Recover Button

Hardware
  • In der Version v2.0 fehlte dieser Button noch, er war einfach nicht bestückt.

    Wenn jemand den vermisst, zur Not kann man da was dran löten. Sollte machbar sein.

    v2.1

    0_1532793316445_DSC_0039_ergebnis.JPG

    Die Frage, was macht das Ding? Gehen wir mal auf die Suche.....

    Kamil hat auf seiner Release Seite einen Link zu u-boot recovery selection

    Kamil erklärt das so

    ayufan: introduce recovery button mode selection

    Press and hold recovery button to choose suitable boot mode.
    When given mode is selected release the button.
    Each mode exposes device over USB-OTG and can be connected via USB A-to-A cable

    1 blink: share eMMC or SD as virtual disk
    2 blinks: enter fastboot (Android's)
    3 blinks: enter RockUSB download mode
    4 blinks: enter MaskROM download mode

    Ob das so funktioniert kann ich nicht sagen, da ich nicht 100% weiß wofür das ist.

    Spekulation

    An die USB-C Buchse kann man ein USB A-to-A Kabel anschliessen, damit kann man dann mit verschiedenen Programmen auf das Board zugreifen.

    Für Entwickler vermutlich total wichtig, denke ich das es für den durchschnittlichen Anwender unwichtig ist.

  • Ich hab das mal ausprobiert.

    Den Recover Button so lange drücken, bis folgendes erscheint.
