I have several STM32 CubeMX / HAL projects and I use EmBitz as IDE. All porjects working fine, including compilation and debugging. There are projects with STM32F103, STM32F205, STM32F207, STM32F405, STM32F429, STM32L476, etc. There is one exception: Execution single stepping is not working with STM32F091 target. Always steps into timer interrupt and never get out. Is there a solution? Thanks.
