Set a breakpoint at the end of the decompression stage of what you call
the uncompressed portion of the zImage.elf file, then single step your
way past the transition to virtual mappings, reload your symbols from
the vmlinux file and you're set to go.  Tedious but that forces you to
think about each step much harder rather than to indulge in trial and
error.

I am using a Xilinx ML403 board with the Parallel IV JTAG cable.  I have 
been able to use XMD and the Insight front end for GDB to debug both 
U-Boot and the uncompressed portion of the zImage.elf file.  However, I 
cannot set breakpoints in kernel code.  Can XMD  and the Parallel IV 
JTAG cable be used to debug kernel code?  How do you do that?

Thanks,
Frank
