Hi, I've started work on the OpenRISC 1000 project. I've used this page to setup my software: http://www.opencores.org/projects.cgi/web/or1k/gnu_toolchain_port I don't have the hardware setup yet, but I wanted to work with the architectural simulator. The problem is that there seems to be little to no documentation online on how to do this! Where do I get the appropriate software to install and how do I use it? I've basically installed the GNU toolchain and now am stuck.

I'm having trouble installing the or1ksim in Cygwin. Has anyone done this
succesfully? It doesn't build correctly. Any ideas?

It gives miltiple errors like this first one:

..
gcc -g -O2 -DOR32 generate.c -o generate
/cygdrive/c/Temp/cc1IegwA.o(.text+0x8a4): In function `gen_eval_operands':
/or1k/or1ksim/cpu/or32/generate.c:192: undefined reference to `_op_start'
..

Sorry for the double email.

When I meet a error message, I do a manual step to compile the source code. And it works in my enviroment. Just for reference, you can try it.

Thanks for the help all. I'm still struggling through. Everyone's advice has worked thus far. My next concern is how to get GDB to talk to the simulator. I see how JTAG is talking to a port but now how to get things going with the simulator in place of a board. Example: (gdb) target jtag jtag://localhost:9999 jtag_connect_to_server: connect failed errno = 111 Connection refused So where do I insert or1ksim? In place of jtag or its destination port? I apologize for the stream of simple questions. But I've been basically employed in a project using OpenRISC and Unix at a university that doesn't speak my native language. So I'm always a little lost.
