Controller is not working without JTAG

[prasannanaik]

Hi, in MKE04Z64VLH4, controller is not working without JTAG. As one switch the supply OFF and then ON controller stop working. I have check the RESET pin status it is pull up to VDD. Controller is running on External oscillator with Core clock is 40 MHz, Bus clock is 20 MHz and OSCER clock is 8 MHz. In attachment I have attached sample code and the RC value which is connected on RESET pin.
KIndly let me know the reason why is it not working ? Is it any issue in firmware or hardware modification required.

Hi Prasanna Naik,

    Thank you for your interest in NXP kinetis product, I would like to provide service for you.

    Do you mean, when you use the JTAG interface, eg SWD, you can debug the code, and when disconnect the debugger, just POR, the APP can't work?

    What the IDE you are using? CW, KDS or MCUXPresso?

    If you are using the CW, please check this configuration:

You need to chose ewl instead of ewl_hosted.

Please try it on your side, thank you.

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi Kerry,

   Thanks for your input. I am using MCUXpresso IDE for development. I am able to use the controller in debug mode(i.e with SWD) but it doesn't work without SWD(Normal operation mode). Also please check whether the RC value connected on the RESET pin is sufficient or not.

Thanks and best regards,

Prasanna

Hi Prasanna Naik,

    RESET pin external circuit is correct.

    What's the board you are using? You own board or the NXP official board?

    NMI pin need external 4.7K to 10K pull up resistor, do you have it? If you don't have it, you can add one 10K external pull up resistor on PTB4 pin.

You can check it.

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi kerryzhou‌,

   Thanks for your help. 

  It was a problem due to NMI pin connections. It worked after your suggestion.

Thanks and best regards,

Prasanna
