User space CDT project

This article proposes to manage a Linux^® user space application for STM32 MPU, using the standard Eclipse^® CDT™ wizard.

1 Create a "user space" project

• Open the new C project wizard: File -> New -> Project... C Project.
  

New C project wizard

• In the first window, choose OpenSTLinux SDK

New C project wizard

• Then Next to set up configuration

New C project wizard

• and Next to choose the SDK version

New C project wizard

• To populate this project with file "main.c", first select project, then right-click New -> File -> main.c, and then fill it with some C code.

2 Build

• Select your project, right-click and then Build Project.

3 Preparing Debug Configuration

You can check boot messages via Linux^® console opened with butterfly icon, but remember this console cannot be shared outside STM32CubeIDE (minicom,...). In order to debug user space application, your target must be Linux^® booted and network connected.

In order to check network connection, start the Target Status widget in the bottom right corner of the window.

Target Status - green

Please also check How to set up proxy and P2P Ethernet connection with STM32CubeIDE if you are in that case.

4 Debug Configuration

• Select your project, right-click Debug as... > Debug Configurations.
  
• Then create an STM32 Cortex-A Remote Application debug configuration, and double-click on it.

5 Debug on STM32 MPU device

Click on Debug:

1. Executable is downloaded to the target,
2. GDBServer is launched on the target,
3. GDBClient is launched on the workstation and can exchange via network with GDBServer.

Information

In case of error; check if GDBServer is still running on the target.
