I am developing a networked solution based in FRDM-K64 board.
This board have a lot of nice features that I will not use and in the other hand I need to free some GPIOs to make use of them for this project .
So the idea is to design a tailored FRDM-K64 board without most of its periferal devices, the less components possible but keeping its ethernet capabilities.
One of the things that I need to get rid of, is the OpenSDA interface, If so... Is there anyway to make use of the the axf file generated by MCUXpresso? Haw can I program the MK64FN mcu without the OpenSDA interface?
Hello Luis,
You will need an interface to program the K64-F. If you want to save pins I would recommend to use Serial Wire Debug (SWD) interface. Different from JTAG interface, SWD only takes two pins:
Hope it helps!

Thanks Victor. This I have clear. Do you know if it is possible to setup MCU Expresso to program the board using the SWD interface?
Regards,
Luis
Hello Luis,
The fully featured debugger supports both SWD and JTAG debugging, and features direct download to on-chip and external flash memory.
Link to MCUXpresso IDE User Guide.
Hope it helps!
Victor.
