Solved

I recently bought NUCLEO-G474RE and found a problem.

The problem is pin PB4, which is always powered.

It is the same as returning to "STM32CubeG4_Demo_NUCLEO-G474RE.hex".

Do I need to send it in for repair??

How to send??

Hello @aarom and welcome to the ST Community :smiling_face_with_smiling_eyes:.

The PB4 is internally pulled up after Reset.as you can see on the page 72 of DS12288 Rev 6:

"After reset, these pins are configured as JTAG/SW debug alternate functions, and the internal pull-up on PA15, PA13, PB4 pins and the internal pull-down on PA14 pin are activated."

So, this is normal.

Best Regards.

Other functions are currently normal!
It would be better if the pins could be arranged in order!
I can only update the definition using *.h,
Thanks for your reply.
