I can't call any function

Hi I am a newbie and I am french.
I have set an environment for developping on my computer and now I try to test some code on the PS2 but can't can't call a function, but the others operations do not cause an error.
I have try to exucte code like this :
Code: Select all
void test()
{
}
int main()
{
int var;
var = 2*5;
for (var = 0; var < 100; var++)
;
test();
return 0;
}
When I don't call function test() TV stay on naplink screen (I can see status of cable and computer connection), but when I call the test() function I have an error screen with many adresse (I don't understand this screen).
I use the Makefile of the star simulation (the first exemple in the tutorials)
PS : I use NapClient with an usb cable.

I have try to compile without any lib this code but there no effect, I have always the same error :
Code: Select all
Naplink Exception Handler
Exception error : address Error (store)
Status: 70030C13 EPC: 0040015C BadVaddr: 81FFFFD0
...
Someone knows how can I analyse this screen?
I have remove -fnonnull-objects CFLAGS option in Makefile because I have the massage "cc1: unrecognized option "-fnonnull-objects", my probleme can come to here?

...you can try to generate ".map" file, which will contain memory addresses of your data and functions. Then you can compare value of EPC from the exception dump with these addresses to see where approximately the program crashed. ".map" file can be generated by adding this: "-Xlinker -Map -Xlinker <map_filename>" to the linker's command line...

Er... and if your function isn't a pointless empty function?

I now, I am trying to recompile ee-gcc

@Drakonite: then at least there's some hint about actual location of the problem :). In case of SMS it helped me a lot...

Finally I have install the packsetup (
http://ps2dev.org/ps2/Tools/Toolchain/P ... _for_Win32) but I have always the same error and all sample that i have compile crash. And after the Error screen I need reboot manually the PS2 because the Napclient reset have no effect (stay on a black screen).

The only one sample that I can compile is pad_exemple.elf, but if I add a return before the end the programme crash.
And know I try to understand why I can't call just a printf.
I need to do something special to init or close the CPU or anything else?
I need to do something with my .elf file before use napclient?
