Hi all,
Thanks everyone for the time. It's done and I have it working.
I have another question regarding MAC address in Linux. I had ported
U-boot onto our customized board (MPC8280 based). It is working fine. I am
also able to boot a Linux Kernel. The Kernel version is Linux-2.4.20 .
We set the MAC address for the board in U-boot as 00:FD:11:01:01:01. But
when the Linux Kernel boots it takes the MAC as 00:FD:81:01:01:01.
I have confirmed that the U-boot passes the MAC address properly to the
Linux Kernel properly. Can anyone guide me to where to look out for the
issue stated above in the Linux code?
Thanks everyone for the time.
With Regards,
C.R.Srivatsan

Check if there're some hack in fcc_enet.c driver code, regarding the MAC=20
address setup.

Dear all,
I am having a MPC8260 based board with the following memory map.
Device Start address End address
EPROM 0x00000000 0x03FFFFFF
SDRAM 0x04000000 0x13FFFFFF
I have a doubt regarding Linux Port onto this board. I have read on the web
that Linux usually expects the SDRAM at 0x0, is it that the porting of linux
onto this board is totally impossible? If the porting is possible can anyone
help me out where to change the memory mapping of Linux for MPC8260?
Thanking you all for your time. Kindly help me out to solve this issue.
With Regards,
C.R.Srivatsan

No, proting is still possible, it involves just one additional step:
fixong your boot loader to provide a different memory map.

In your boot loader.
