difference between the two?

The operating system itself is basicaly the same. "Embedded linux" usualy means a toolchain (compilers, libraries etc.) and stripped down applications such that the root file system have a small footprint. Sometimes there is some tools that help to build the root file system.

hi, I am a new to this field but you can say that embedded Linux is a customized version of Linux that works over embedded system.

Hi,

embedded Linux can run on microprocessors and microcontrollers without having to use a MMU (Memory Management Unit). "Regular" Linux followed in the latest version and can do that now as well. Myself coming from small embedded microcontrollers the difference between the two OSs is that one is incredibly huge and the other one outragesly huge, you figure out which is which. You can run a reasonable system using E-Linux with less than 10 MBytes of memory, where as memory better be mostly RAM, while Linux is not really happy without having double digits MBytes of RAM.

Your are mixing up Linux and uClinux. Embedded Linux != ucLinux.

I've read somewhere that one can have linux runing out of as low as 2MB of flash and 4MB of RAM. I have no idea if such a system would be very useful though. I how much smaller is uCLinux' footprint but I doubt it is significantly smaller.

Linux is sure bloated these days. I remember (ack, 12-13 years ago) running 0.14 on my 386SX with 2 MB of RAM. It ram out of 1MB, but the upgrade was worthwhile ;)

You are right,

sorry for the confusion. I was talking about uCLinux :-|

Who, and about what? See sig. below

What confusion? Did you say anything? See sig. below.
