What & Why

ROCK 5T FAQ has two issues around power and boot troubleshooting:

  • Old Q4 says ROCK 5T has a dedicated TYPE-C power port and walks through USB PD negotiation. This is wrong: ROCK 5T is powered by a DC 12V adapter (or PoE). The on-board USB Type-C port is only for OTG/data/Maskrom and does not power the board. Source of truth: docs/rock5/rock5t/getting-started/power-supply.md lists "DC 12V 适配器" as the supported power input.
  • Old Q5 (now renumbered to Q4) tells the user to plug USB-C into the PC and watch for a green LED, but it never says to connect the DC 12V adapter. Without DC 12V the board has no power, so the LED will never light up and the Maskrom check is meaningless.

This change:

  1. Removes the obsolete Q4 (USB PD / Type-C power) entirely.
  2. Renumbers the old Q5 to Q4 and adds the missing "然后接上 DC 12V 适配器" step in the troubleshooting list.
  3. Adds a :::note clarifying the power supply design (DC 12V / PoE vs. Type-C).

- Remove the obsolete Q4 about USB PD power negotiation via the on-board
  Type-C port; ROCK 5T is powered by a DC 12V adapter (or PoE), the
  Type-C port is only for OTG/data/Maskrom and does not power the board.
- Renumber the old Q5 (USB-C + Maskrom check) to Q4 and add the missing
  step to connect the DC 12V adapter before expecting the green LED.
- Add a note clarifying the DC 12V / Type-C power relationship.
