Quick Start Guide for FRDM-KL46Z Rev 1

The Freescale Freedom development platform is a set of
software and hardware tools for evaluation and development.
It is ideal for rapid prototyping of microcontroller-based
applications. The Freescale Freedom KL46Z hardware,
FRDM-KL46Z, is a simple, yet sophisticated design featuring a
Kinetis L Series microcontroller, the industry’s first
microcontroller built on the ARM® Cortex™-M0+ core.

Features:

• MKL46Z256VLL4MCU – 48MHz, 256KB Flash, 32KB
SRAM, segment LCD, USB OTG (FS) , 100 LQFP

• Capacitive touch slider, MMA8451Q accelerometer,
MAG3110 magnetometer.

• Flexible power supply options – USB, coin cell battery,

external source

• Easy access to MCU I/O

• Battery-ready, power-measurement access points

• Form factor compatible with Arduino ™ R3 pin layout

• OpenSDA debug interface

• Mass storage device flash programming interface (default) –

no tool installation required to evaluate demo apps

• P&E Debug interface provides run-control debugging and

compatibility with IDE tools

• CMSIS-DAP interface: new ARM standard for embedded
debug interface Refer to the FRDM-KL46Z User’s Manual and

OpenSDA User’s Guide for more information.

Installing Drivers and Running the Out of Box Demo

FRDM-KL46Z comes with the mass-storage device
(MSD) Flash Programmer OpenSDA Application
preinstalled. It will appear as a removable storage
drive with a volume label of FRDM-KL46Z

The MSD Flash Programmer also includes a USB
virtual serial port which requires an .INF file for proper
installation in Windows. The necessary .INF file is
available in the P&E OpenSDA USB Drivers (Step 0)
and also on the FRDM-KL46Z removable drive.

If the USB CDC Serial Port fails to automatically install
in Windows, follow the instructions in Step 2.
Otherwise, skip to Step 3.

Optional: Download and Install the P&E OpenSDA
USB Drivers found at www.pemicro.com/opensda.

Plug in a USB cable (not included) from a USB host to

the OpenSDA mini-B USB connector. The FRDM­KL46Z will be powered by this USB connection.

a. Open Device Manager
b. Locate and right-click on “OpenSDA –

CDC Serial Port”

c. Select “Update Driver Software”

d. ”Browse” and select the FRDM-KL46Z

drive
e. Click “Next” to complete the

installation

The pre-installed demo running on the

KL46 MCU shows different features of

the board including segment LCD, an
implementation of e-compass function
based on board accelerometer and
magnetometer as indicated on following
page.

Quick Start Guide for FRDM-KL46Z Rev 1

The MSD Flash Programmer is a composite USB application that provides a virtual serial port and an easy and
convenient way to program applications into the KL46Z MCU. It emulates a FAT16 file system, appearing as a
removable drive in the host file system with a volume label of FRDM-KL46Z. Raw binary and Motorola S-record files
that are copied to the drive are programmed directly into the flash of the KL46 and executed automatically. The
virtual serial port can be opened with standard serial terminal applications.

Using the MSD Flash Programmer

Using the Virtual Serial Port

Open the serial terminal emulation program of
your choice. Examples for Windows include Tera

Term, PuTTY, and HyperTerminal.

Program one of the “serial test” applications from
the Precompiled Examples folder using the MSD
Flash Programmer.

Configure the terminal program. Most embedded

examples use Baudrate115200, 8 data bits, no
parity bits, and one stop bit (8-N-1).

Press and release the Reset button (SW1) at
anytime to restart the example application.
Resetting the embedded application will not affect
the connection of the virtual serial port to the
terminal program.

NOTE: Refer to the OpenSDA User’s Guide for a

description of a known Windows issue when
disconnecting a virtual serial port while the COM
port is in use.

The new application should now be running on the
FRDM-KL46Z drive.

Program FRDMKL46_Demo_freedom.srec
example to replace the out-of-box demo on your
FRDM-KL46Z drive.

Determine the symbolic name assigned to the
FRDM-KL46Z virtual serial port. In Windows

open Device Manager and look for the COM port

named “PEMicro/Freescale – CDC Serial Port”.

OpenSDA is an open-standard serial and debug adapter. It bridges serial and debug communications between a
USB host and an embedded target processor. OpenSDA software includes a flash-resident USB mass-storage
device (MSD) bootloader and a collection of OpenSDA Applications. FRDM-KL46Z comes with the MSD Flash
Programmer OpenSDA Application preinstalled. Follow these instructions to run the OpenSDA Bootloader and
change the installed OpenSDA Application to P&E Debug Application that provides debugging and a virtual serial
port all in one application.

Enter OpenSDA Bootloader Mode

Locate the OpenSDA Applications folder in the FRDM­KL46Z Quick Start Package.

Copy & paste or drag & drop the Debug Application
(DEBUG-APP_Pemicro_v106.SDA) to the

BOOTLOADER drive.

Unplug the USB cable and plug it in again. The new

OpenSDA Application should now be running and now
you can debug your application. For more details on
Debug mode or Mass storage application refer to the
OpenSDA user’s guide “OPENSDAUG.pdf”

A removable drive should now be visible in the host file
system with a volume label of BOOTLOADER. You are
now in OpenSDA Bootloader mode.
