.
