STM32Cube Programmer 'No STM32 target found' error using b96bf446ve Nucleo board

[punny3dfx]

I tried all the walkthrough's form the internet, but couldn't connect the STM32F446VE i.e. the b96bf446ve nucleo board.

I know form other boards that one can use an external programmer. The ST programmer is the only device that's recognized.

Can someone help me????

Hi @Jan-Georg Krüger​ 

Check the schematics of the Nucleo board (jumpers)

try "connect under reset"

Use STM32 Cube Programmer.

Not exactly a NUCLEO board

https://os.mbed.com/platforms/ST-B96B-F446VE/

Is there an ST landing page for this, or a schematic?

[Sarra.S]

This is the link of the board

Please note that this product is obsolete.

Thank you very much for your kind replies...

I will check Sarras howto with the reset pin...and switch, if I can't get it running, 2 another boead anyway...

Thanks...

This is the message I get, when I connect the board to the PC.

It says: 0 Volt​age.

What is wrong there?

This is an old board without a lot of resources.

Absent a schematic you'll have to trace the circuit, and compare with NUCLEO-64 series boards.

The failure suggests that the ST-LINK/V2 is not seeing a supply, or have connectivity with the STM32 part.

Suggest you review how the board is supposed to be powered, or what other board it expected to sit on top of.

Check jumpers or solder bridges, or if VIN can be powered.

Hello, yea, you were very right. There is for instance the Dragon Board 410c, a SOC development board with Qualcomm processor, that hosts the board. This isn't a standalone board.

So all the problems came from a missing supply.

Thanks and goodby.

Hello, I tried to buy a Dragon Board, but they were out of stock there at Arrow, so anyway.

[punny3dfx]

So is found some at Verical:

[punny3dfx]

Oops...I think these mentioned above are only the cases for the Dragon Boards.

[Tesla DeLorean]

Yeah, 96Boards have about zero traction here, so not clear on the allure.

The block diagram suggests the board can be powered via the Arduino header.

But this doesn't really address what and how you expect to use the board, as I don't imagine there are a lot of examples.

The mbed page perhaps provided most details of pins, etc, and NUCLEO-F446 example might port with effort.

My problem is now solved...I put an Arduino on top of the board, plugged 5V USB power in so the board is now correctly powered up. I have a drive now with about 1,6mbyte of flash. STLink now recognizes the board and the flash memory automaticly

So I'm now okay with my board......................................
