I did quick check of the hello_world project in RTM 3.0.0 and it works as expected on my side. Did you modify the project? Do you use our S32K146EVB?
Anyway, I can see that you use old version of S32 Design Studio 2018.R1. My recommendation is to use the latest one which is version 3.4:
Latest SDK package is then RTM 4.0.2.
I am not using S32K146EVB.
I have a custom made board which uses FS32K146HAT0VLQT
has an external crystal oscillator of 16Mhz attached to:
pin 18 PTB6/LPI2C0_SDA/XTAL and pin 17 PTB7/LPI2C0_SCL/EXTAL
The board has a 10 pin Jtag interface for Pe micro universal multilink.
The hello world app from the example runs on debug_RAM mode
I was able to run the LED blink program using bare metal , no SDK , on debug_FLASH mode
see the attachment
But i want to use the SDK for future development.
Let me know if you need more details.
