<DIV><SPAN class=625292512-25082006><FONT face=Arial size=2>
We are working on MPC 8540, Linux kernel version is 2.6.10 from Montavista. The
bootloader used in Uboot and currently it loads the uImage at physical memory
address 0x0 and transfers control to it. We want to load the kernel at a
different address say 0x8000 and for this we made the following
changes.</FONT></SPAN></DIV>

<DIV><SPAN class=625292512-25082006><FONT face=Arial size=2>1) Altered the
Makefile to linked the kernel at virtual address 0xc0008000 ( the default was
0xc000:0000)</FONT></SPAN></DIV>
<DIV><SPAN class=625292512-25082006><FONT face=Arial size=2>2) Modified Uboot to
load kernel at 0x8000 instead of 0x0</FONT></SPAN></DIV>

<P><SPAN class=625292512-25082006>The kernel space still starts from
0xc000:0000</SPAN></P></FONT></SPAN></DIV>

<DIV><SPAN class=625292512-25082006><FONT face=Arial size=2>When we transferred
control to the kernel (loaded at 0x8000) we found that the execution proceeds
only till the mapping and invalidation on TLBs. We do not know where the
control goes after this as the further instructions does not seems to get
executed. Currently we do not have the provision to connect a debugger and hence
we are unable to make out what is happening.</FONT></SPAN></DIV>
