Enabling UART on VIM4 using Ubuntu Desktop image doesn't work

Ubuntu Desktop

Khadas official

Please describe your issue below:

When trying to enable the available UART with this information UART | Khadas Documentation, no /dev/ttyS4 device file is being creating

After trying a couple of other possible obvious device files, I gave up.

Please can you provide me accurate information about what should work?



Edit file /boot/dtb/amlogic/kvim4.dtb.overlay.env add uart_e to node fdt_overlays=, save and reboot.

You will find node /dev/ttyS4.

Thanks a lot Nick for the quick response. Works like a charm now.
