[openrisc] Question about or1ksim with gdb

[SUNGYON@aaww.com]

Chris Ziomkowski and many forerunner!
Nowasdays i sended many Questions here and i got trouble-shooting answers.
I finished the compilation of "mini-mad" program with or32-rtems-..... thanks to
some of you.
I want to run this code and see the printf message, but even hello.exe(in
rtems4.5) failed.

I see the README.or1k which Chris wrote in or1k/rtems/, the link of or1ksim &
gdb5.0.
There, it seems that he is successful to run "hello.exe" with or1ksim & gdb
interface.
But in my case, gdb does not be connected to the or1ksim (server).
The jtag port is opened for sure, and gdb find the port, but gdb cannot finish
the jtag connection.

I edited memory section of sim.cfg according to configuation file used by
'or32-rtems-ld'
I try the standalone simulation of or1ksim. it resulted in segmentation fault.
If i escape the connection peding, and jump to highly probable start address(in
gdb), it also fails.
I think the critical problem is insufficient jtag connection.

If i success in the hello.exe of rtems4.5, i think all preliminary work for my
minimad analysis was done.
Sincerly.
