The KIT33882EKEVB kit may be used with the FSD (see
Figure 5
), which provides a USB-to-SPI interface. This small board makes use
of the USB, SPI and parallel ports built into Freescale's KL25Z microcontroller. The main function provided by this dongle is to allow
Freescale evaluation kits that have a parallel port to communicate via a USB port to a PC. It can also be used as a regular microcontroller
board if not configured as a SPI dongle.

Using the FRDM-KL25Z as a FSD
First, the MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must be loaded to the FRDM-KL25Z board. This is accomplished by
plugging the mini-USB cable into the SDA USB port on the FRDM-KL25Z while holding down the reset button. The green LED should be
flashing. The MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must then be drag and dropped onto the BOOTLOADER drive in
Windows Explorer. The FRDM-KL25Z should be unplugged after the file has been transferred. The mini-USB cable must then be plugged
back into the SDA USB port on the FRDM-KL25Z. The FSD srec file can then be drag and dropped onto the FRDM-KL25Z drive in
Windows Explorer. To use the FRDM-KL25Z as a FSD, the mini-USB cable must be plugged into the KL25Z USB port.

Using the FRDM-KL25Z as a Microcontroller Board
4.2.1
Using the FRDM-KL25Z Sample Code Drag/Drop File
First, the MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must be loaded to the FRDM-KL25Z board. This is accomplished by
plugging the mini-USB cable into the SDA USB port on the FRDM-KL25Z while holding down the reset button. The green LED should be
flashing. The MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must then be drag and dropped onto the BOOTLOADER drive in
Windows Explorer. The FRDM-KL25Z should be unplugged after the file has been transferred. The mini-USB cable must then be plugged
back into the SDA USB port on the FRDM-KL25Z. The sample code srec file found in the SPIGen website can then be drag and dropped
onto the FRDM-KL25Z drive in Windows Explorer. To use the FRDM-KL25Z with this sample code, the mini-USB cable must be plugged
into the KL25Z USB port.
4.2.2
Using the FRDM-KL25Z with Custom CodeWarrior Code
First, the MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must be loaded to the FRDM-KL25Z board. This is accomplished by
plugging the mini-USB cable into the SDA USB port on the FRDM-KL25Z while holding down the reset button. The green LED should be
flashing. The MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA file must then be drag and dropped onto the BOOTLOADER drive in
Windows Explorer. The FRDM-KL25Z should be unplugged after the file has been transferred. To use the FRDM-KL25Z as a
programmable microcontroller with CodeWarrior, the mini-USB cable must be plugged into the SDA USB port. Sample code for this kit is
available at the kit’s website.
