Hi,
        I am try to boot the 2.6.23-rc3 kernel to my custom board  
based on
8641D Processor. After uncompressing the kernel it was hang. I got the
following messages.

   Uncompressing Kernel Image ... OK
   Booting using flat device tree at 0x600000.

       Then i tried to debug with GDB. In my source path i given  
the command
${CROSS_COMPILE}gdb vmlinux, I got GDB Prompt after i tried to set the
breakpoint at start_kernel. I got follwing messages

gdb) b start_kernel
Cannot access memory at address 0xc02b44ec

how are you connecting gdb to the board?

do you have a JTAG debugger connected to the board?
