[U-Boot] Problem with NetConsole

[U-Boot] Problem with NetConsole

[alex889]

Hi,
I'm trying to add the NetConsole to my project.
I've set all the related environment variables

when i start UBoot and then type "run nc" i see that i receive the data i'm
sending from remote PC,
but if i call "run nc" from within the UBoot, using run_command("run nc",
1);,  i don't receive that data.

Am i doing something wrong?

Thanks,
Alex

Yes, that much is sure, as it doesn't work for you.

Since you don't provide any deyails of your code changes (like a
patch against top-of-tree in mainline) we can only guess. My guess
is: You are missing a semicolon in line 42.

OK
So let me rephrase myself
My aim is to open the NetConsole for input (stdin=nc)only if the user
pressed on a specific button.
How should the code that opens the NetConsole look like, after i discovered
the button was pressed?

Thanks,
Alex

setenv("stdin", "nc");

Of course, you must make sure to run this only after device
intialization.

There are no data that cannot be plotted on a straight  line  if  the
axis are chosen correctly.

Thanks Wolfgang !
that helped,
the last question i have is: I want the NetConsole to listen for incoming
messages for 2 sec,
I've tried using NetSetTimeout, but it seems to not work
