Plug It In
1.1 Select a Sensor Demonstration Kit
- Go to Sensor Evaluation Boards and select the desired Demonstration Kit
- Take FRDM-K22F-A8974 Demonstration Kit as an example
1.2 Plug it in
Connect the Sensor Demonstration Kit to the PC via the USB cable between the OpenSDA USB port on the board and the USB connector on the PC.
1.3 Board Settings
All the supported sensor demonstration kits should work “Out of Box” with the FreeMASTER Sensor Tool. These sensor kits do not require any hardware configuration changes. Refer to “Hardware Configuration” subsection of FreeMASTER Sensor Tool GUI to get more details on default jumper settings on the sensor kit.
NXP Freedom MCU boards are supplied with OpenSDA firmware preloaded.
For a smooth ‘Out of Box’ experience with FreeMASTER Sensor Tool, make sure that the latest version of the default OpenSDA boot loader and Firmware application is on the supported Freedom development board. This allows debugging, flash programming and serial communication over a USB cable.
Obtain the latest OpenSDA drivers for FRDM boards from the link below.
OpenSDA Update to the FRDM boards
Locate the section "Download – OpenSDA Bootloader and Application" and select your FRDM Board from the dropdown list. Strictly follow the provided instructions to program the board.
For Windows 10 systems, the older versions of the OpenSDA drivers could get corrupted when the board is plugged on a Windows 10 machine. As a result, many boards might get not detected as an MSD or a COM port on Win 10. The latest versions of the OpenSDA software are compatible with Windows 10 and can be obtained from the link above. The current FRDM-K64F, FRDM-K22F and FRDM-KL27Z boards come with an older version of OpenSDA drivers from the factory and require a mandatory OpenSDA update.
1.5 PC Configuration
The output data from the provided example applications is provided over the MCU UART. This requires that the driver for the board’s virtual COM port is installed on the PC. The board MUST be plugged into the PC before the driver installer is run.
If you have not installed already an Arm IDE toolchain, download and Install the Windows drivers corresponding to the default OpenSDA Application selected above:
Once the Windows Serial Port Drivers are installed on the PC, determine the port number of the board’s virtual COM port by opening the device manager and looking under the "Ports" group.
The demonstration kit is now ready to communicate with the PC.
