One hint for everyone: If you want to use GPIOs as input, you should define them as PULLDOWN, since PULLUP is currently mapped to PULLDOWN too. Keep this also in mind when designing your PCBs, ...

Strictly speaking, under limited conditions the GPIOs can be set to pull-up or no-pull inputs, but by default if you set a management-controlled input, it will be configured as a weak pull-down. This restriction does not apply to user project-controlled GPIOs.
