3. Building and programming a project

The \STM32Cube_FW_WL3_V1.0.0\Projects\NUCLEO-WL33CC\Demonstrations\Command_Line_Interface\CLI project (on GitHub) demonstrates the basics and can be used in further steps.

3.1. Building and programming with STM32CubeIDE using onboard ST-LINK

• Open the project by doing one of the following:
  • Double-clicking the .cproject file in \STM32Cube_FW_WL3_V1.0.0\Projects\NUCLEO-WL33CC\Demonstrations\Command_Line_Interface\CLI\STM32CubeIDE
  • Importing the path by running STM32CubeIDE (File -> Open Projects from File System), as shown by the image below:
    
    
    
    
    
• Build the project (Project -> Build project or click the icon, as shown by the image below):
  
  

• Program the project (Run -> Run As -> STM32 C/C++ Application, as shown by the image below):
  
  
  
  
  
• In the pop-up window (as shown in the image below), click OK to program the CLI firmware onto the board.
  
  
  

3.2. Building and programming with Arm^® Keil^® using onboard ST-LINK

• Make sure that the patch was installed (STM32Cube_FW_WL3_V1.x.x\Utilities\PC_Software\Keil.STM32WL3x_DFP.1.0.0.zip)
• Open \STM32Cube_FW_WL3_V1.0.0\Projects\NUCLEO-WL33CC\Demonstrations\Command_Line_Interface\CLI\CLI.uvprojx
• Build the project (Project -> Build Target (F7), as shown by the image below):
  
  
  
  
  
• Program the board (Flash -> Download, as shown by the image below, or launch a debug session, which also triggers download):
  
  
  

3.3. Building and programming with IAR Embedded Workbench using onboard ST-LINK

• Make sure that the patch was installed (STM32Cube_FW_WL3_V1.x.x\Utilities\PC_Software\EWARMv9_STM32WL3x_V1.0.0.zip)
• Open \STM32Cube_FW_WL3_V1.0.0\Projects\NUCLEO-WL33CC\Demonstrations\Command_Line_Interface\CLI\EWARM
• Build the project (Project -> Make (F7), as shown by the image below):
  
  
  
  
  
• Download the project (Project -> Download -> Download active application, as shown by the image below, or click Download and Debug):
  
  
  

3.4. Connecting to the device using STM32CubeProgrammer and ST-LINK

STM32CubeProgrammer can be used to view the device memory, download firmware to the device, upload the device memory to a file, manage the device option bytes, and much more.

In this case, STM32CubeProgrammer can be used to download the built binary (from either of the IDEs) to a device or multiple devices.

To do so:

• Launch STM32CubeProgrammer and connect to the device (reset mode must be set to Software reset, other settings can be left at default value)
  
  
  
  
  
• Open the compiled CLI binary from either of the IDEs:
  • For STM32CubeIDE: \CLI\STM32CubeIDE\Debug\CLI.elf (hex generation can be enabled in the project settings)
  • For Arm^® Keil^®: \CLI\MDK-ARM\Release\Exe\CLI.hex or CLI.axf
  • For IAR: \CLI\EWARM\Release\Exe\CLI.hex
• Depending on the binary, the address may need to be set to 0x1004 0000 manually.
  
  
  
  
  
• Disconnect the device
