[U-Boot-Users] adding tcp
We use u-boot 0.4.0 and we need to add tcp protocol. Is it possible?
thanks

Yes, and it's trivial. It's a two-step procedure. In the first step you will start standard U-Boot, and in the second step you will boot an operating system (Linux recommended).
In other words: don't. U-Boot is a boot loader, and you don't need nor want a full TCP stack here.
BTW: I strongly recommend to update - version 0.4.0 is _very_ old.

No. We need to embed tcp in u-boot.

unfortunately we need to provide some features (involving tcp) before linux was boot. Is it so difficult to embed tcp in u-boot?

We were asked to use 0.4.0. Obviously I prefer to use a more recent version but unfortunately we can't.
thanks
Dear Mastupristi?

No, you don't. Forget it. A full-blown TCP/IP stack requires much more services than avialable in U-Boot. Please repeat after me: U-Boot is just a boot loader, it is NOT an operating system.

Then boot a minimized Linux kernel first. Or, if this is not allowed by your Powers That Be, then boot a NetBSD image for this task ;-)

Short answer: yes.

Then do yourself a favour and reject this job. All your work would be wasted. It makes NO, absolutely NO sense to base current work (especially work that is intended to add major extensions) on old code that has been obsoleted more than a year ago.
