MKV30F64VLH10 working in debug mode but not working after power cycle.

[vaibhavsomani]

Hi

I am trying to flash Freescale MKV30F64VLH10 on my board. I am flashing via PE micro Multilink Universal.
When I debug or flash via KDS3.0 and while JTAG connector is connected, my code works as defined. I am getting correct output on gpio.
But when I power off and power on the supply, I am not getting the output on gpio. And  I am getting a pulse on rest pin (looking like mcu is not getting programmed !!).

Please suggest some solution for this problem.

Here is the console output....

Hi Vaibhav,

I was able to run your project on my FRDM-K22F (I do not have FRDM-KV31) from debugger and from Power-On Reset.

You might add strong pull-up to PTC4 (NMI) signal.  It is enabled by default.

Or you can go into thte startup_MKV30F12810.S and modify the Flash Configuration field to disable NMI capability:

Default Flash Configuration:

    .section .FlashConfig, "a"

    .long 0xFFFFFFFF

    .long 0xFFFFFFFF

    .long 0xFFFFFFFF

    .long 0xFFFFFFFE

Modified Flash Configuration to disable NMI (FOPT[NMI]=0):

    .section .FlashConfig, "a"

    .long 0xFFFFFFFF

    .long 0xFFFFFFFF

    .long 0xFFFFFFFF

    .long 0xFFFFFBFE

Regards,

David

Thanks DavidS once again !!

My problem is solved after changing code as suggested by you :smileyhappy:
and I found on my board NMI pin was pulled down. So i will make it pull-up.
You picked the problem very accurately :smileyhappy:

Thanks;

Thanks DavidSfor quick reply.
I have TWR-KV31F120M. My code is also working fine on TWR-KV31.
But when I am flashing same code on my board, on power on reset or reset through pin. It is not working.
In debug mode when jtag connector is connected, I tried to do reset via reset pin. My cursor/pointer is showing DefaultISR due to WDOG_EWM_IRQHandler() ??

And this is defined as dead loop in startup_MKV30F12810.S file. So whenever a reset or power on reset happens it is going to  DefaultISR and stuck in dead loop. Here is the screenshot ..

Please suggest how to overcome on this ?

Hello Vaibhav Somani,

please, how do you have connected RESET pin?

Best Regards,

Iva

Reset pin has a 100nF capacitor and pull up with 6.8k

resistor.
