The same utility can downgrade the board back to ST-Link. To perform this upgrade you need a Windows computer (VirtualBox or VMWare might help) and Segger upgrade utility. In this case, Nucleo onboard st-link jumpers must be removed, and the probe must be connected directly to MCU pins. Of course, if you have Segger J-Link device, you can use it according to the license terms and just skip board upgrade. Note that the upgrade license allows you to use this upgrade for ST evaluation boards only production use is prohibited.
Now it’s possible to upgrade onboard ST-Link debugger to full-featured J-Link debug probe. Luckily, there is a company called Segger that produces its own JTAGs and a debugger on top of that. CLion has dbg support, but unfortunately there is no support for remote dbg, and it is not possible to use CLion’s internal debugger for any embedded development yet (please vote). It case of ST development boards (both EVAL, Discovery or NUCLEO series), there are on-board ST-link compatible JTAGs. To debug firmware, JTAG probe is required as well as remote dbg support for it. This could be done through the bootloader (USB, UART, I2C, SPI, OTA etc.) or through the hardware JTAG probe. In case of embedded, the program (firmware) should be downloaded into the target chip, and then run (in most cases the MCU is just reset after download). In case of desktop, the program is just run directly or under dbg for debugging. The main difference between desktop and embedded programming is how to run or debug the program. Let’s use a Linux-based (Ubuntu 16.04) computer for this development. This is ARM Cortex M4+FPU MCU, 72MHz, 64(RAM)/512(ROM) kB of memory. Let’s try to program something for one of them with CLion.Ī good target platform is NUCLEO-F303RE – a development board for STM32f303RE MCU. Many of them are quite powerful and at the same time cheap and relatively easy-to-program. One of the most popular microcontrollers (MCU) nowadays is a huge family of ARM Cortex-M compatible processors, based on the 16/32bit ARM kernels, but made by different companies.
Embedded programming here means no operating systems, clipboards or other processes. Although CLion in its current state is not targeted at embedded development, it’s still possible to use it for this purpose. IntroductionĬLion is a relatively new IDE for C/C++, based on very popular IntelliJ Platform, and hopefully it inherits most of the nice features of IntelliJ IDEA like code highlighting, autocompletion, refactoring, and analysis.
