IP-Config: Failed to open eth0

[kabbin]

Hello
    I use arm-linux-gcc 3.4.1 to build kernel 2.6.10 for omap2420h4 
but I cannot mount NFS

I got the following message:

Dear all: 
  I cannot boot from NFS. Could anyone help me please?  My board is omap2420h4,  kernel 2.6.10  


Does following means that the network driver configuration is wrong?
Why Invalid ethernet MAC address ?  I have setenv ethaddr already.

I got :

Did you read that hint? ifconfig (8) lives on your NFS root you so you
have serious problem ;-) You can either use initrd as workaround 
or preferably set MAC address corectly. Assuming you are using U-boot:

You can also look at U-Boot source code:
board/voiceblue/eeprom.c

Debug Output

[Abot Botbot]

Hello all,


    I'm trying to edit the RF6 refference framework application to suit my 
purposes. At the moment I want to get a feel for how many samples go through 
their filter with each message from the GPP. My algorithm works on a sample 
by sample basis, so I'm guessing I want to do my loop multiple times per 
message from the GPP. My questions is, how can I output basic debug material 
to the console? Can I just throw printf statements in any place in the code 
and see the output in the console? I see statments like "UTL_logDebug( 
"Application started." );" etc, where does that output end up?

Thanks,
Andy

Thanks for your help. 
I have read the post, as Wolfgang Denk said, It's a bug in the Linux ethernet driver. 

http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2004-July/023579.html

But Could somebody tell me how to fix to bug? I cannot find a answer in the mail list.

By the way, as my board is omap2420h4, and I could not find the file:
//uboot/board/omap2420h4/eeprom.c 

Best regards.

Re: IP-Config: Failed to open eth0

Hello
  Could you tell me how can I set the MAC address ?
What does it mean to use ifconfig ?  
(I have set ethaddr already, so tftp work fine)
Thanks. Best regards.
