Vorserienmodell

ROCKPro64
  • Dran denken, wir haben hier ein sehr frühes Modell auf dem Tisch. Hier ein paar Info's, die ich nicht vergessen möchte, deswegen schreibe ich das hier auf. 🙂

    Probleme

    • (16:02:35) tllim: 1. Lacking POWER LED. This is miscommunication between engineers and layout engineer drop this LED. This will put back on netx batch
    • (16:03:54) tllim: 2. There is a small yellow tape near LCD DSI connector. This prevent the LCD flat ribbon cable touch the surronding resistor and caught short circuit. This will improve on nex batch.
    • (16:04:24) tllim: 3. There is no RECOVERY button staff. Not sure whetehr we will staff on next batch
    • (16:08:32) tllim: the othe rtwo LED also a bit bright, we will dim down on next batch

    Boot

    Zur Zeit unklar, testen!!

    • (16:22:52) lukasz: tllim: but wont the SD boot Android image just work from eMMC with dd ?
    • (16:24:30) tllim: @lukasz, for Allwinner yes, for ROCKChip no

    Recovery-Button nötig?

    • (16:47:26) frankm: From forum "When used properly, it puts the board into Loader Mode, which is a special mode in the bootloader which allows data to be written/read directly from the eMMC chip, over a USB cable to a computer." I think i don't need this. Will see...
    • (16:50:48) tllim: the ROCKPro64 and ROCK64 using same method

    .... wird ständig erweitert

    Quelle: IRC-Chat

  • [V] ROCKPro64 incl. PCIe SATA-Karte

    Kurzer Test, ok ist was länger geworden 🙂 Mit Debian Buster Minimal habe ich es nicht hinbekommen 😞 Das soll aber nicht heißen, das es nicht geht. WLan auf der Konsole ist nicht meine Stärke. Ok, dann Desktop.

    Installiert, kurz WLan 5G aktiviert, eingeloggt. Netzwerkkabel entfernt. Firefox angeworfen, Rammstein Viedo in 1080p angeworfen. Läuft alles einwandfrei.

    Und PCIe NVMe SSD geht auch 😉

    Das Desktop System ist mittlerweile richtig gut zu benutzen. Aber ich bin verwöhnt, mir ist das immer viel zu langsam. Das soll aber niemanden davon abhalten, sich das mal anzusehen. Je nach Einsatzzweck sicherlich interessant.

    Kurzes Update

    https://github.com/ayufan-rock64/linux-build/releases/download/0.8.0rc10/stretch-openmediavault-rockpro64-0.8.0rc10-1125-armhf.img.xz

    Startet 🙂 Incl. WiFi & PCIe NVMe SSD

    War aber nur ein ganz kurzer Test!!

    Ergänzung

    Eine andere SATA-Karte und eine Riser-Karte mit angeschlossener GPU startet nicht.

    Mal ein Test was der Speicher so kann.
