Question

STM32WB55 with ST-Link from nucleo STM32F446

Hello,

 

I'm working on project with my own design pcb with STM32WB55.

 

I want to program this processor via ST-Link from nucleo STM32F446. Is there a possible to use this programmer to program another type of STM32 processor? 

 

I'm using STM32CubeProgrammer but when I want to connect to my processor it shows this:

As you can see in Log it things that I want to connect F446 boar, but I have connect WB55.

 

Please is it possible to program WB55 with this ST-Link from nucleo F446 or I need to have original ST-Link?

ST-Link pins are connected correctly to the processor so I dont find any problem (3V3 source is also activated).

 

If you know how to fix it or need more info I will reply asap.

 

Thank you for help!

    Yes - see the User Manual for details.

    It's telling you that the ST-Link is on a Nucleo-F446RE board - but that it's finding no Target at all.

    It's also showing that the supply voltage is only 0.01V.

    Check your wiring!

    Post the schematic of your custom board.

    Some good, clear photos of your setup may help.

    If you disconnect the custom board, can the ST-Link still connect to the STM32F446 on the Nucleo board?

     It's connected like this, yes that was sus the target voltage, but when I measure voltage 3.3V from my pcb goes to st-link so I dont know where is the problem.

     

    Thank you

    You have the Nucleo correctly configured to isolate its STM32F446  from the ST-Link?

    How is your board powered?

    How about those photos?
