Usage instructions

The NXP SDK is an NXP-specific software abstraction layer that provides interfaces to the device-specific peripherals. The steps to create a microcontroller application that uses MDK-Middleware and the NXP SDK are:

1. Create project and add software components
2. Copy source files to project
3. Configure the project
4. Configure pin and clock settings
5. Configure CMSIS-Drivers
6. Add user code
7. printf retargeting
8. Build and debug the application

Assumptions

The instructions assume the following:

• The device you have selected is called <selected_device>, for example MIMXRT1052DVL6B
• The installation directory of this software pack is called <PACK_root>, typically C:\>Keil_v5\ARM\PACK\Keil\iMXRT105x_MWP\2.0.0
• Your project directory is called <project_dir>

Important notes

The EVK board might be initially pre-loaded with an application which disables debug. In such case it is necessary to erase the Flash before using the board. Follow this procedure:

• Change SW7 switch position to different than initial which is: OFF, ON, ON, OFF
• Copy the CMSIS-RTOS Blinky project from Pack Installer and build the Release target in µVision
• Connect the USB cable to J28 connector (CMSIS-DAP)
• Reset the board by pushing button SW4
• In µVision, click on Flash -> Erase soon after releasing SW4 push-button
• After erasing of the Flash has finished, power-off the board (disconnect from J28)
• Set switch SW7 to initial position
• Connect USB cable to J28. The board is now ready for debugging.
