Hi,
My image boots up to the following serial output message,

Ram5
Ram6
Copying LinuxBIOS to ram.
Jumping to LinuxBIOS.


It says that it is jumpimg to LinuxBIOS, that means it has copied the
images to RAM. So next step is to CALL(harwaremain). It is not jumping
in to hardwaremain function.

>From the linuxbios.map I found that address of hardwaremain function is
00000904 T hardwaremain

I have checked my DDR SDRAM register programming and initialization
progams with specification. It looks ok to me. If you want I can send it
for reference.

I want to verify that following option that I am using are correct are
not,

Some configuration I am using are as follow,

I am not currently enabling MTRR. Currently I am look with the
performance. 

I am not supporting SMP now.

I also verified some of the DDR SDRAM register by read it back.

I am using 256 KB Flash ROM and 256 MB RAM. While burning the Flash I am
burning the 65 KB linuxbios.strip file on FLASH ROM.

I have attached the makefile.settings along with this mail.


Can any one help me in resolving the problem ;-(

-Siva
