Not enough space on RevPi core 3 with Codesys

Hello,
We started a new Codesys project on RevPi core3 (4GB) version- because only this was avaliable on the market.
We installed Codesys Runtime, PHP, MySql and we run out of Memory and we didnt even started the programing...
Is there any "light" version of the OS ? What are the biggest packages that we can remove in order to have more space ?

The OS itself consume around 3,1 -3,5GB and there is literaly no space for anything. Even on stand by the machine fill in the memory to 100 % and everything stops working.

Hi Ivan,

if you don't the graphical environment you can free some space by uninstalling packages:

sudo apt purge libgl1-mesa-dri nodejs teamviewer-revpi pypy realvnc-vnc-server chromium mesa-va-drivers libgtk-3-common adwaita-icon-theme gnome-icon-theme
sudo apt autoremove --purge

There are some additional, larger packages which can be uninstalled if you don't need them:

sudo apt purge nodejs teamviewer-revpi vnc-server
sudo apt autoremove --purge

In total this should free approx. 1 GB of disk space.

Nicolai

Thank you for the support.
Now we are at about 77%

Hello,
After some time of operation we again have around 100mB of free space.
Is there any other big package that we can romove without damaging the system?
