[HELP] Optimization Level -O2 issue for NXP's S32K148

[harishn6]

Description

Hi,

Iam trying to run few examples or Applications on NXP's S32K148 hardware by using NuttX RTOS. These Applications or examples mainly for Performance related, So i configured optimization options as below.
CONFIG_DEBUG_CUSTOMOPT=y
CONFIG_DEBUG_OPTLEVEL="-O2"

with this configuration if i generate binary and flash on S32K148 during pin configuration or uart configuration triggering exception_common handler. Please check attached screenshot for more details.

Could you please let me know how to configure optimization level O2 properly or is it a known issue?

Thanks,
Harish Nayineni

@PetervdPerk since you worked on this port, do you have some idea why is he facing this issue?

@harishn6 which board are you using?
If possible could switch frame to the s32K1xx_pinconfig function and see if you can get the port and the pin numbers where the crash occurs?
Most likely it could that for your board the peripheral_clock_config_s the clock for the port you use is turned off.
