pin |
Description |
|
JP5 |
1-2 |
1-2 shorted (default setting): Sets target MCU to DCDC mode. This mode is the recommended configuration. |
|
JP5 |
3-4 |
3-4 shorted: Sets target MCU to LDO mode. |
External power configuration (KW47-M2)
Enable KW47-M2 by supplying power through J9 connector:
Note: When using DCDC or LDO mode, it is recommended to supply P3V3_DUT power rail only.

pin |
Description |
|
J9 |
5 |
Use this pin to supply P3V3_DUT power rail with 3.3V. To get KW47-M2 up and running, it is recommended to set KW47 to DCDC mode and supply P3V3_DUT only. |
|
J9 |
3 |
Use this pin to supply P1V8_LDO power rail with 1.8V. This power rail is intended for an accurate control of VDD_RF power domain, but it is not necessary. |
|
J9 |
1 |
Use this pin to supply P1V1_EXT power rail with 1.1V. This power rail is intended for an accurate control of VDD_CORE power domain, but it is not necessary. |
Installing LinkServer software in your PC
To program the KW47-M2 for the first time, you will need to download the LinkServer software and follow the following steps to install it on your PC.
- Download the installer for LinkServer distributed via nxp.com.
- Run the LinkServer installer. Accept the license agreement by clicking on the checkbox in red. Then click the “Next >” button. See the picture below.
- Click “Next >” in the following installation steps that refer to the destination folder where the software will be installed. The following window summarizes the installation information. Click the “Install” button to start the installer.
- Once the Link Server software has been installed successfully, you can close the installer by clicking the “Finish” button.
Programming the NBU in the KW47-M2 board
The following steps guide you to program the NBU software for the KW47-M2
- Place a jumper in the JP4 header while holding pressed the reset SW on the module board, attach the USB connector J8 (FTDI connector) to your computer. Then, release the reset SW after you plugged the USB cable on your computer.
- Verify what COM Port was assigned to your KW47-M2 board. You can check the COM Port assigned in the Windows “Device Manager” program. Search for “Ports (COM & LPT)” and save the COM Port number. In this example the COM Port assigned was “COM19”
- Navigate to your computer to the MCU-Link installation folder. The default installation path is located at “C:\nxp\LinkServer_25.3.31\MCU-LINK_installer
- Locate the “bin” folder and open it. Run the script “blhost” within a windows command prompt.
Type “blhost.exe -p COMX write-memory 0x48800000”, drag and drop the NBU binary file. When the process is ready you will see the response status "success"
