Hi,

I have installed the latest or1k-elf-* from github repo. There are
some problems when I try to connect GDB to or1ksim using "target
remote :xxxxx" from GDB.

First, the problem with latest github repo is that when I run or1ksim,
and try to connect GDB to it, I got the following error form or1ksim
and connection is closed immediately:

"WARNING: Test with id 6f7070755371242b not registered. Ignoring." from or1ksim

and

"Remote communication error. Target disconnected.: Connection reset
by peer." from GDB.

Another when installing or1ksim from cvs, is:

"Unable to set flags for vapi socket 7 to value 0x00007fff: Invalid argument"

And the same for GDB.

What are the problems? And how it can be solved?

Regards,
Hesham

I tested the latest or1ksim from the or1k-master branch, and I can't
reproduce the problem here.
How did you invoke or1ksim?
This is how I did it (including the output from when I connect to it from gdb):

Hi Stefan,

I invoke or1ksim with "sim -f sim.cfg", sim.cfg is attached. The
result I got from or1ksim is the following:

Hi Stefan,
I invoke or1ksim with "sim -f sim.cfg", sim.cfg is attached. The
Seeding random generator with value 0xd740c73e

the debug section in the or1ksim.cfg file I used
(http://git.openrisc.net/cgit.cgi/jonas/linux/tree/arch/openrisc/or1ksim.cfg)
looks like this

section debug
enabled = 0
/* gdb_enabled = 0 */
/* server_port = 9999*/
rsp_enabled = 1
rsp_port = 50001
end

also note that I explicitly used --srv=55555 on the commandline in my example.

Great. The problem was about the rsp_* parameters which were missing.
Now it works.
Thanks Stefan!
