Where is the nordic overriden implementation for void __weak sys_arch_reboot(int type)

Hi,

I am evaluating warm and cold reboots, I am seeing no difference between them. I tried tracing sys_reboot definition, ended up with 

/**
 *
 * @brief Reset the system
 *
 * This routine resets the processor.
 *
 */

void __weak sys_arch_reboot(int type)
{
	ARG_UNUSED(type);

	NVIC_SystemReset();
}

For arm core with no handling of type of reboot. Does nordic override this weak definition .?
Where can i find it.?

I am using nCS v2.6.0

Hi,

From what I can see we use NVIC_SystemReset to reset, so no need to override sys_arch_reboot().

You can verify this by debugging and stepping through the sys_arch_reboot().

In this case, it does not look like hot and cold reboot does anything as sys_arch_reboot does not check for "type". Do you agree with this conclusion?

I am afraid I am, had hoped to have cold reboot to systematically uinit & reint everything, 
That allows for a graceful reboot of the system.

Any other alternatives for the same.?

Our reset alternatives can be found at Application core reset behavior.
This is hardware reset behaviour.

I guess the alternative would be to deinitialize everything in software, but I do not think we got any driver to do that for everything at once, so you would have to do it manually for the things that you use in your project.
