Setting #define MOTHERBOARD BOARD_BTT_SKR_MINI_E3_V1_2 and #define SERIAL_PORT 1 is enough to trigger this minor warning.

Issue is stm32 implementation of analogInputToDigitalPin (uint32_t) vs marlins pin definition (int32_t)

Code in question was added in https://github.com/MarlinFirmware/Marlin/pull/27219

[ellensp]

code already has

pragma GCC diagnostic ignored "-Wnarrowing"

so add this line under it

pragma GCC diagnostic ignored "-Wsign-compare"

I can confirm same problem happening on Longer LK1 (Alfawise U20). Visual Studio Code does compile it showing this error, but does produce bin image. Once the printer is flashed with the resulting image it gets stuck in the "Load EEPROM defaults" screen touchscreen not responding.
