Ethernet on micro2440

2011-01-12 05:30:20

I successfully compiled and run linux 2.6.32 on the micro 2440 SDK, but I
could not bring the ethernet up

This is what happen on the console:
# ifconfig  
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0

eth0: dm9000e at c48a8300,c48ac304 IRQ 51 MAC: 08:90:90:90:90:90 (chip)
# 

The LEDS at the ethernet port are always off, even if I connected the board
to the ethernet hub. I can not ping to the hub. 

# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
ping: sendto: Network is unreachable
# 

How can I bring up the internet interface? What options do I have to enable
in the kernel?

Thanks

Try post boot log. Seems interface is not up or has different name but eth0
should work. ifup gives you error so ping can't work.

Thank for your quick reply

ifconfig up eth0 didn't work, either.

There are some problems with flash partitions. Your rootfs is mounted from
flash or nfs or sd card?

Anyway as Tobias stated check your cables ;)

good luck,

marek

The rootfs is in SDCARD.
The hub and cable work OK. I checked it by connecting my PC to the hub with
this cable

Maybe something wrong with the network configuration.

Have such a issue when test emdebian (there was eth1 interface). Check ifup
eth1. No other ideas. Sorry.

do you have udev on your system?

i think udev renamed eth0 to eth1.
just have a look in 
/etc/udev/rules.d/70-persistent-net.rules
and delete everything in there and make a reboot

Finally I got i work.

I have to add the following lines to /etc/network/interfaces

auto eth0
iface eth0 inet static
address 192.168.1.230
netmask 255.255.255.0
broadcast 192.168.1.255

Now:

It is strange that I am the only one who had this problem. To get the
micro2440 work I has to do a lot of manual configuration.

Bao,

Would you be willing to share what all manual steps were required to get
micro2440 to work ? Maybe if you have some notes of what all needs to be
done. We are moving out of the SDK to the micro2440 standalone.
