Hi NXP Team,

I am using the default configuration settings in our project(S32K144 controller) , need to find the boot time(time between hardware reset to main).

how to find the boot time ?

is there any way to find the boot time in S32 Design studio IDE?

how much is the boot time for default configuration of the S32 Design project?

Regards,

Ambarish

Hello,

only boot time, which is defined, is time from power on reset to first executed instruction.

Time from first instruction to reach main function is application dependent, because there is startup code which can be different for every application.

It is not possible to find this time in S32 Design Studio, but you can simply measure this time.

Connect oscilloscope to reset line (first channel). Place the code which toggle some pin into your main function and connect the oscilloscope to this pin (second channel).

Now set trigger to reset line (change from logic 0 to logic 1) and measure the time to pin toggle.

Regards,

Martin
