I see the possible reasons, but I don't have an IoT board on hand to test right now. The display is turned on in u-boot and it uses pins like PH and PJ. You can try disabling the u-boot display to see if it has any effect. Go to https://github.com/OpenNuvoton/MA35D1_u-boot-v2020.07/blob/master/arch/arm/dts/ma35d1.dtsi and search for "display".

It has been confirmed that the GPIO failure was caused by u-boot enabling display, which modifies MFP of many GPIOs including H and I. To fix this issue, we have disabled u-boot display by default and updated it on GitHub. Please update your u-boot version.
