RE: GDB, xilinx ml50x

[Brian Hill <brian.hill@xilinx.com>]

Stuart,
I've successfully used GDB with our GIT Linux kernel.  This was with a
root file system I'd created using buildroot
(http://buildroot.uclibc.org/).  Buildroot includes the option to build
a gdbserver ("man gdbserver" for details of how to use this application)
which can be run on the target. The XMD GDB server is most definitely
_not_ suited to debugging a Linux process.  I've used the XMD GDB server
to look at global kernel data structures and the like -- and that is
about all it could be used for.
