I am developing a system based on the FRDM-K64F. Watching the schematics (http://cache.nxp.com/files/microcontrollers/hardware_tools/schematics/FRDM-K64F_SCH.pdf) I noticed that the OpenSDA interface uses the MK20DX128VFM5 MCU as programming and debugging drive. If I buy the MK20DX128VFM5 MCU, it has the bootloader included by Factory default?
Hello Jhonatan Mejía:
Actually no, the MK20DX128VFM5 does not have the OpenSDA firmware loaded from factory. In the next document there is a description of OpenSDA and there is also a binary file attached to program the bootloader to the K20:
I hope this helps.
Regards!
