Convert to H6 (64bit)

[Hazeline2018]

I'm working on OPi Lite 2 (H6, 64-bit based) board and trying to port this code into H6 env. However, no luck so far. I've modified the base addresses to match H6. However, cannot get the designated GPIO pin to work. I tried reading back the port control register, but always got 0x0 value, even the default value, according to the DS, should be 0x7777_7777 or any non-zero value. I'm wondering if this has to do with the 32-bit addressing vs 64-bit. Can anyone point me how to proceed? Really appreciated!
