I need some help, I have spent 2 months trying to receive data with SCI.

I can send data with printf() redirecting to STDOUT, But I can't receive data using scanf() redirecting to STDIN

Hi David,

Do you mean to say that you're unable to receive any data sent from terminal application? Did you check the SCI-RXEMU or SCI-RXBUF register?

Gautam

I thought it only works with redirecting the stdout and stdin but I make it work with.

GPIO_SetupPinMux(85, GPIO_MUX_CPU1, 5);
GPIO_SetupPinOptions(85, GPIO_INPUT, GPIO_PUSHPULL);
GPIO_SetupPinMux(84, GPIO_MUX_CPU1, 5);
GPIO_SetupPinOptions(84, GPIO_OUTPUT, GPIO_ASYNC);
