Hello,
I'm using the FRDM-KL25Z board with flexGUI. It's the warning: Currnet KL25Z firmware version is 0.8.7. Please upgrade to version 0.8.8 or later to ensure proper software operation. Where can I get the latest firmware? Tks
In order to update the firmware in the FRDM-KL25Z you need to go to the following link:
OpenSDA Serial and Debug Adapter | NXP Semiconductors
Go to the Download - OpenSDA Bootloader and Application and select FRDM-KL25Z
With this the page will give you different option to update to the latest firmware.
