[microblaze-uclinux] microblaze clock freq and ethernet

[anand_12 <anand_12@xxxxxxxxxxxx>]

hi all

 I am running uClinux on the memec spartan 2 E board(microblaze softcore).

 Currently the clock frequency of MicroBlaze I am using is 66 MHz which is necessary for 100 Mbps ethernet(according to MicroBlaze design document,actually it says >65 <100 Mhz)

I reduced the clock freq to 50 Mhz and when I compile the kernel and execute it on board,it boots up properly but the ethernet does not seem to work...i am not able to ping either to the board or from the board to any other host on the network...

i am not very particular of a 100 Mbps ethernet connection...even 10 Mbps would do(for this case the minimum clock freq is 6.5 Mhz,as per the design doc)

what i want to know is :

-> should any changes be made to the kernel configuration /header files/etc ?..what i have done now just change the CPU clock frequency to 50 Mhz.

Thanks in advance for any help

cheers
