Re: [Ltib] Ltib - network missing

[Li Yuan-Lung]

Dear Srinivas,

I am confused about the mechanism. In kernel 2.6.27 the MAC address was in the EEPROM and the address info will be got after platform initialization. In kernel 2.6.34 the MAC address was just took from the boot parameter but not the EEPROM, why?

It doesn't make sense for the MAC address storage just keeping in the boot parameter. Is there any consideration?

Is there any possibility to change back to the previous method?

Hi Henry,

                The kernel needs to be passed the MAC address from the uboot in 2.6.34.

like :

setenv bootargs console=ttyS0,115200n8 root=/dev/mtdblock3 ethaddr="your mac address"

Dear Kevin,

I am still using the LPC3250 board.

This Monday I just found that the kernel 2.6.34 was released, then I tried it.

Unfortunately the network is not work. In the Ltib config I change the kernel version back to the 2.6.27.8. The net work is work well.

Could you please help me to check what's wrong?

The attachment is bootup logs by each kernel.

Note that the they are running on the same board(I just have one board), but the kernel 2.6.34 can not find eth0.

 

Thank you in advance.

 

Henry
