Warning

The dd command will completely erase your MicroSD device so make sure you are targeting the correct one.

Unzip and flash the image:

unzip ethonarm_21.03.00.img.zip
sudo dd bs=1M if=ethonarm_21.03.00.img of=/dev/mmcblk0 conv=fdatasync status=progress

Insert MicroSD

Warning

The image will wipe out your USB SSD disk, so be careful if you already have data on it.

Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port which corresponds to USB 3).

Power on

The Ubuntu OS will boot up in less than one minute and will start to perform the necessary tasks to turn the device into a full Ethereum node.

Warning

You need to wait for about 10-15 minutes to allow the script to install and configure all the software.

Log in

Once the device is available, You can log in through SSH or using the console (if you have a monitor and keyboard attached) using the ethereum account:

User: ethereum
Password: ethereum

Through SSH:

ssh ethereum@your_raspberrypi_IP

Tip

If you don’t have a monitor with a keyboard you can get your Raspberry Pi IP address by looking into your router or using some kind of network tool such as fping or nmap. For instance (assuming you are in the 192.168.1.0 network)).

In your Linux Desktop / Laptop, run:

Using Nmap

sudo apt-get install nmap
nmap -sP 192.168.1.0/24

Using Fping

sudo apt-get install fping
fping -a -g 192.168.1.0/24

Note

You will be prompted to change the password on first login, so you will need to log in twice.
