I am using U-Boot loader 1.1.4 and I am using IntegratorCP ARM Boards. I am facing the problems while booting, I debugged my Kernel with Low Level Debugging.I think My problem is in 'Call_Kernel' Function in head.S and I am using kernel 2.6.16.
## Checking Image at 00007fc0 ...

410FB760:00000113:00050078 ^^^^^^^^^^^^_________________________Processor ID seeems to be OK ^^^^^^^^^^^_________________Architecture ID is also ok ^^^^^^^^^^^________What is Control Register? Is this related with Params? If it is Param my param is wrong here.
0013AB68-0037EF68>00008000 ^^^^^^^^^^^_______Kernel Execution Address is Ok
This is my print statement in head.S in 'call_kernel'.
:00000000%00000000@00000040*00008000 ^^^^^^^^^^^__________________________r0 is 0 Perfect ^^^^^^^^^^^^________________Here the machine ID is wrong. I want to get as 0x113. But I am getting 0. ^^^^^^^^^^^^______HOw to check the ATAG ID. Is it related with Params? ^^^^^^^^_ Kernel Execution ID seems to be Ok.
Please anybody help me. I am new to u-boot and kernel.
