[U-Boot-Users] Uboot Netconsole support

Thanks for the reply Mr.Wolfgang.

Correct me if I am wrong.

Our requirement is such that uboot should print (debug) messages while
it is coming up. I do think that the present uboot is doing that but our
requirement is that it must do so on Ethernet console instead of Serial
port. Finally the CLI must start on the Ethernet.

With Best Regards,

As you already found out it does not contain this feature.

No, ther eare no patches. There is a current  version  (top  of  CVS)
which includes this so no patches are needed.

What exactly do you mean "before the IP comes up"?

You have to explain what you want to do in such a  way  that  we  can
understand it.

The page reads: "Crunched and crypted init procedure to protect linux
server." This is something else  -  a  completely  different  project
unrelated to "Das U-Boot".

These are two completely different projects. If you actually  READ  a
bit on the web pages you jump to you might learn the difference.

The last officially released version of U-Boot can be  found  on  the
web  page  at  SF:  it's U-Boot-1.1.1; the current development verion
(1.1.2) is available on the CVS server at SF.

And all of this is information is available by reading a bit  on  the
SF web page and in the mailing list archives.
