Using ST-Link of STM32F4 Discovery Board for programming STM32WB

[Nico3]

Hello,

I am new to STM32WB series. I have designed my custom board, but I can not upload the program. I am using ST link on  STM32F4 Discovery board but I sees "Target no device found".  

Please confirm if we can use Stink on STM32F4 Discovery board to upload the program or not. 

Thanks

Hello @Nico3 

I've just tested this using the STM32F4DISCOVERY and the Nucleo-WB55CG and I can confirm that it should work fine. I think this problem may be on your HW design. 

PS: If you want to use the embedded ST-Link of the STM32F4DISCOVERY to program your STM32WB based design, you can use the Connector CN2 pins after taking off the 2 jumpers of the CN3.

Best Regards.

As @STTwo-32 says, it should work.

So the problem must be in:

• your custom board - design and/or implementation;
• your configuration of the Discovery board;
• your connections between Discovery & custom boards;
• any combination of the above

Please see How to write your question to maximize your chances to find a solution - in particular:

• Provide schematic of your custom board
• Provide schematic of Disco connection to your custom board 
• What tools are you using (including versions)? Show the error message(s) you get
• Some good, clear photos of your setup may help

Please note I am able to program STM32WB MCU now.  The issue was with soldering. Most likely one of connection was dry.   It is really challenging to manually solder QFN package.

Great - so please mark that as the solution:
