Unreliable R52 Core Boot on S32Z2 EVB – Requires Multiple Power Cycles / Resets to Work

[karthik_nikil]

Hi,

I am working with the S32Z2 development board. I have successfully built, flashed, and run code on the Cortex-M33 core without any issues.

However, when I try to run the same type of application (e.g., a simple LED blink) on the Cortex-R52 core, I am facing a very unreliable startup behavior.

• The R52 project does not work properly on the first attempt.

• It requires several power toggles, ON/OFF cycles, or board resets before it works.

• Even after these attempts, it only runs successfully one or two times before failing again.

• When it fails, there is no output, and the LED does not blink.

Please guide me on how to achieve reliable, consistent booting of the R52 core on the S32Z2 EVB. Any insight into the root cause of this "reset-dependent" behaviour would be greatly appreciated.

Thank you in advance for your support.

BR,

Karthik
