S32K566 LPUART Communication Issue

[Manikandan_Aruchamy]

Hi,

I am using the Uart_Example_S32K566_M7 module on the S32K566 microcontroller with an LPUART module clock of 50 MHz. I configured the baud rate to 115200 and am sending 0xAA data to the PC using a UART-to-USB converter. However, the received data is incorrect (0x00 0x80 0x80). When I configure the baud rate to 115200/8 = 14400, the data is received correctly. I also tried different baud rates such as 9600 and 19200.

I am using S32DS 3.6.6 and SDK 0.8.0.

Uart_Example_S32K566_M7 source code also attached here please find. 

I have attached the configuration and received data screenshots for reference.

Receiver terminal window baud rate is 115200:

Receiver terminal window baud rate is 14400:
