Tool/software: TI-RTOS
I want to use PRU UART for the general UART communication.so I download the example program(C:\ti\pru\examples\am437x\PRU_Hardware_UART) from pru-addon-v4.0-Windows-Install.exe to test the PRU UART port.But when I unable loopback , I can get the data from the hard line(pro_uart0_rxd/txd).
should I set pin mux before running this example? can it be set in the pru?
before, I use the C:\ti\pru\examples\am437x\PRU_gpioToggle to test the PRU GPIO,I can operate GPIO directly without any others.
I have read the answers to other questions and found that the pinmultiplex setting must be done in ARM. How can I do so?
