Bootup Delay on S32K146EVB Micro-Controller

[Nibesh]

#Help

Hello! I’m currently working with an S32K146-Q144EVB board and running code to blink an LED.

• I want to verify the bootup delay for this setup. Unfortunately, I haven’t found much information in the Reference Manual or the S32K1xx Clock Calculator Guide.
  There is no Timing Diagram for Power on Reset too.

1. Specific Query:

   • My main question is: How much time does it take for the MCU to jump to the application after a normal reset?
   • Currently, I’m achieving a bootup delay of 4.22 milli-seconds (as shown in the attached Logic Analyzer image).

2. Request for Clarification:

1. • Could you please correlate my doubts and provide insights?
   • I’m also open to feedback from anyone who can help.
   • It’s surprising that technical folks at NXP haven’t responded to such a straightforward question yet.

Hello Nibesh,

I just replied to your other thread on this topic:

https://community.nxp.com/t5/S32K/Power-on-Reset-of-S32K146-Q144EVBVEVB/td-p/1874579

It is specified in the DS:

The execution starts at the reset vector, it goes through the startup code and your custom main.c configuration code before the SW goggles the GPIO, and this cannot be specified by NXP.

Regards,

Daniel
