K40 IAR: Software reset

[mf_kappa]

Hi

Please advice me howto perform SW reset to the chip: go to c-startup, clear stack, initialize global variables and so on.

(There is also option to force watchdog timeout in order to perfrom reset.)

Thanks

MF

Hi MF,

There are others posts with the details for executing a software reset in the Kinetis K Series using the Cortex-M4 core.

Hi Derek

Thanks for your answer.

I Try to run this code in the post, but it didn't make SW reset:

temp_AIRCR = (unsigned int)scb->AIRCR;

temp_AIRCR &= 0x0000ffff;

temp_AIRCR |= 0x05Fa0000;

  temp_AIRCR |= SCB_AIRCR_SYSRESETREQ_MASK;

  scb->AIRCR = temp_AIRCR;

Do I miss something important?

Another question:

I try to run this routine, from crt0.s file:

__startup();

This routine make SW reset. Can I use it instead of AIRCR register?

Thanks

MF
