Hi,

I coupled a SystemC model to the or1ksim as described in the appnote 1 of Embecosm.
Then I wrote some C code to communicate with this model.Up to this all worked fine.

But now I need to debug the c code.

I modified the config or1ksim config file like this:

section debug
enabled = 1
rsp_enabled = 1
rsp_port = 50001
end

then I start the project.

On console I get the SystemC output:

SystemC 2.2.0 --- Dec 7 2011 10:00:50
Copyright (c) 1996-2006 by all Contributors
ALL RIGHTS RESERVED
Seeding random generator with value 0x31cafa99

and then it seems to stop.

Now I try to connect with or32-elf-gdb:

(gdb) file mycode
Reading symbols from mycode...done.
(gdb) target remote :50001
:50001: Connection timed out.

Nmap gives me the following:

nmap localhost -p 50001

Starting Nmap 5.21 ( http://nmap.org ) at 2012-07-06 10:33 CEST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000036s latency).
PORT STATE SERVICE
50001/tcp closed unknown

Nmap done: 1 IP address (1 host up) scanned in 0.05 seconds

As it seems the rsp server is not running.

Is there anything else I have to do?

Hi, I tried the same config and binary from commandline with sim and here debug connection is started. I tried to pass the --srv== argument to the library but this also has no effect. Do I need to call a function of the or1ksim to activate debugging?

Hi,

as I found out debugging of program files isn't possible through RSP yet.
Wiki says this is planed for 0.5.2.

For all of you that don't want to wait until 0.5.2 is released.. here is my solution.
It's a quick 'n dirty solution but worked for my purposes.
