[U-Boot-Users] About Network Console Protocol and nc/ncb

[Frederic Kwiatkowski]

Hi all


I'm wondering how to use te Network Console Protocol. I've read the
README.NetConsole file and discoverd it, but does this feature is
available on every boards-configs, such as the at91 one?

I've tried to set the env variable like this:
setenv nc 'setenv stdout nc;setenv stdin nc'
setenv ncip 192.168.0.66 (wich is the board's IP)
run nc

and run the following script on my Linux Computer:
#! /bin/bash

[ $# = 1 ] || { echo "Usage: $0 target_ip" >&2 ; exit 1 ; }
TARGET_IP=$1

stty icanon echo intr ^T
./ncb &
nc -u ${TARGET_IP} 6666
stty icanon echo intr ^C
kill 0


but when i try to use ./ncip.sh 192.168.0.66, nothings happen
So i thoutgh the ncip have to be the one of my desktop computer, but
nothing better


Does anyone have already use this feature?


With regards

Frederic

If you enable it, it should work. But only few  boards  actually  use
this feature in their default configuration.

Run a sniffer (ethereal) on your network and check  if  you  see  any
packets  at  all.  You  *did*  switch  the stdin / stdout channels in
U-Boot, didn't you?

Yes, it is being used actively on a couple of boards, some of them in
production with high volumes.

Is there any #define to enable it or must I modify some sources file to do this?

if setenv nc 'setenv stdout nc;setenv stdin nc have succed, with run
nc, it is switched
But, i've seen with ethereal that no packets where transmited through
my eth interface
It might be the first step to solve this problem

#define CONFIG_NETCONSOLE in your board config file.

Yes. [And you don't see any more output on the U-Boot console, right?]

Indeed.

I'll try this, and debugging my errors
                -Map u-boot.map -o u-boot

/home/smb/uc-dev/frk/u-boot_051108/drivers/netconsole.c:116: undefined

thanks for all, i hope i should solve my problems now
