Subject: [openrisc] What cable you are using for debugging or1200?
To Mark:Thanks! That's more like what I want. I would like to try your
suggestions if I got some free time. Unfortunately I don't have much
neither. :) But I believe some of them will finally work. It is only a
matter of time.
To the List:
Meanwhile I am also trying to use the or1ksim to setup an off-line
simulation environment. Now I meet a problem, which is I cannot call
the or1ksim in GDB by passing a command like "sim r". Every time the
GDB returns "Command not supported on this target." Can somebody give
me some hints please?
I am working in Windows/cygwin, with the pre-build tool chain package
downloaded from the "GNU tool chain port" page. My simulator works at
port 9999 and or32-uclinux-gdb has successfully connected to it by the
command:
(gdb) target jtag jtag://localhost:9999
Then I can "load", "step" and "info spr SYS ..." and whatever, but
cannot use "sim" command to control or1ksim directly. It is strange
because the manual says it is possible to do like this. And I would
like to use this feature because "sim r" is much better than "info ...".
By the way, I tried "(gdb) target sim" too. It returns "0x1234 in ??
()", but cannot respond "step" or "next" or other commands after "load".
Thanks.
