    @hannescam Hallo! Das ist ja schon ein paar Tage her, gut das wir den Screenshot haben. Du könntest genau diese Kernel-Version vom Kamil suchen und benutzen. Da musste man kein Linux Held sein, Kable einstecken - Bild da.

    Ob das mit was Aktuellerem geht, weiß ich nicht. Debian kann man ja so installieren, wie findest Du hier im Forum. Ob Debian die USB-C Schnittstelle nutzt weiß ich nicht. muss man ausprobieren.

    Da für mich die Platinen immer nur ohne Desktop Sinn gemacht haben, habe ich so was immer nur ganz kurz angetestet. Nutze die SOCs eigentlich ausschließlich Headless.

    @FrankM sagte in NVMe SSD Speed auf Kernel 5.0 von Kamil:

    Kurz was zum Nanopc-t4, das war das Board, wo ich damals schon geschrieben habe, wie man da die Wärme weg bekommt!? Ok, bleiben wir beim ROCKPro64 😉

    Hmm .. nix dazu im Forum bei dir gefunden .. nach wärme , nano usw. gesucht ..

    Den Teil verstehe ich nicht. Woher soll er denn das 0.7er Image laden???

    Von seiner SD .. ein bisschen wirr von mir beschrieben.

    Nackter Rockpro, ohne USB-Devices, ohne NVMe, ohne emmc, ..

    Ablauf 1:
    SD Karte mit 0.7er Image (das bisher immer funktioniert hatte) rein -> Rockpro geht an, beide LEDs gehen an (was aber bisher nur die weisse war), kein weiterer Boot-Vorgang.

    Ablauf 2:
    SD Karte mit 0.8er Image (gleiche SD Karte) rein -> Rockpro geht an, perfekter Boot Vorgang.

    Das Monitor "Problem" und das 0.7er scheinen hier ggf. zusammen zu hängen, jedoch - mehr debugging nur mit der RS232 möglich, ggf. Mist im First-Stage-Loader ..

    (Erase SPI , etc. alles hatte nichts verändert ..)

    Wenn jemand richtig Zeit und Lust hätte könnte man sich ja am Armbian nand-sata Script orientieren:

    Da habe ich auch schon mal drüber nachgedacht....

    Ich würde 5$ Patreon Money dazu geben 🙂

    Einen schönen Sonntag.

    Für Bluetooth scheint noch was zu fehlen

    Mal ein Test was der Speicher so kann.
