    Hello guys, I am running the really old version of OSW with the VSD-E, small Mige motor and the STM32F4 Discovery board and seperate power supply.
    It has served me great for a long time but after a long pause in simracing because of real life stuff i tried to use it again and realized the discovery board was not responding, so i flashed it again with the mmos firmware.
    During the setup where i tried to set the motor center offset as per usual by clicking the checkbox on the mmos interface, i powered down the whole system, vsde - motor - discovery board. After powering it on again its supposed to have a blue blinking light where u need to move the wheel to the center in order for the board to initialize. I move the wheel, the led turns off as per normal. If i move the wheel to the left by about 45 degrees, the wheel starts spinning like crazy and never stops.

    I tried wiping the STM32F4 Discovery board chip and this stops happening. So it is the STM32F4 Discovery board's fault but i have no idea how ot troubleshoot it.
    Anyone got any ideas on what may be failing here?
