There are differences at register level:
What register settings are you using ?IMPORTANT
The pad reset state is different from RP2040, which only disables digital inputs on GPIOs 26 through 29 (as of
version B2) and does not have isolation latches. Applications must enable the pad input (GPIO0.IE = 1) and disable
pad isolation latches (GPIO0.ISO = 0) before using the pads for digital I/O. The gpio_set_function() SDK function
performs these tasks automatically.
