    *Booting from onboard eMMC

    NOTE: Booting from the onboard eMMC is only available for models with eMMC.

    Requirement:

    • 1 x Type-C® cable with data transfer function

    • 1 x Power supply

    • 1 x Monitor

    • 1 x Keyboard and Mouse set

    Setting Up:

    1. Make sure there is no jumper on the Recovery header.

    2. Connect the Tinker Edge R to a PC using a Type-C® cable.

    3. Connect the power adapter to the Tinker Edge R.

    4. Download the TinkerOS image from the Tinker Board website (https://tinker-board.asus.com/download-list.html?product=tinker-edge-r) and burn it into the Tinker Board using a third-party ISO software, such as balenaEtcher.

    5. After the TinkerOS image is successfully burned, disconnect all cables from the Tinker Board.

    6. Connect the power supply, keyboard, mouse, and monitor to your Tinker Board to boot up.

 

2. Hardware Guide

2.1 GPIO Application note

Due to hardware design limitations of certain pins, some designs incorporate level shifters, so there are a few things to keep in mind when using them.

  • The location of pins with level shifter:
  • Pins number: 7, 12, 13, 15, 16, 18, 19, 21, 22, 23, 24, 26, 29, 31, 35, 38, 40 image

Precautions for use:

If used as a GPI

  • A pull-up/ pull-down resistor is needed to automatically restore the default state.
  • If default status=1, need to add an external pull-up resistor and must be less than 1.65KΩ.
  • If default status=0, it is recommended to use 100KΩ resistor to pull-down.
  • This pin can no longer be set to GPO by the software (unless the external resistor design is modified!).

Requirements in the datasheet for input:

2.2 FAN control

Control GPIO4_D6 the high speed or low speed by software

  1. High speed setting on FAN_SPD_CTRL
sudo echo "158" > /sys/class/gpio/export
sudo echo "out" > /sys/class/gpio/gpio158/direction
sudo echo "1" /sys/class/gpio/gpio154/value
  1. Low speed setting on FAN_SPD_CTRL
sudo echo "158" > /sys/class/gpio/export
sudo echo "out" > /sys/class/gpio/gpio158/direction
sudo echo "0" > /sys/class/gpio/gpio158/value
