I have a libopencm3 project for STM32F411 which I cannot debug properly since some time.
It starts as usual, comes to a brakepoint but in the asembly list, not in the C source. Stepping around works fine.
Looks like:
Previously, the Language shows “Disasembly”, here I switched to C.
The debug-console does not show anything unusual:
Reading symbols from C:\Users\krunoslav.ostrouska.TELE\Documents\PlatformIO\Projects\MotorController2_�C\.pio\build\genericSTM32F411CE\firmware.elf...
done.
