USBDM vs PEMicro Initializations

andrewmeyerbti — Wed, 10 Sep 2025 13:00:16 GMT

I have some software for a FRDM-KE06Z demonstration board which communicates over the CANBus. It works when connected using USBDM, but it does not work when not connected to a debugger. It also does not work when connected using PEMicro open debugger, though the software is running and the basic functionality is there--just no CanBus communication as far as I can see. I have checked Canbus frequencies for individual components with a scope and all seems good.

Are there any known differences in initialization between the USBDM debugger and the PEMico debugger which might help me determine what is lacking?

Is there any way to dump all the registers from the running software to a file, so I can compare differences between the two different debugging instances?

Thank You

Hi @andrewmeyerbti,

Could you help me with the following questions?

Which IDE are you using?
Are you using an SDK?
Have you made any changes to the project configuration?

Best Regards,

Pablo

Hi Pablo,

I'm using Kinetis Design Studio V3.2.0 which I believe uses a kinetics SDK which it installs itself, so not quite sure what version. I didn't make any intentional changes to the project configurations--that being said sometimes mysterious things happen even on my isolated network.
