P-NUCLEO-WB55 Error in initializing ST-LINK device. Reason: No device found on target.
Hi,
I am very new to this topic and facing some problems with my P-NUCLEO-WB55 i couldn't solve by myself...
After previously flashing it with a simple program i've powered the board over the Vin and GND with an external power supply (max. 7-12V). Then I put the Jumper back on USB STL and connected it via USB to my Computer just as i also did earlier where it worked..after running even an empty program it says:
"Target no device found
Error in initializing ST-LINK device.
Reason: No device found on target.
Error in final launch sequence:
Failed to execute MI command:
target remote localhost:61234
Error message from debugger back end:
localhost:61234: Connection timed out.
Failed to execute MI command:
target remote localhost:61234
Error message from debugger back end:

localhost:61234: Connection timed out."
I've already reinstalled the driver of the St-Link.
Trying to connect via the STM32CubeProgrammer leads to the following error:
" Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"
My observations: The COM LED and LED4 are red and the board is getting very hot because it somehow takes ~800mA (when powering it with an external supply it only goes to 7V when consuming 800mA, when only giving the board up to 700mA the Voltage is at 2,8V) - so is it likely that it is a hardware error? - but if so, why?
Are there any suggestions what the issue might be and how to fix it?
Thank you very much!
