C Project build


3 Preparing Debug Configuration[edit]

Your target must be Linux booted and network connected. In order to check it, please, start Target Status widget on the bottom right. Remember that Linux console cannot be shared outside STM32CubeIDE: butterfly icon.

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[edit]

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


5 Debug on STM32 MPU device[edit]

Click 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,
C Project debug
