Here below image of the MCU on my two nucleo boards. I tried to program the MCUs using SMT32CubeProgrammer and USB-TTL converter connected to USART1 via pin PA9 and PA10, BOOT pin tied to 3V3. I press the reset button, then try to connect F070 MCU but it don't answer.
I have used same setup with SMT32F072RBT and it works well.
Where I wrong? Any suggest to reach my goal?
I'm developing a new board based on F070 and I need to use the MCU internal bootloader.
