Hi,
1) First, please note that I am only having this issue from
a linux terminal and not windows terminal. My target board
is connected to a Windows host running a gdb stub.
(Actually a Xilinx application called XMDStub).
I connect to the target using remote tcp (my gdb on a host
communicates with the gdb stub). I am trying to get this to
work from a linux host running gdb and I am having
problems. I can connect to my target and run the
application but I cannot set breakpoints or step through
the code. I can put one breakpoint and I can reach there
but when I try to continue I get this message
Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000000 in ?? ()
I would like to know why this is happening. Also I noticed
that when I connect to my target (using Linux) with the
command "target remote xxx:port executable.elf" command, I
get this reply back
Remote debugging using xxx:port executable.elf
0x00000000 in ?? ()
>From a windows host running gdb, doing the same thing shows
a non zero address. What is this address??
2) I have a question regarding cross-compilers and cross
debuggers. Does it matter for the debugger if my
application was compiled from windows for a ppc target
(cygwin-ppc cross compiler) or from linux for a ppc target
(linux-ppc cross compiler).
Additional Information
--------------------
1) - My windows host runs a Xilinx supplied version of
Insight/gdb
- My Linux host runs the standard Insight/gdb downloaded
from Redhat site
- The target is connect to a Windows machine running a
Xilinx supplied gdb stub called XMD Stub
Is Its possible that the Xilinx supplied Insight has some
configuration settings that I should use for my Linux
version of insight.
Thanks,
