How to flash to STM32f103c8 using codeblocks?

Question

I am trying to program my STM32f103c8 using STM32Cubemx, code::blocks and CubeMXMakefile.py. The compilation result shows 0 errors and 0 warnings and that flashing was successful but the code (blinking PC13) isn't running on the board.

I installed Stlink by cloning " https://github.com/texane/stlink " repo, and running make on it and checked if it worked by running lsusb and confirmed that "STMicroelectronics ST-LINK/V2" was detected.

i also had already installed the arm compilers for codeblocks and they seem to work as well.

My issue was mainly at first that the code wouldn't flash to the board and when running " CubeMXMakefile.py . " i would get a warning that st-flash is not installed although it was built from running Make on the clone, and when trying to "make flash" i would get an error that st-flash can't be found in "/usr/local/bin". I solved this issue (i think) by manually copying the the st-flash file from the build/release directory in the clone repo to the path mentioned. Now the code compiles with no errors in compiling or flashing but the code doesn't work still.

this is the code, all ofcourse generated by cubemx except for the while block:

Answer 1

try

st-flash reset

I found my MCU not running code after flashing. It worked after resetting manually.

If it does not work for you, try this with openOCD.

Tried with OpenOCD, didn't re-flash the device, just "reset run" - and device started working.
