I have a NUCLEO-F207ZG board and STM32CubeProgrammer v2.7.0. I would like to use the embedded bootloader located in system memory.
So, first I activate bootloader mode pulling-up pin 138 (boot0) of the MCU. Then, in order to verify this first operation, I connect NUCLEO-F207ZG board to STM32CubeProgrammer via ST-LINK/V2-1 interface. The board connect succesfully and if I browse in the MCU Core menu I can see the Program Counter value is in the system memory range address.
My next step is to disconnect NUCLEO-F207ZG board from the STM32CubeProgrammer and to select the UART interface (configuration is shown in the attached image) . When I click the Connect button, I get the following message error (see also the attached image):
Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...
I tried resetting the board, but it didn't solve the problem.
Could you tell me please how to solve this problem, please?
Thank you.
Best regards,
Riccardo

Hi @RConf.1 ,
To connect this NUCLEO-F207ZG board in bootloader mode via UART interface you need to :
-Make sure that Boot0 is connected to VDD and Boot1 is connected to GND
-Make sure to connect RX/TX pin , you can use PB10 (USART3 in transmission mod) and PB11 pin(USART3 in reception mode )
-Select the appropriate port
You can refer to AN2606 document for UART connection and Board schematic for pins .
