5 Installing and configuring software and tools
The programming/evaluation boards are always delivered with the GUI firmware already flashed. If MCU
firmware is already flashed, ignore this section. If it is specified that firmware must be updated or it is
malfunctioning, follow these instructions.
5.1 Flashing or updating the FRDM-KL25Z GUI firmware
If bootloader is already loaded in the FRDM-KL25Z board, steps 1-3 are not required. Start from step 4.
1. Disable the Storage Service and Windows Search: Run Services, double click, and stop them as shown in
Figure
13.
Figure 13. Services configuration
2. Press the RST push button and connect the USB cable to the SDA port on the FRDM-KL25Z board.
• A new "bootloader" device appears on the left pane of the file explorer
3. Drag and drop the file "MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA" to the bootloader drive
Ensure that there is enough time for the firmware to be saved in the bootloader
4. Disconnect the USB cable, then reconnect it to the SDA port WITHOUT pressing the RST push button
• This time, FRDM_KL25Z device appears on the left pane of the file explorer as in
Figure 14. FRDM-KL25Z in left pane
5. Locate the file "nxp-gui-fw-frdmkl25z-usb_hid-device_<version>.bin" from the package. Drag and drop this
file into the FRDM_KL25Z device.
Ensure that there is enough time for the firmware to be saved.
6. Freedom board firmware is successfully loaded. Disconnect the USB-cable and reconnect it to the KL25Z
USB port.
