We have a design using the STM32F778. The FS USB works fine with VDD = 3.3V. When VDD = 1.8V, the USB does not work. VDDUSB is connected to 3.3V in both cases. On some boards, the FS USB will be detected by PC as a bootloader but it does not actu...
It looks like I made a fatal mistake by connecting the NRST pin to the PA0 pin on an STM32F778AIY. This is a part with no internal voltage regulator for the core so the PA0 pin acts like a power on reset. This hasn't caused problems with power cyclin...
