No STM32 target found

STM32CubeProgrammer settings

Just got a NUCLEO-L476RG and connected to my computer. 

I cannot connect to it with STM32CubeProgrammer or STM32CubeIDE2.0.

I had STM32CubeMX generate some code to blink the LED and haven’t changed any code in IDE.

How to I actually connect to this board?

I have tried changing to hardware reset, holding reset button pushing connect in Cube, then releasing etc.

 

I am able to run Firmware upgrade in Programmer and it says it completes successfully.

 

debug authentication discovery fails also

 

IDE Debug error: (when I connect the board it opens in file explorer automatically)

Found the problem. I had the unit sitting on an old breadboard and either the CN7 or CN10 header pins were apparently lined up enough with the holes to make connection. Everything connects now and code uploaded. Just figured I’d post this stupidly simply fix in case someone else is pulling their hair out like I was.
