Hi Radoslav Iliev
First of all, are you using the frdm-KL02z or the frdm-KE02z? Anyway, please go to the web page:
OpenSDA Serial and Debug Adapter|NXP
and download the latest firmware application and "drag and drop" into the Bootloader msd that appears in your system. For more information please check:
OpenSDA on the Freedom KL25Z Board | MCU on Eclipse
Have a great day,
TIC
