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

If the porting is possible can anyone No, proting is still possible, it involves just one additional step: fixong your boot loader to provide a different memory map. > help me out where to change the memory mapping of Linux for MPC8260?

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.
