    Das soll laut Peter die maximal mögliche Geschwindigkeit der PCIe Schnittstelle sein. Diese Schnittstelle ist nur mit einer Lane an den Prozessor angeschlossen!

    UART *5

    Bitte drauf achten, diese Schnittstelle arbeitet mit Level Shifting, was billige Adapter oft nicht abkönnen. Habe ich hier im Beitrag ausführlich erklärt, mit passenden Adapter, wenn es so wie bei mir nicht funktionierte.
