6.2 Configuring the FRDM-KL25Z microcode
Figure 13. FRDM-KL25Z setup and interface
By default, the FRDM-KL25Z delivered with this kit is preprogrammed with the current
and most up-to-date firmware available for the kit.
A way to check quickly that the microcode is programmed and the board is functioning
properly, is to plug the KL25Z into the computer, open FlexGUI, and verify that the
software version at the bottom is 6.4 or later (see
).
If a loss of functionality following a board reset, reprogramming, or a corrupted data
issue, the microcode may be rewritten per the following steps:
1. To clear the memory and place the board in boot loader mode, hold down the reset
button while plugging a USB cable into the
OpenSDA
USB port.
2. Verify that the board appears as a BOOTLOADER device and continue with step 3. If
the board appears as KL25Z, you may go to step 6.
3. Download the
Firmware Apps
.zip archive from the PEmicro OpenSDA webpage
(
http://www.pemicro.com/opensda/
). Validate your email address to access the files.
4. Find the most recent MDS-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA and
copy/drag-and-drop into the
BOOTLOADER
device.
5. Reboot the board by unplugging and replugging the connection to the
OpenSDA
port. Verify now that the device appears as a KL25Z device to continue.
6. Locate the most recent KL25Z firmware; which is distributed as part of the FlexGUI
package.
a. From the FlexGUI install directory or zip file, downloaded, find the firmware bin
file “flexgui-fw-KL25Z_usb_hid_gd31xx-Vx.x.x.bin”.
b. This .bin file is a product/family-specific configuration file for FRDM-KL25Z
containing the pin definitions, SPI/PWM generation code, and pin mapping
assignments necessary to interface with the translator board as part of
FRDMGD3162HBIEVM.
