MSP432P401R: UART errorfxn is getting called occassionally.

Hi,

Can you share your code? How are you setting up the driver?

Thanks,

Hello,

UART config is as below-

uartA2Params.writeDataMode = UART_DATA_BINARY;
uartA2Params.readDataMode = UART_DATA_TEXT;
uartA2Params.readReturnMode = UART_RETURN_NEWLINE;
uartA2Params.readEcho = UART_ECHO_OFF;
uartA2Params.baudRate = 57600;
uartA2Params.readTimeout = 200;
uartA2Params.writeTimeout = 400;

Error Function is getting called occasionally. From where I can get the error info with the error code that I'm getting from the error callback function. I'm talking about the below error callback in UARTMSP432.h

Regards,

KA

But I'm unable to decode the errors using UCAxSTATW for errors 8 & 36. Could you guide me?

Hi,

I am not sure what you mean by decoding the errors. Below is a thread with an example code that shows how to setup the device to flag an error from STATW register. Is that what you mean?
