MKL25Z - Fresh device programming via USB port

Hello everyone,

 

Is it possible to flash a bootloader into a fresh new MKL25Z128VLK4 mcu via USB port (without using SWD/JTAG port)? Or I do need to breakout JTAG pins to my custom KL25 board, and buy an external programmer?

 

My goal is to to set up by custom board as Mass Storage Device so that new binaries can be copied on it, just like the FRDM behavior.

 

Thanks in advance
