[ECOS] Running ECOS using the PPC simulator

[ECOS] Running ECOS using the PPC simulator

[Ilan Ovadia]

Hi,
I've build an  environment for the PowerPC using the configuration tool
(PowerPC architecture, minimal simulator).
I tried to execute one of the tests by:
1. opening a bash shell
2. typing: powerpc-eabi-gdb -nw install/tests/kernel/bin_sem0
    I've got the "gdb" prompt
3. typing: target sim -f
BASE_DIR/packages/hal/powerpc/sim/v1_1/runtime/tree
    I've got the message "Size or register ro (0) incorrect (1 instead
or 4))Connected to the simulator
4. typing: load
    I've got no message
5. typing: run
    I've got the message: Starting program:
/ecos/ppc/install/tests/kernel/bin_sem0.exe
    and the program never returned. When I hit the CTRL+Break I've
noticed
    that ECOS was running functions from clock.cxx.

Can any one assist.

Thanks,
Ilan

P.S.

 If i'm trying to run another test (clock0 for example), I get an error

"
message after the run command: cpu 1, cia 0xfff02008: program interrupt -
privileged instruction

Program terminated with signal ?, Unknown signal.
The program np longer exists.
"

thanks,
Ilan

Using the default configuration?

Here's the GDB output when I do it:

A program never returns. If you just want the GDB prompt back, you
could set a breakpoint at cyg_test_exit before starting the test.

Or you can break execution. When I press C-c after the above output, I
get:

Program received signal SIGINT, Interrupt.
cyg_test_exit () at /local/ecc/ecc/ecc/infra/current/src/tcdiag.cxx:100
100             ;
Current language:  auto; currently c++
(gdb) 



I don't see the problem you reported when running the clock0
test. Notice that the problematic address is in ROM space. The PowerPC
simulator can only run tests configured for the minimal simulator, and
these are normally loaded at address 0x4000. 

Perhaps you ran a test configured for the Cogent board by mistake?

Thanks,
Jesper

The problem is while I'm running the bin_sem0 test
I don't get the message

PASS:<Binary Semaphore 0 OK>
EXIT:<done>

Actually, when I set breakpoints in the functions
located in bin_sem0 file, the debugger doesn't stop.
It seems like  ECOS doesn't succeed to complete
the initialization phase and run the test.

Ilan

Are you using the default configuration? 

Could you try building the library and tests with the default
configuration in a new build directory to see if it makes a difference
(this would ensure that settings from a previous configuration/build
are not being used).
