Hi all,

In my program, I want to run the program on eCore twice. But it always stop at the second loop.
Do I have to reset the group each loop? Or something is wrong with the local memory at the second loop?
Any suggestion?
Thanks!

When the core program returns from main, it executes TRAP and stops. This will be fixed in a future SDK release .

You could try just ending your main in "while(1);"; it will use more power when idle but should let e_start() reset the chip and re-call main(). Or just call e_reset_group() or e_resume() before calling e_start(). e_resume() will continue after a trap but it might be in a loop iirc.

Also note that data will not be reset so any static initialisers will appear not to be run. And only bss off-core will be cleared (if the linker script defines any).

Thanks for your suggestion!

Actually, e_reset can make the program work. But I have just tried e_resume(), which also stops at the second loop.
Does this mean I have to call e_reset_group() in the loop? Is there any other way?
I think my problem is quite similar with stevenc.

I just try to do a e_reset_group before the e_start_group, and it works fine.
I see it as a trick in cause the program executes TRAP and stops as timpart mentioned.
To me we loose time doing so, and hopefully this will be fixed.

Thank you, notzed!

I think e_reset_group() should be fine for the moment~

@notzed you are absolutely right, and it works fine that way anyway.
