   Question:: I am using the cross-gdb from ELDK together with the BDI
    JTAG hardware debugger from Abatron to debug my e500 based system.
    When I try to attach to the BDI from within gdb, I get an error
    message like this:
    <verbatim>
$ ppc_85xxDP-gdb u-boot

.......

   Answer:: If you are using at least BDI firmware v1.09 then most probably
    you forgot to include the following directive in the BDI config file:
    <verbatim>
[TARGET]
REGLIST     E500        ;send registers in E500 sequence to GDB
    </verbatim>
    Also be sure that the gdb really thinks that it debugs an e500
    core:
    <verbatim>
(gdb) show architecture 
The target architecture is set automatically (currently powerpc:e500)
(gdb)
    </verbatim>
    If this is not the case, then fix this problem first.  It might
    just be that you are not using the right cross debugger in the
    first place.
