using the builtin IDE (ADC read) example H7+ ADC on P6 pin, IDE 2.6.9, H7+ on latest firmware3.9.3, when pin P6 is open, or when pin is grounded or when pin is connected to 3.3v rail, the reading is the same, that is a slight fluctuation around the 0.432v reading.
As a side note, the DAC example on P6 works, so i believe the pin is not faulty, also the IDE example for (ADC read_int_channel) works.
I’ll test that and get back to you.
