Oh, sorry for not being clear
What I mean is that my adapter board is not even connecting the CM4's GPIO44 and GPIO45 to the equivalent CM3's pins 82 and 84 (or to any other pins)
My only solution with this board seems to be to connect the I2C devices to GPIO0 and GPIO1 (the other I2C bus) and change the software to grab the joystick changes from there. That's why I was asking if the Freeplay board was maybe exposing them so I could "simply" solder the L2R2 Dual Analog (4 ADC) Add-On Board to them instead of GPIO44 and GPIO45
