    Die externen Antennen sind keine gewöhnlichen U.FL Anschlüsse! Bitte beachten, wenn Ihr euch so Antennen besorgt.

    The ROCKPro64 Wifi/BT module using MHF4 connector not the U.FL type, info located at http://www.cmpter.com/single.asp?id=21

    In future module, we plan to use back U.FL.

    Bootet bei mir weder von USB3-SSD noch von SD-Karte. USB3-SSD -> https://pastebin.com/QAS92sme SD-Karte -> https://pastebin.com/Bsr3WLJ7

    Die Verlinkung hatte ich überlesen, sorry. Es gibt nur eine Handvoll Karten, die im PCIe Port funktionieren. Warum, kann ich dir leider nicht beantworten. Es liegt aber mit Sicherheit an falschen Einstellungen im Kernel und an fehlenden Treibern. Ich habe hier auch eine andere Karte rumliegen, die erzeugt immer nur eine Kernel Panic In diesem Thread steht einiges was geht und was nicht. https://forum.pine64.org/showthread.php?tid=6459

The larger is the buffer, the more significant == == are relative contributions of TLB, L1/L2 cache misses and SDRAM == == accesses.
