Hi windstorm,
Have you correct the error, you get when generating the ace file?? I'm
trying to build the linux system for the XUPV2P board, and I have the same
error:
Using GenACE option file : xupGenace.opt
Error: Executable zImage.elf does not contain start address..
As you and Xilinx said in the answer
(http://www.xilinx.com/support/answers/23192.htm) my genace.tcl file is
patched, and it uses de powerPC objdump.
I have tryed to use the ppc_4xx-objdump cross tool of ELDK instead of the
powerpc-eabi-objdump that is used in the genace.tcl file, and the result was
an error:

but the Error:executable zImage.elf does not contain start address.. didn't
appear. And the compiler assign the address 0x00400000...
This error is the same, that xmd told me if I try to download directly the
linux kernel to the board, maybe there is any relation...
I don't know what is happening...
Any info or help???
