Mini2440 - Help with Ethernet Connection on Uboot

CRASHOVERRIDE

2012-06-14 19:12:19

Hi all,

I can boot my board Mini2440 by SDCard, but i have a problem with the
ethernet connection, neither the pc or the board detects the connection
through the ethernet cable. If anyone can help me with this problem, i
would be appreciated.

This is my boot of kernel on uboot:

Linux version 2.6.32-rc8

From my failing memory that kernel had problems.  Have a look on this site
http://billforums.station51.net
maybe there are some comments there

Why such an old kernel?

However, what have you got in /etc/network/interfaces ?

Shouldn't there be a eth0 ?

Hi davef,

Thank you for your reply, i'm noob in linux and i have some problem with
the commands of console, because i don't know many of it.

Welcome to Buildroot

But the problem still the same, the eth0 don't start with the boot. Today i
had some progress, and i was able to ping my pc through board and the other
way the board to pc.
I configure the eth0 in board through the commands "ifconfig eth0
192.168.1.2 netmask 255.255.255.0 up", follow by "route add -host
192.168.1.1 eth0".

This way everything works, but now i need this configuration to start with
boot of the board. Can you help me with this??

Sorry for my english.

Be aware that there are many patches to apply to the mainline kernels to
get them to work on the mini2440.  At least that was the situation 6 months
ago.

What have you got in your /etc/network/interfaces file?

Is buildroot using udev?

The will be somewhere that sets up your ethernet stuff.  A udev rule,
/etc/init.d/rcS or other places in /etc there will be some start-up script
for the DM9000.

Happy searching.

Hi davef,

Thank for your help, through the file rcS in "/etc/init.d", i solve the
problem, no the way i wanted, because the ip get fixed in the board, but it
works and that is what matters.

I put this lines in the end of the file:

"ifconfig eth0 192.168.1.2 netmask 255.255.255.0 up"
"route add -host 192.168.1.1 eth0"

And now when i boot the board, it already configures the network.

Regards,
CRASHOVERRIDE
