Display shows only splash screen

Hi,
I tried to install Klipper for my Ender 6. I selected the following options:

I've got an error: Conflicting definition for constant 'RESERVE_PINS_serial'
I can see in compile_time_request.txt that RESERVE_PINS_serial is declared twice.
I modified src/stm32/t5uid1/serial.c: I replaced all instances RESERVE_PINS_serial with RESERVE_PINS_t5uid1. It compiles now with no error. So I flashed the printer. I flashed the display and now it only shows klipper logo only...
I've connected a RPi with OctoPrint and it works, but I can't use the display. Did I make a mistake?
Thanks for your help.

Thanks for reporting the compilation issue, it should be fixed now.

Your problem seems to indicate a communication issue between your mainboard and screen. You should verify that you have selected the right communication interface for your specific board and that your wiring is correct.

Thank you very much,
In fact I didn't have the good config file in raspberry, there were no t5uid1 section, and I didn't have understood that the display needed the raspberry to work. Now everything is OK.
Have a good day.
