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.

I used to be indecisive, now I'm not sure.

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

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.

Instead of TCP, might netconsole be a suitable substitute?
U-Boot has it.
