GPIO INPUT PA6

[Khansokhua]

Hi, 

  STM407G DISC-1 STMCubeIDE

When I configure PA6 pin as an input with pull-down. In a floating state, I still measure approximately 2.8V.

Do I have to use an external pull-down to make it near to zero?

PA6 is an OUTPUT from the MEMS, U5, LIS3DSHTR, check you don't have a conflict there.
