Hi,I used PA12 & PA11 as input gpios(pull-up) in STM32U595VJT6Q ,read the pins are always '0'.The IOs connected NOTHING.I reference RM0456 : I config USBPWREN and VDD11USBDIS bits used the HAL functions before GPIO_Init():HAL_PWREx_EnableUSBHSTrance...

Thanks @SStor I tested it and found that this method is effective.

Thanks @SStor Solved: Problem with Pin A11 on STM32U595VJ - STMicroelectronics Community This method is effective.SET_BIT(PWR->SVMCR, PWR_SVMCR_USV); SET_BIT(PWR->VOSR, PWR_VOSR_USBPWREN | PWR_VOSR_VDD11USBDIS);

Hello，Is the address right? You can get the address at AN2606.I did the same function at STM32F429 with the stdlib.It works sucessfully.#define BootloaderAddress 0x1FFF0000 void JumptoBoot(void) { unsigned char i; /* Test if user code is ...

Hi，I encountered the issue about PA11 and PA12 a month ago. I couldn't find a solution, so I asked our hardware designer to modify the circuit diagram and replace with another GPIOs.:face_with_tears_of_joy: GoodLuck！
