Rpi 4B 2 Gb not booting from image
As promised:

start4.elf: is not compatible
This board requires newer software.

-> Openplotter does not support the latest firmware and thus new rpi's from the shelf.
Could someone with a failing RPi4 2GB join the test round for the new OpenPlotter 3?

I will post an alpha version ASAP here:
Sure, easy enough to burn an sd card and plop it in Smile
I have the same problem, but with a 4GB

(Pi 4 Model B 4GB, purchased this week from the Pihut)

I get the same message as RovingGecko ...

start4.elf: is not compatible

OpenPlotter 3 Alpha released:

Please report here about the issue with RPi4 2GB
Openplotter 3 alpha - 32-bit boots just fine on rpi 4 2Gb that did not boot openplotter 2.
After boot I get the normal desktop.

Will do similar test with 64-bit and revert.
Openplotter 3 alpha - 64-bit boots just fine on rpi 4 2 GB as well.

-> new images support the latest rpi firmware.
We just installed OP 3 64 bit on an pi 4 with 2gb.
Works like a charme. OpenCPN Flat installation worked also fine.

As total noobs we are assuming, that network installation for headless mode isn't realized in the current version. Right?

Thanks for the fast new image

To Install OpenPlotter on any computer running a Linux Debian derivative system (Raspberry PI OS, Ubuntu, Linux Mint…) you have to install the dependencies.

Open a terminal and type:

sudo apt update
sudo apt install python3-wxgtk4.0 python3-ujson python3-pyudev whois vlc
Now you have to install the main app openplotter-setting from the .deb file you can download from the Advanced section in downloading chapter.

After downloading the .deb file, you can install it by double click or typing this in a terminal:

sudo dpkg -i openplotter-settings_x.x.x-stable.deb
Every time OpenPlotter needs to perform an action that requires administrator permission, it will ask for the password. To avoid having to continuously enter your administrator password you can add your user to the sudoers list. Do this only if you know what you are doing:

sudo visudo
Add this line to the end of the document and save:


Hi ! thanks for your advise.
But still in troubles here with my RPI 4.B. I have downloaded the .deb of the advanced downloading part. But the command you wrote above does not work, and nothing happen when I double clic on it.
