![]() ![]() A follow-up post will examine more of the linker’s capabilities. In this post I examine the gnarly problems with the GNU linker and how they are easily solved by the SEGGER linker. Webinar Recording: CLion Ask Me Anything Session, the Embedded Development part.In the previous post, Rolf described some of the progress that we have made on the brand-new SEGGER linker. Using nRF52 with CLion and Tutorial: Using nRF52 With nRF Connect SDK, CMake, and CLion In addition to the web help articles and FAQs, you may want to take a look at these posts on embedded development from CLion blog:ĬLion for embedded development part I, part II, part IIIĪrduino Development with CLion part I, part II Learn moreĬheck out the Embedded Development in CLion FAQs. Flashing the target chip in this case should be done using a specific utility (like Avrdude for AVR). PlatformIO projects can be debugged using the PIO Unified Debugger, with all the debug features available as well.ĭebugging is not supported for the platforms that lack GDB support. After that, your firmware running on-chip can be debugged using the entire set of CLion debug features, which includes memory and disassembly view, peripheral view for ARM devices, and a chip reset action. When you start a debug session, CLion connects the debugger to the MCU and uploads your binary. ![]() You can choose between your toolchain’s GDB or CLion’s bundled GDB (for ARM devices) right in the configuration settings. These configurations allow switching the client debugger. For STM32CubeMX projects, OpenOCD configurations are created automatically. In CLion, there are special run/debug configurations for both options: OpenOCD Download & Run and Embedded GDB Server, respectively. It covers various vendor-specific cases like ST-Link/V2, Segger J-Link, QEMU, standalone OpenOCD GDB server, PE-Micro, and others. Flashing and debuggingĬLion supports debugging on-chip with OpenOCD or GDB Server. If you decide to convert your project into CMake, we recommend that you take our template CMakeLists.txt and adjust it for your needs: fill in the TODO sections and modify the library paths if required. However, all the functionality that CLion provides for embedded development (except for STM32CubeMX and PlatformIO support) is also available in the case of Makefiles, as well as any arbitrary build system configured via custom build targets. Build systemsĬLion fully integrates with CMake and bundles one of the latest CMake versions, so CMake can be considered as the primary build system for your embedded projects. The plugin provides a wizard for creating CMake-based PlatformIO projects, special configurations for debug and upload, and allows running PlatformIO actions from the IDE. Note that CLion does not provide IAR licenses.Īs an alternative which would cover the whole embedded environment, consider the PlatformIO ecosystem supported in CLion via the PlatformIO plugin. CLion's support for the IAR toolchain is available on Windows with MinGW and Linux. You can use the compilers from IAR Systems. The toolchain setup will be similar to the case of ARM (see above). Non-ARM chips compatible with GCC are also supported. Install the toolchain, make sure it’s presented in your system PATH, and set the tools up in Settings | Build, Execution, Deployment | Toolchain.įor STM32 MCUs, STM32CubeMX project setup includes the step of GNU ARM toolchain installation, and CubeMX will generate a linker script and hardware-support libraries for you.įor non-STM32 ARM MCUs, you will need to provide the required libraries and the linker script (which you can obtain from your vendor or create manually using the vendor’s standard examples). Toolchains and compilersįor ARM Cortex-M and Cortex-R MCUs, use the GNU ARM toolchain. Note that some STM32 chips are currently unsupported. ioc projects, and get them automatically converted into CMake. Hardware typesĬLion supports embedded development for any hardware compatible with GCC or IAR toolchains.Ī few examples: ARM-based MCUs like STM32 series, Xtensa ( ESP8266, ESP32), mips32 (pic32), AVR8 ( Arduino), RISC-V.įor the case of STM32 MCUs and boards, CLion integrates with STM32CubeMX. For detailed feature descriptions and setup instructions, refer to the dedicated articles in this section. This page gives an overview of how you can use CLion as your embedded development IDE. ![]()
