s32k144 lpspi

When I am using the LPSPI of S32K144 and change the SPI baud rate to 800KHZ or any other value instead of 1MHZ, I notice that the S32K144 keeps resetting continuously. Similarly, changing the SPI clock also leads to continuous resets. I can only maintain the baud rate at 1MHZ and the clock frequency at 8MHz for the S32K144 to work properly. Could you please tell me what could be the reasons for this kind of behavior?

Hi @fengba_360,

What is the source of the reset?

Can you read RCM_SRS after the reset?

If you can't attach the debugger, use another communication peripheral to send it out.

 

Do you have HardFault_Handler() implemented in the project?

 

Or can you share the project so that I can test it?

 

Thank you,

BR, Daniel
