Hi Michael, Odd. Did you check the defines? How are you verifying it? Have you JTAG-ed it, could it be bad SVD? Have you just printed the value to be set and the result ?

However, setting bit 8 (GPIOIEN) in RCC_AHB2ENR1 seems to be ignored (i.e. GPIOIEN remains at 0). For the other eight IO ports (GPIO[A-H]EN) it works just fine. Any ideas anyone? Thanks! Michael
