Smallest OS for Raspberry Pi

Fri Mar 28, 2014 12:52 pm

Please advise which is the smallest available OS for the Raspberry Pi, preferably with no GUI components as I do all my own and I need as much space for media as possible on my 8GB SDHC.

Anything smaller than TinyCoreLinux? It extracts out to 17-ish MB. I need it 16MB or less.

Ya just something that fits on 15.9MB. If possible just a build that can SSH.

Hi
I can provide you with an image 12MB in size if you're interested. It's minimalistic but has SSH, FTP and most other core utils one essentially needs.

Original question didn't specify which OS, most answers assume a cut-down Linux distribution.

My first response would be a question - what do you need it to do? And then how much are you prepared to do yourself?
If you don't need multi-tasking, standard packages, etc. you could build something very simple on some of the bare metal examples. I have made my own simple modular OS from scratch with writable FAT file system, keyboard, serial comms and command shell in around 200k but that's taken 2 years on and (mostly) off ;) Others have similar hobby OS's.

Otherwise you may find the right set of functionality in one of the distros mentioned above, or create your own. I'm not sure how much effort that would be relative to a bare metal approach, again depends on what you need.
