I am working on Rock Pi S V13 hardware. On that build I am using Yocto image as OS. I want to enable uart03, but I can’t find any related details regarding uart03.
I checked pin diagram for rock pi S, on that they’ve mentioned pin 39 and pin 40 as UART3.
Then I checked device overlays, they didn’t mention anything about uart3. I can see only uart0, uart1, uart2.
I am struck in this. Please help me with this as soon as possible.
