    @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.

    Hallo FrankM,
    schade das Du mir nicht weiter helfen kannst, aber danke für Deine schnelle Antwort.
    Mit dem Bugreport kenne ich nicht aus, bin noch leihe.

    Einen schönen Abend noch.

    Mal ein Test was der Speicher so kann.

    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)
