There is a question about the TMS570LC43x LaunchPad Development Kit.

When I use the SCI3 as a UART , I find that it can only receive data and can not send data. Why?

Can anyone help me?

Hi,

Can you pls check if you have the pinmux configured properly for SCI3 ?

I'm sure I have configured it properly. I find that the register has changed correctly, but it seems that the data can not be sended. I doubt if there is some prombles of the hardware about the SCI3 Tx pin.
Can you pls give me a hand?
Best Regards,
Caven.
