Instruction trace cause reset

biafra — Wed, 27 Mar 2019 16:32:30 GMT

hi everyone,

I'm working on a custom board based on MK66FN2M0 device using MCUXpresso 10.3.1.

I'm trying to discover an error and I have to use the instruction trace feature.

If I leave disabled the instruction trace, the program runs fine (except the error I'm trying to find).

But if I pause the execution, enable the instruction trace and resume, the processor resets after few instructions. It doesn't matter where or when I enable it, even at the program start.

What can be the reason of this bahviour?

Many thanks

Biafra

Hello,

The MTB may be overwriting code or data on the target. Check that the MTB’s memory configuration is compatible with the target’s memory configuration.

Regards,

Aldo.

Hi nxf46838‌,

As far as I know, MK66 have ETB, not MTB.

Many thanks

Hi nxf46838‌,

Where can I check the MTB's memory configuration?

Many thanks

Hi nxf46838‌,

The problem is present only when I debug my project.

Many thanks,

Hi,

If possible try to run your code in one of our boards (FRDM-K66), this in regard that maybe something of your custom board is causing the reset.

Aldo.
