P-NucleoWB55 ST-LINK error STM32 target found

[Sjain]

Hi,

I am having a problem with my P-NucleoWB55 development board. When using STMCUBEIDE and trying to run the program, I get the following error.

STMicroelectronics ST-LINK GDB server. Version 7.4.0

Starting server with the following options:

Persistent Mode : Disabled

Logging Level : 1

Listen Port Number : 61234

Target no device found

 

Error in initializing ST-LINK device.

Reason: No device found on target.

I also cannot connect using the STM32Cube Programmer. Received following logs when tried with cube programmer.

I tried all the options suggested in following link but no luck to make it working.

While tried with USB DFU option received an error of "USB device not recognized "
Any ideas what could be happening? It was working previously and all of sudden stop working.

Hello @Sjain and welcome to the ST Community.

I suggest you to verify the position of the JP1 is compatible with the 5V source that you are using or not.

In your case, the Jumper should be on the USB-STL.

Best Regards.
