Hi,
I wonder in which state are the GPIO lines of STM32F407VG BEFORE loading program to flash memory.
Thanks 🙂

This depends on the GPIO port: Please check the relevant section GPIO registers in the reference manual for the respective family.
You will find the reset values of GPIOx_MODER, GPIOx_PUPDR etc, which are active until changed by the initialization.
