STM32F3 DISCOVERY BOARD -Target not found

[keerti]

My STM32F303VCT6 discovery board is not connecting with my STM32CUbeIDE

STM32CubeProgrammer gives a "Error: No STM32 target found!" 

I'd appreciate any suggestions about how to fix this issue before I try rolling back the firmware on the debugger.

Here's the error I get in the CubeIDE Console window

STMicroelectronics ST-LINK GDB server. Version 7.5.0

Starting server with the following options:

Persistent Mode : Disabled

Logging Level : 1

Listen Port Number : 61234

Status Refresh Delay : 15s

Verbose Mode : Disabled

SWD Debug : Enabled

Target no device found

 

Error in initializing ST-LINK device.

Reason: No device found on target.

 

Here's the error that pops up the CubeIDE "Problem Occurred" window

Error in final launch sequence:

Failed to execute MI command:
target remote localhost:61234

Error message from debugger back end:

Just try: set it to openOCD , adjust options.

Then try debug.

Thanks! Now it’s working. I’ve shorted the ST Link in the board
