I tried to build the “blinky2” example from “git clone GitHub - ve3wwg/stm32f103c8t6: libopencm3 and FreeRTOS projects using the STM32F103C8T6 MCU ” with “BluePill” and libopencm3. When the build_type=release in *.ini file, the example is uploaded and works (blinks). When the build_type=debug, the …

On second thought maybe do it differently. Other FreeRTOS implementations do not have this problem in the first case because they directly remap function names to the interrupt service routine names. Have a look at the STM32FreeRTOS integration. stm32duino/STM32FreeRTOS/blob/d6244677735600…

However, same is in the release build. I am lost now.

I found the following topic on internet:
