Quick start guide

The canonical example of RTE usage is hooking it to some hardware for SPI flashing, power control and serial logs gathering. This document describes the common preparation of RTE without listed functions.


  • RTE board (this document is based on v1.1.0)
  • Micro-USB 5V 2.5A power supply
  • Orange Pi
  • SD card
  • Ethernet cable
  • USB-UART converter with 3 wire cables
  • Ubuntu (based on 22.04)

Preparation of RTE

  1. Download the latest version of the RTE image from the meta-rte repository.
  2. Flash the SD card using bmaptool or balenaEtcher.

    1. to do this by balenaEtcher go to the producer site and follow his procedure on how to download and flash an SD card.
    2. to do this by bmaptool reproduce the following steps:

      1. install bmaptool by opening the terminal and typing the following command:

        sudo apt install bmap-tools
      2. create the bmap by typing the following command:

        bmaptool create /path/to/your/image > /path/where/you/want/bmap/file/saved/bmapfilename.bmap
      3. flash image to the SD card by typing the following command:

        sudo bmaptool copy --bmap ~/path/where/your/bmap/file/is/located /path/where/your/image/is/located /path/to/memory/device
  3. Insert Orange Pi into RTE.

  4. Insert SD card into Orange Pi.
  5. Connect the ethernet cable to Orange Pi.
  6. Plug the USB-UART converter into your computer and connect its pins with RTE J2 Header. (you may need a USB extension cable)

    UART Converter RTE J2 Header
    TXD RX
    RXD TX
  7. Open the serial connection with RTE from your PC using a previously connected USB-UART converter by executing the following command:

    sudo minicom -D /dev/ttyUSB<x>

    Substitute <x> with the device number corresponding to your USB-UART Converter for example /dev/ttyUSB0. The dmesg command allows to identify the latest connected devices.

  8. Plug the power supply into the RTE J17 Micro-USB slot.

  9. Login into the device by using the default credentials:
    • Login: root
    • Password: meta-rte
