S32K14X Max UART Speed

Hello, 

For both S32 K144 and S32 K148, What is the max UART Interface speed achievable for reliable communication? 

If we go with the formula, we can always over sample UART, but error rates may be very high.

We want to get the more details on UART as we are going to use UART for reliable communication with Application processor.

 

Thanks..

Hello, 

the maximum baud rate supported by RTM SDK is 256 000. More details about LPUART module you can get in S32K reference manual  on page 1465+.

Hello, 

you can set the full speed in processor expert lpuart module settings:

I tested the full speed with putty serial terminal - and it is working. For your testing you can use example project lpuart_echo.
