S32K142 During initialization, the program runs to DefaultISR

[V_aug]

My schematic has no crystal oscillator, then I configured the clock with only FIRC and SIRC as the clock sources, and then I performed a simple GPIO inversion of the program, and the program ran away图片.png图片.png

The tools used are S32DS for ARM 2.2 and SDK3.0

I tried to turn on other clock sources and found that the clock initialization worked, but the GPIO initialization to read the PCR register ran away again

Hi@V_aug

I see the part number is S32K142W which is not support in RTM 3.0.0.

Could you please install S32 DS V3.4 with RTM 4.0.X and then try again.
