[Mspgcc-users] MSP430 simulator in gdb
This is a follow-on to a previous discussion, which discussion quickly
drifted into language-lawyering:
https://www.mail-archive.com/mspgcc-users@lists.sourceforge.net/msg10619.html
I am trying to use the msp430 simulator built into gdb and am having
trouble getting anywhere.
I'm using Ubuntu 12.04 and the msp430 tools from the repository. (I think
they're actually from Debian.)
I've made the following test program:
volatile int a=0;
int main(void) {
while (1)
a++;
}
Now I want to load it into the simulator, and watch a change.
I compile it like so;
$ msp430-gcc --version

Well, that is unhelpful. Maybe I'll try with an older version of

OK, how about the Java MSP430 simulator mspsim?
$ make run
java -classpath

se.sics.mspsim.Main
Usage: se.sics.mspsim.platform.sky.SkyNode firmware
make: *** [run] Error 1
No problem, I'll just run the thing myself and supply the executable as
argument.
$ java -classpath
build/:lib/jcommon-1.0.14.jar:lib/jfreechart-1.0.11.jar:lib/jipv6.jar:lib/json-simple-1.1.1.jar
se.sics.mspsim.Main ~/hello_msp/test.elf
MSPSim does not currently support the platform 'elf'.
Ah, that's going to be a problem.
Does anyone have other ideas for me to try?

Mark

Re: [Mspgcc-users] MSP430 simulator in gdb
Could you try the gdb from the FSF's source tree? It's version 7.7 and has the RH simulator in it. However, I don't think the profiling results from the RH simulator will be useful to you if you want cycle-accurate counts, but it will show you every single instruction being executed. Also, there's a standalone simulator msp430-elf-run that has some profiling command line options, not sure if those would be helpful. -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

Re: [Mspgcc-users] MSP430 simulator in gdb
I am not concerned about cycles at the moment, just bit-exact simulation of the CPU. The msp430-run program looks useful, thank you. (Except the msp430-run programs packaged by Debian segfault immediately.) I've compiled gdb-7.7 with --target=msp430 and it works! Is there any best way to pass data in / out of the simulator? I guess I can use the run program and set up a memory region for the input data, and write a little main() to feed it into through the algorithm. But if there's an easier way, I'd like to hear about it before I do it the hard way.

Looking at the source, I guess it's probably related to the more complete tic6x CIO implementation.

(FWIW: I now have official support for msp430-elf in BSP430, and lack of a robust system interface is all that's stopping me from being able to develop real applications in the new toolchain.)

Re: [Mspgcc-users] MSP430 simulator in gdb
Will TI be providing sufficient documentation on the CIO API that the msp430 implementation can be completed, thus making the system interface usable in other frameworks? I have enough information to finish the msp interface, I've just had no reason to do so so far. CIO doesn't have exit() though so the RH simulator *also* has its own syscall interface, just for that call. If you just want to exit cleanly a branch-to-self opcode will also trigger an exit(0) from the RH simulator. I personally would wish that newlib prefer APIs that are not proprietary.

Re: [Mspgcc-users] MSP430 simulator in gdb
Is this documented? How can I write drivers to this standard? That's the catch. It's not documented. I have a sample implementation from TI that I used (with permission) to write the simulator/libgloss code. In general, though, the target side works like this: fill up a command buffer at __CIOBUF__ and branch/call an opcode at C$$IO$$ The host sets a breakpoint at C$$IO$$. When it's hit, it reads the command from __CIOBUF__ and does it, which may involve reading data from the buffer and/or writing results back, then resumes the target. The target then looks at __CIOBUF__ to get the results of the syscall. The target side of this is at newlib's libgloss/msp430/ (part in cio.* and part in write.c) The simulator side of this is at gdb's sim/msp430/msp430-sim.c in msp430_cio(). A lot of the to/from buffering is common. -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

I'm interfacing with other external hardware including LCDs and FAT file systems, and I want to re-use the standard libc interface at the application layer. Could you elaborate on this?

As long as I can do the same thing for the msp430 one, I'll have no issues with the default solution being CIO. None of the CIO stuff interferes with the ANSI routines in newlib/libc. You still use printf() and fopen() etc. The CIO code is at the very bottom in libgloss, where it provides a CIO-specific write() call. If you have some other low-level I/O routines, like a serial port or lcd, just provide your own read() and write() functions and the rest of newlib will just work. -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

If the msp430 version supplies a weak definition of _write() (not write()) newlib uses either write() or _write() depending on which the underlying libraries provide. There's no difference between then as far as which you provide. If you'd like to propose changing which of the two newlib looks for by default, I'm OK with that. There's no standard there, and newlib doesn't provide a write() that calls _write_r() regardless. that goes through CIO, we're good because I can replace it *If* you link in libgloss (you don't have to), *and* you don't provide a copy of write(), *then* a copy that uses CIO is linked in via -lgloss. So go ahead and replace it. with one that delegates to a descriptor-specific implementation. If the definitions aren't weak, we're probably not good. It's in a library, one per object. If you provide your own, the linker won't link in the libgloss version. It doesn't need to be weak.

Re: [Mspgcc-users] MSP430 simulator in gdb
Can you elaborate on branch-to-self opcode?
Any branch opcode that branches to itself, i.e. a one-opcode infinite
loop.
1: BR #1b
This also works with any indirect or conditional branch, as long as
the target of the branch is the address of the branch opcode. Here's
the code in the simulator at the end of the branch handler (u1 is
the true/false conditional, which is true for unconditional branches
of cours):
if (u1)
{
if (TRACE_BRANCH_P (MSP430_CPU (sd)))
trace_generic (sd, MSP430_CPU (sd), TRACE_BRANCH_IDX,
J%s: pc %#x - %#x sr %#x, taken,
cond_string (opcode-cond), PC, i, SR);
PC = i;
if (PC == opcode_pc)
exit (0);
}
else
if (TRACE_BRANCH_P (MSP430_CPU (sd)))
trace_generic (sd, MSP430_CPU (sd), TRACE_BRANCH_IDX,
J%s: pc %#x to %#x sr %#x, not taken,
cond_string (opcode-cond), PC, i, SR);
The other way to call exit() (in the RH simulator) is to call 0x181 as
if it were the C function exit(). The simulator traps call to
0x18N and does a syscall N instead of the call. This is a
non-standard interface though, but the only way to call exit() with a
non-zero return code.
What is the inline asm syntax that will give me this?
Just do this:
for(;;);
or this:
#define exit() __asm__ volatile (1: BR #1b)

Re: [Mspgcc-users] MSP430 simulator in gdb
You can do that with the RH newlib as long as you don't link in libgloss's versions of the low-level routines - i.e. remove -lgloss from your link line and add -lbspacm. To clarify: don't link in -lnosys if you're not compiling with -msim or don't link in -lsim if you are compiling with -msim Both of these are linked at the same point as libc and libgcc, by the gcc driver, depending on whether or not you use the -msim option. Both are from libgloss, but have slightly different versions of some functions to compensate for the differences between the simulator and real hardware, mostly the non-CIO system calls like exit(). -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.
