Embedded Linux
 

I'm new to this site. What's the smallest Linux kernel size? Is it possible to use on ARM M4?

Hi, and welcome!

From what I can find, it seems to be possible to run Linux on an M4, but as it doesn't have a MMU, you need to run a version of Linux written for this, namely μClinux.

Some resources:
