Flag Status: SRS1_JTAG

Good Mornig:

I'mtry tu check the SRS1_JTAG flag of MK60FN1M0VMD12 by Keil environment.

this flag is inside of System Reset Status Register 1.

And when I am debugging with ULINK 2 by UVision, this flag is not activated.

That is the raison?

for check the debug mode is activated, Who can i Used this flag?

There is another way to check if jtag is connected?

Thank you very much.

It can be very userful.

Hello Albert Martin:

I did not get the first part of your question very well. But if you want to detect when the K60F MCU is in Debug mode, I guess you can use the ARM register DHCSR (Debug Halting Control and Status Register), which is at address 0xE000EDF0. Example below:

#define DHCSR_REG (*(uint32_t*)(0xE000EDF0))
int main (void)
{
  if(DHCSR_REG & (uint32_t)(0x1))
  {
    // Debug mode
  }
  else
  {
    // Standalone mode
  }
}

I hope this helps!

Regards,

Jorge Gonzalez
