This article proposes to address the creation of a simple hello-world application with STM32CubeIDE.
1. Create GtkHelloWorld user space project[edit source]
In the context of a Cortex®-A7 sub-project, called here MP157C-DK2_CA7, right-click and select Create a userspace Project..
HEre, an Executable 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. Update GtkHelloWorld project sources and properties[edit source]
Hereafter we update main.c source code with gtk_hello_world.c as defined in Create a simple hello-world application article.
The proposal to reference the Gtk library is to use the pkg-config command to update the compiler and linker flags, just like it is done in the Makefile of article Create a simple hello-world application. This properties update is done inside menu GtkHelloWorld properties: C/C++ Build > Settings > Tool Settings.
- main.c update and C flag: `pkg-config --cflags gtk+-3.0`
- linker flags update: `pkg-config --libs gtk+-3.0`
- Now you can build GtKHelloWorld project, right-click on it and then Build Project.
3. Preparing Debug Configuration[edit source]
Your target must be Linux booted and network connected. Please, start Target Status widget on the bottom right and check for the green light. Remember that Linux console cannot be shared outside STM32CubeIDE: butterfly icon.
Please also check How to set up proxy and P2P Ethernet connection with STM32CubeIDE if you are in that case.
4. Debug Configuration[edit source]
Select your project, right-click Debug as... > Debug Configurations, then select STM32 Cortex-A Remote Application'.
In the main tabulation, the default Connection proposed is "MPU SSH", corresponding to the target IP address discovered by Target Status. The default destination directory is /home/root.
5. Debug launch[edit source]
Click Debug :
- GtkHelloWorld is downloaded to the target,
- GDBServer is launched on the target,
- GDBClient is launched on the workstation and can exchange via network with GDBServer,
