How to build and develop

A: Build & Develop on CLion

If you are a CLion user, then everything becomes easier. Open stm32f769xx.ioc in CLion and follow CLion embedded development tutorial step by step, you can build and download your program with just a few clicks.

B: Build & Develop via CMake

Step 1: Build via CMake

To build your program with CMake, please make sure you have all required tools installed and configured properly, and avoid using version which has issue posted by CLion team.

Once you have all the required tools, you can build your program via CMake. Type the following command in current source code folder

cmake --build cmake-build-debug --target stm32f769xx.elf -- -j 3

If the build is successful, you will find the excutable stm32f769xx.elf in cmake-build-debug folder.

Step 2: Run/Debug via OpenOCD

Once you get the excutable stm32f769xx.elf, you can download it to your device via OpenOCD. You can find more information about OpenOCD here.

To download your program, type the following command in current source code folder

openocd -f stm32f769i-disco.cfg -c "tcl_port disabled" -c "gdb_port disabled" -c "tcl_port disabled" -c "program cmake-build-debug/stm32f769xx.elf" -c reset -c shutdown

If nothing goes wrong, OpenOCD will give the following message
