    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.

    0.6.60 released

    0.6.60: Fix pcie/nvme/sata support for 4.4, 0.6.60: Fix spi-flash access for 4.4/mainline,

    Ich bin davon ausgegangen, das 0.6.x nict mehr fortgeführt wird, okay - sieht nicht so aus.

    Sollte released werden, ist aber aus irgendeinem Grund gestern nicht passiert (lt. Kamil)

    Bericht der Zeitschrift Make.

    Link Preview Image Bastelrechner NanoPC-T4 und ROCKPro64: Mehr Raspi-Konkurrenz mit Rockchip

    Leistungsfähige Raspi-Konkurrenten setzen zunehmend auf den Chip-Hersteller Rockchip. Zwei neue RK3399-Boards eröffnen die Alternative: kompakt oder günstig?
