Hi, it depends on what programs you have running. I remember having a headless Jessie server running ssh with just 55MB memory usage a while ago. Also people have been using custom Debian rootfs images with the LicheePi Zero board that has 64MB of RAM.
I don't know about the storage requirements. hh h: > Hi, > > What is the minimal RAM and Flash size to install Stretch armhf image, > of cause there is no desktop, it is an ARM embedded system?
