STM32WB15CC Custom Board Target No Device Found

[YunChance]

Hi.

I'm having hard time with my custom board based on STM32WB15CC.

I referred Nucleo-WB15 schematics but using ST-Link V2 instead of ST-Link on Nucleo Board.

I had an experience of STM32F411 so I thought this time I also can do it by STM32WB15. However after I finished soldering ​and I'm just seeing 'No device found on target'.

Is there anyone can advice me of my schematics?

If schematics are not right way, I'm going to fix it. However, if schematics are right, maybe it will be soldering problem. I tried 3 boards to find my device by ST-Link but all of them are failed.

Hello @YunChance​ ,

Try using latest release of STM32Cubeprogrammer.

Make sure to upgrade the ST-LINK/V2-1 firmware.

Check if all jumpers are correctly configured.

Try connect mode to "Under reset".

Thanks for reply.

I'm using latest STM32CubeIDE and ST-Link firmware is also the latest version.

Try connect mode to "Under reset".

--> What should I have to try connect mode to "Under reset"??

Default communication is SWD, your schematics show JTAG...

Try in CubeIDE config connection switch to JTAG.

And IDE only isnt capable flash and configure all WB dual cortex parts.

You need install STM32CubeProgrammer too.
