Hi everyone, I want to use other LCD-TFT screen with the STM32MP15X-EVAL board but there is something strange with this connector. There are two duplicated pins, R5 and R7 , but looking for on the board documentation, I can't find anything related with this. What is these pins function?

Thanks in advice.

    Hi @JManu.1 Cabrera Campos​ ,

    This duplication was intended for internal tests purposes in order to give compatibility with various internal boards shared with other STM32 products.

    On your side, you could safely skip pin 2 and 7.
