UART Test:
Open PuTTY or TeraTerm, connect to Serial Port
identified above, set for 115200 baud. Hit Reset (SW1)
and Observe output.
Accelerometer demo-
1) Tilt board on left edge and the Green LED flashes.
2) Tilt board on right edge and the Blue LED flashes.

Introduction to OpenSDA
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-KV31F 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

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

While in OpenSDA Bootloader mode, double-click
SDA_INFO.HTML in the BOOTLOADER drive. A web
browser will open the OpenSDAhomepage
containing the name and version of the installed
Application. This information can also be read as text
directly from SDA_INFO.HTML.
Locate the OpenSDA Applications folder in the
FRDM-KV31F Quick Start Package.
Copy & paste or drag & drop the MSD Flash
Programmer and DebugApplication
(0221_k20dx128_kv31f_0x8000.bin)to the
BOOTLOADER drive.
Unplug the USB cable and plug it in again. The new
OpenSDA Application should now be running and a
FRDM-KV31F drive should be visible in the host file
system.

IMPORTANT NOTE: Follow the “updated an OpenSDA
Application” instructions to update the OpenSDAfirmware
on your FRDM-KV31F to the latest version. It is likely that
the version provided in this package is newer than what
was preprogrammed on your FRDM-KV31F.
Unplug the USB cable if attached.
Press and hold the Reset button (SW1).
Plug in a USB cable (not included) between a USB
host and the OpenSDAUSB connector (labeled
“OpenSDA”). .
Release the Reset button.
You are now running the latest version of the MSD Flash
Programmer and Debug.

Introduction to OpenSDA
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 KV31F MCU. It emulates a FAT16 file system, appearing as a removable drive in the
host file system with a volume label of FRDM-KV31F. Raw binary and Motorola S-record files that are copied to the drive are
programmed directly into the flash of the KL27 and executed automatically. The virtual serial port can be opened with
standard serial terminal applications.

The new application should now be running on the FRDM-
KV31F. And you can program repeatedly without the need
to unplug and reattach the USB cable before
reprogramming.
Program rtc_func.srec example to replace the out-of-box
demo on your FRDM-KV31F.
Locate the Precompiled Examples folder in the
FRDM-KV31F Quick Start Package.
Copy & paste or drag & drop one of the .srec files
to the FRDM-KV31F drive.
Determine the symbolic name assigned to the
FRDM-KV31F virtual serial port. In Windows open
Device Manager and look for the COM port named
“PEMicro/Freescale – CDC 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.
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.
Configure the terminal program. Most embedded
examples use 8 data bits, no parity bits, and one
stop bit (8-N-1). Match the baud rate to the selected
serial test application and open the port.
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: Flash programming with the MSD Flash Programmer is currently only supported on Windows operating systems.
However, the virtual serial port has been successfully tested on Windows, Linux and Mac operating systems.
