How to connect NUCLEO STM32WB55 onboard programmer to STM32F411 board ?

[GS2]

Hello,

Does anybody knows - are 4 wires enough for programming:

STM32F411CEU6 module      JP5 of the NUCLEO-WB55RG

GND                                        <---- T_VDD

SWSCK                                    ??? SWO

SWDIO                                   <---- SWCLK

3.3V                                        <---- SWDIO

                                                ??? NRST

                                               <---- GND

This is not working:

Error: fail to erase memory
Warning: Connection to device 0x431 is lost.

Hello @GS2 

Are you having a Nucleo or a discovery board. If a nucleo, i'm preparing an FAQ about that and i will provide you details this monday. If a Discovery, i will try to check and get back to you on Monday. Please tell me your board.

Best Regards.

Thank you STTwo-32,

Yes, NUCLEO STM32WB55 onboard programmer and black pill STM32F411 dev board, nicknamed the “Black Pill”.

To enable bootloader:
Used the onboard BOOT0 and NRST button to put the board into bootloader mode:

1. press and hold the BOOT0 button
2. press and release NRST (reset) button to power cycle the processor
3. release BOOT0 button

Now I can download the code and debug it !!!
