[Contiki-developers] execution trace with mspsim and cooja
Leonardo Steinfeld
I want to get a sky node execution trace simulating a network using
cooja. Since, at this moment it's ok for me to get a single node trace,
maybe the easiest way it is to use the already "Debug On" option of
mspsim, that just print the disassemble to console. I tried the trace
command of the msp plug-in CLI (command line interface) but throws an
exception. Besides that, I need a trace of millions of instructions.
My idea is to add a new CLI (command line interface) command. Inspired
from the implementation of other commands, I do modified the class
DebugCommands to add a new command "debug" to call cpu.SetDebug(true)
(above the code snippet). I recompiled mspsim and copy the mspsim.jar to
contiki/tools/mspsim, so that the cooja build process will copy this
file to cooja/apps/mspsim/lib directory. However, this small change will
prevent compiling cooja. After many attempts I verified that the mspsim
downloaded using git, will make the cooja halt after a few ms of
simulation. So I tried with the mspsim-source-2009-04-30 version, but
this time a exception is trowed: java.lang.NoSuchMethodError:
se.sics.mspsim.core.MSP430.setTrace(I)V.
I've seen there is also a "TODO" in the classs
se.sics.cooja.mspmote.MspMote.java in cooja/apps/mspsim/MspMote.java
(line: this.myCpu.setTrace(0); /* TODO Enable */), and such a methods
there is not in the mspsim version I get. I imagine mspsim.jar coming
with the contiki-2.5.rc1.zp has this method, but it is not clear how to
"call" this method from cooja or even if it is appropriate for my purposes.
I hope if I get a compatible version of the source code of mspsim and
cooja I will manage to implement and use the proposed modification.
Any clue? I would appreciate also any suggestion about how to get an
execution trace.
Best regards,
Leo

DebugCommands.java [snippet]
ch.registerCommand("debug", new BasicCommand("debug, print
execution trace", "<on|off>") {
public int executeCommand(final CommandContext context) {
if ("on".equals(context.getArgument(0)))
cpu.setDebug(true);
else if ("off".equals(context.getArgument(0)))
cpu.setDebug(false);
return 0;
}
});

Please could someone indicate a pair of contiki-mspsim version that work
together.
If I recompile mspsim, regardless of where I get it -git, svn (last
activity 3 month ago), or the mspsim-source-2009-04-30.zip- does not
work with any of the contiki versions. I tried many combinations and I
get compilation errors or runtime exceptions. Above follows some examples.
Best regards,
Leo S.
PS: Last week I post a mail asking for help, explaining the purpose for
recompiling mspsim. Maybe this simple issue of compatibility versions
between mspsim and cooja get lost along the long explanation of my
needs....

I have updated Contiki with latest version of MSPSim.
MSPSim from git and Contiki from git should now work together.

Do you need an instruction trace? I often use the MSPSim command
'logcalls' to trace function calls.

Thanks. I tried the modification I proposed and worked fine.
I need a instruction by instruction execution trace, thanks for your
suggestion anyway.

> execution trace.
If I remember right, there is something like I a next tick hook. You
could try using that to dump the PC. This might even work platform
independent.

Hi,
It seems that the DwarfReader class in mspsim doesn't implement the
getExecutableAddresses and getSourceFiles methods.
Does someone, by any chance, already have code for them, or should I get
to it?
Best regards,
Alexandre
