Blank screen

Voine

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,

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:

install flashtool
download FIP: https://luxonisos.fra1.digitaloceanspaces.com/release/recovery/fip-dm3370-r5m2e5-1.8.1.bin
download OS: https://luxonisos.fra1.digitaloceanspaces.com/build/1.14-rae+6263cb8c60f2cbfc80cc523f2b37581eb38139aa/luxonisos-1.14-rae.zip
turn off rae
press pin hole button
turn on rae
flashtool flashall fip-dm3370-r5m2e5-1.8.1.bin data.img boot.img system.img syshash.img

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,

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

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.

It's the same one.
