Get Started with the OM13588

1– Import the MCUXpresso SDK

1. Open up the MCUXpresso IDE

2. Switch to the Installed SDKs view within the MCUXpresso IDE window

3. Open Windows Explorer, drag and drop the FRDM-KL87Z-OM13588 SDK (unzipped) file into the Installed SDKs view.

4. When the following pop-up appears, click OK to continue the import

5. The installed SDK will be displayed in the Installed SDKs view as shown below:

2– Build an Example Application

The following steps guide you trough opening the usb-pd example.

6. Find the Quickstart Panel in the lower left-hand corner

7. Then click on import SDK examples(s)...

8. Click on the frdmkl28z_om13588 board image to select that you want to import an example project that can run on that board, then click Next.

9. Use the arrow button to expand the usb_examples category, expand the usb_pd section, then select one of the projects usb_pd_bm bare metal or usb_pd_freertos freertos. To use the UART for printing (instead of the default semihosting), clear the “Enable semihost” under the project options. Then, click Next.

10. On the Advanced Settings wizard, clear the checkbox Redirect SDK “PRINTF” to C library “printf” to use the MCUXpresso SDK console functions for printing instead of generic C library ones. Then click on Finish.

11. Now build the project by clicking on the project name and then click on the Build icon.

12. You can see the status of the build in the Console tab.

Run an Example Application

13. With the project compiled, you can now flash it to the board and run it.

14. Make sure that the FRDM-KL28Z board is plugged in through the SDA USB port, and click on Debug ‘frdmkl28z_om13588_usb_examples_usb_pd_bm’ [Debug]

15. MCUXpresso IDE probes for connected boards and should find the USB – OpenSDA DAP Link debug probe that is part of the integrated OpenSDA circuit on the FRDM-KL28Z. Uncheck the Remember my selection. Click on OK to continue.

16. The board gets flashed with the firmware, and the debugger starts.

17. Click the Terminate button and disconnect the device

The USB Type-C PD stack needs one provider and one consumer, repeat steps 1 through 6 to program the second board.

Build the MCUXpresso SDK

1. If not already done, open the desired example application workspace. Most example application workspace files can be located using the following path: install_dir/boards/sdk_board_name/example_type/application_name/rtos/iar/rtos/application_name/example_type/sdk_board_name/install_dir

Using the usb_pd demo as an example, the path is: install_dir/boards/frdmkl28z_om13588/usb_examples/usb_pd/bm/iar/usb_pd_bm.eww/install_dir

2. To build the application, click the Make button, highlighted in red below.

3. Double check at the Build message window that the build complete without errors.

Run an Example Application

1. The FRDM-KL28Z board comes loaded with the DAPLink debug interface from the factory. If you have changed the debug OpenSDA application on your board, visit www.nxp.com/opensda for information on updating or restoring your board to the factory state.

2. Connect the development platform to your PC via USB cable between the "SDAUSB" USB port on the board and the PC USB connector.

3. Click the "Download and Debug" button to download the application to the target.

4. The application is then downloaded to the target and automatically runs to the main () function.

5. Click the Stop Debugging button and disconnect the USB cable

The USB Type-C PD stack needs one provider and one consumer, repeat steps 1 through 6 to program the second board.

1. Align the pins on the USB Type-C Shield to the headers of the FRDM-KL28Z so that the two boards mate correctly and press them together.

2. Change USB PD Shield jumpers J11 and J12 to the 2-3 position.

3. To monitor VBUS changes, connect a voltmeter between J5 and J8 pin 6 at the USB Type-C Shield.

4. Attach the FRDM-KL28Z OpenSDA USB cable.

5. Power the USB Type-C Shield by connecting the 9V power source to J1 jack.

6. Open a terminal application on the PC (such as PuTTY or TeraTerm) using the debug COM port you determined earlier. Configure the terminal with these settings:

• 115200 baud rate
• No parity
• 8 data bits
• 1 stop bit

7. Press the Reset button; the following message should appear on the terminal.

8. Repeat steps 1 through 6 for the second FRDM-KL28Z / USB Type-C Shield setup.

9. Connect a USB Type-C cable between the two boars, one works as a sink and the second one becomes the source. To identify which is which go to the terminals.

10. Write ‘0’ at the sink terminal. The following menu will be printed in the debug console.

11. Input ‘c’ to make a 9 V request. After the request is complete, the voltmeter shows approximately 9V.

1. Open MCUXpresso IDE

2. Click Import SDK Example(s)... from the Quick Start Panel.

3. Select the FRDM-KL28Z-OM13588 board in the Import Wizard. Then, select Next.

4. Use the arrow button to expand the usb_examples category, and then click the checkbox next to usb_pd_sink_battery_bm to choose that project. Select UART as the SDK Debug Console under the project options. Then, click Next.

5. On the Advanced Settings wizard, clear the checkbox Redirect SDK “PRINTF” to C library “printf” to use the MCUXpresso SDK console functions for printing instead of generic C library ones. Then click on Finish.

6. Now build the project by clicking on the project name and then click on the Build icon.

1. Open the MCUXpresso Config Tool.

2. In the wizard that comes up, browse to the place where the MCUXpresso SDK previously unzipped, and then select the “Clone an example project” radio button and click Next.

3. Choose one of the USB PD sample projects to clone. For this example, the following instructions show how to clone the usb_pd_battery project. Write battery in the filter box and then select the usb_pd_battery/freertos project. Then click Next.

4. Then select the directory you want to place the cloned project, give it a name, and choose the IDE to use. Note that the toolchains listed are the same used in the SDK builder. Then click on Finish.

5. After cloning go to the select directory, and open the project for your IDE. Import, compile, and run the project as done in previous sections.
