If you develop for STMicroelectronics boards, you’ll be happy to know that CLion integrates with STM32CubeMX:
Debugging with the Open On-Chip Debugger is supported by CLion. Use the new Run/Debug configuration template, ‘OpenOCD Download and Run’ to debug on your microcontroller.
If you work with a STM32CubeMX project in CLion, an OpenOCD Run/Debug configuration will be created for you automatically.

If it’s possible to debug on the microcontroller of your choice with a GDB Server, you can do it from CLion using a special Embedded GDB Server Run/Debug configuration. It covers OpenOCD, ST-Link GDB Servers, Segger J-Link GDB Server, QEMU, and many other specific GDB Servers.
Create a configuration, providing a path to GDB Server, arguments to run the server, and other appropriate settings, and you are all set and ready to debug on-chip from CLion!
When debugging on-chip, it’s crucial to have the ability to view the peripherals. In CLion, this view is available for two types of Run/Debug configurations: Embedded GDB Server and OpenOCD Download & Run. In both cases, a Peripherals tab appears in the debug tool window when you start debugging. Load the appropriate .svd file for your board and select the active peripherals you need to see.
