Where in the startup code core 0 for S32R247 is transitioned in RUN0 mode from DRUN mode

[adrianonea]

After a reset the core0 transitions automatically in DRUN mode. Where does the automatically generated software changes the mode to RUN0. Can I leave it in DRUN mode.

I can see that the mode for the other two cores if enabled is set in the hw_init() function

Hi,

Just set debugger read/write breakpoint on ME_MCTL after reset and run your code.

And where your code stops after reset is mode change you are searching for.

There is no problem to run micro in DRUN mode.

Thank you Peter,I just tested and core 0 starts in DRUN mode unlike core 1 and 2 which are set to RUN in hw_init.any particular reason?Can you also point me to the manual where it is explained how to set up the break point the way you described. Apologies for my ignorance.

Hi,

HW_init is part of compiler startup. There is no restriction what has to be done in compiler startups.

If they enable core, i see no issue here. You can always write your own startup.

To set breakpoint just use debugger. (refer to debugger manual for details)
