• RAE

  • Blank screen

I performed a soft reset by SSHing into the robot and executing the following commands:

rm -rf /data
rm -rf /var
rm -rf /etc

post-reset, the RAE is now cannot boot, displaying only a blank screen while powered on. Is there any solution for this?

    Hi Voine
    Can you ssh to it via USB connected to the side port?
    You should be able to reset it using the reset button on the bottom of the device.

    Thanks,
    Jaka

      No, I am unable to access SSH through USB. Additionally, I attempted a reset by pressing the button, but it had no effect.

      Hi @Voine
      The steps would be:

      flashtool is tested on Linux machines (Ubuntu). You may need to set some udev rules first:

      echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="0b39", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/80-keembay.rules
echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="da00", GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/80-keembay.rules
sudo udevadm control --reload-rules && sudo udevadm trigger
pip3 install --user .
flashtool --help

      Thanks,
      Jaka

        Hi Jaka,

        I got this output after following your step:

        Here the detailed step for what I did:

        1. I install the flash tool from (https://docs.google.com/document/d/1r3en4EqgDG3hum8o5yS1DJ5vSCb6aNqyA38tIM8723U/edit)

        by running:
        **python3 -m pip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ flashtool
        **
        2. I Downloaded FIP and OS files and extract it in my Downloads folder.

        3. Set udev rules by running the command you gave me:
        echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="0b39", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/80-keembay.rules echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="da00", GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/80-keembay.rules sudo udevadm control --reload-rules && sudo udevadm trigger pip3 install --user . flashtool --help

        4. Turn off my RAE and then plug it to my computer with USB.

        5. Resetting by pressing the pin hole button

        6. Turn on RAE

        7. run command:
        flashtool flashall fip-dm3370-r5m2e5-1.8.1.bin data.img boot.img system.img syshash.img

        Is there a mistep?
        My system is Ubuntu 22.04.3 LTS

            Oh, right. You have to put rae in recovery mode. The steps are fine, but at the end:

            • un-plug/re-plug the battery - just making sure there is not power to the SoM.
            • press and hold boot button
            • press and hold power button
            • plug in the usb cable
            • release both buttons

            Now run the command. If you are experiencing pcie issues, you can pass the -d usb flag to flashtool command.

            Thanks,
            Jaka

                • un-plug/re-plug the battery - just making sure there is not power to the SoM.

                • press and hold boot button

                • press and hold power button

                • plug in the usb cable

                • release both buttons


                  To clarify, this step is to put the rae in the recovery mode right?
                  Is the step involving unplugging and replugging the battery optional? I'm concerned it might require opening up the rae, which I want to avoid if not necessary.
                  Is the boot button referred is the same as the reset button, or is there a different boot button inside?

                    I believe so.

                    Voine Is the boot button referred is the same as the reset button, or is there a different boot button inside?

                    It's the same one.
