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

    Seit Release 0.10.10 ist das automatische Vergrößern der Root Partition mit drin 🙂

    0.10.10: Support automated resize when booting from nvme

    Einfach das Image auf die NVMe SSD schreiben, ab in den ROCKPro64 und fertig! Nach dem Booten wird die Partition dann automatisch auf die maximal mögliche Größe erweitert.

    Kamil hat das Script auch ein wenig angepasst.

    case $dev in /dev/mmcblk?p?) DISK=${dev:0:12} PART=${dev:13} NAME="sd/emmc" ;; /dev/sd??) DISK=${dev:0:8} PART=${dev:8} NAME="hdd/ssd" ;; /dev/nvme?n?p?) DISK=${dev:0:12} PART=${dev:13} NAME="pcie/nvme" ;;

    Das Resultat bei einer Samsung 979 EVO mit 500GB Speicher

    rock64@rockpro64:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 918M 0 918M 0% /dev tmpfs 192M 5.2M 187M 3% /run /dev/nvme0n1p4 459G 1.2G 439G 1% / tmpfs 957M 0 957M 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 957M 0 957M 0% /sys/fs/cgroup /dev/nvme0n1p3 229M 44M 169M 21% /boot /dev/nvme0n1p2 12M 0 12M 0% /boot/efi tmpfs 192M 0 192M 0% /run/user/1000

    Perfekt. Danke Kamil!

    Das ganze hat einen furchtbar schönen Vorteil. Mal angenommen, ich habe ein NodeBB-Forum in einem Container laufen. Will das Ding updaten und das crasht einfach mal so. Egal, Container stoppen, Container starten und alles läuft wieder.

    Mit dem Commit sichere ich mir dann den Zustand nachdem ich weiß, das alles klappt 🙂

    Mal ein Test was der Speicher so kann.
