I wanted to use uart_c with hardware flow control. I see that GPIO header (J4) pin 15 and 16 is directly exposed as uart_c RX and TX respectively.
I dont see uart_c CTS and RTS are exposed directly on GPIO header. But looks like pin 35 and 37 are multifunction pins and can be programmed to use as uart_c CTS and RTS respectively.
If this understanding is correct, Can you please help me on how to program GPIO header pin 35 and 37 as uart_c CTS and RTS?
I have gone through suggested topic and feels that concerns are different. And hence created new topic.
I am able to activate uart_c and could able to use pin 15 (Rx) and pin 16 (Tx) for uart_c. But because of lack of flow control pins, observing data lose on higher baudrate.
I am looking for the ways to program pin 35 and 37 on GPIO Header for CTS and RTS. Can you please help in this regards?
In that case I shall not interfere,
but regarding your problem, I am sorry as my knowledge does not extend there yet, but I am sure that, contacting khadas staff might help you,
Thanks @numbqq.
I was trying with android image and building from source. So I have tried updating dts file to configure uart_c with CTS/RTS as you suggested.
I could enable flow control for uart_c and dont see data lose with higher baudrate.
