Debugging in MCUXpresso IDE

DHARSAN — Wed, 22 May 2024 11:45:15 GMT

I'm currently working UART communication of receiving while debugging in the controller with the board, it occurs Hardfault error so that I couldn't debug. Though when working in EVK board debugging works without any issue. And I have attached the screenshot below.

Could you please tell us which MCU/part are you using please?

Hello @DHARSAN

Do you mean the same example works well on EVK board, while there is issue with your own board?

How about debug a simple led or hello world demo on your custom board? Or create a new project based on your chip to test. Pay attention choose correct part number.

Hello @DHARSAN

"receiving same data in controller when transmitting different data from uart module"

->> If so, you need check your code.

But I'm working in the SDK example code which is modified for receiving only

Hello @DHARSAN

1> So recommend you first use SDK demo without any modification.

2> Check whether enable UART clock and pin clock you used.
