This article proposes to manage a static library linked with a Linux® user space application for STM32 MPU.
1. Create a user space static library project[edit source]
In the Cortex®-A7 sub-project context, named here MP157C-DK2_CA7, right-click and select Create a userspace Project...
Here, the Static Library project type, in C language, is selected. Note that the user space project uses by default the SDK version associated to the Cortex®-A7 sub-project.
2. Build[edit source]
- Select your project, right-click and then Build Project.
3. Update myExe project sources and properties to use myStaticLib[edit source]
Hereafter is an updated code for main() to call myStaticLib function say_hello().
You must also reference myStaticLib project inside myExe properties: C/C++ General > Paths and Symbols > References as depicted below.
4. Preparing Debug Configuration[edit source]
Your target must be Linux® booted and network connected. Start the Target Status widget in the bottom right corner and check for the green light. Remember that the Linux® console cannot be shared outside STM32CubeIDE: butterfly icon.
Check also How to set up proxy and P2P Ethernet connection with STM32CubeIDE if you are in that case.
5. Debug Configuration[edit source]
Select your project, right-click Debug as... > Debug Configurations, then select STM32 Cortex-A Remote Application'.
The default connection proposed is "MPU SSH", corresponding to the target IP address discovered by the Target Status widget. The default destination directory is /home/root.
6. Debug: stepping into myStaticLib[edit source]
Click Debug :
- Executable is downloaded to the target,
- GDBServer is launched on the target,
- GDBClient is launched on the workstation and can exchange via the network with GDBServer.
