How to enable CN8 UART RTS(on GPIO4)?

pna

Hello,

I am using Ubuntu 22.04 and is testing the UART on CN8 (mapped to /dev/ttyS6). However, I can't get the UART RTS to work. Is there anything I need to configure to get this working?

Thanks.

Hi Sir,

Can you provide BIOS version?

Hi Sir,

We have UART/COM on our board, can both not be used? Or only UART on HAT40 can't be used?
