Using OpenSDA in a Custom Board

[gustavocosta]

Hi there,

I'm moving to my custom board now and my initial idea was to use the OpenSDA circuitry in it to provide an easy way of flashing and debug my K64 MCU. 

The MCU I choose to work with was MK64FN1M0VLQ12 so it is a different package compared to the ones present in FRDM-K64 and TWR-K64.

My question is: Will I be able to use this circuit for flashing, debugging and communicate (USB to Serial) considering those differences?

Also, should I use the OpenSDA circuitry based on FRDM or TWR?

Thank you very much.

Best regards,

Hi,

You can use USB DFU if you want that the user can update the firmware trought a pc.  USB DFU boot loader for MCUs 

With KSDK and uTasker is possible.  µTasker USB Device Configuration 

You can use SWD o JTAG to debug.

OpenSDA is not recommended to production.
