For FreeRTOS in S32 Design Studio for ARM Version 2018.R1, please refer to the discussion in https://community.nxp.com/t5/S32K/S32K146-FREERTOS-LSPI-but-SPI-dones-t-work/m-p/1032623

Hi

Seems that you are using S32DS for S32 Platform with S32K1 SDK. Please find the .ld in Linker_Files folder.

For questions on stack overflow, you can refer to the discussion in this thread: check stack & heap size during debug in S32DS

Hope it helps.

Best Regards,
Robin

where can i find __heap_size__ variable or i have to define it so it doesnt select 0x400 as heap size

following are IDE details:

S32 Design Studio for ARM

Version: 2018.R1
Build id: 180815

Maybe you can simply overwrite the 0x00000400 default number.
If you use FREE RTOS, for example, the __stack_size__ is defined in the RTOS.

i couldnt locate either __stack_size__ or __heap_size__ ? yes i am using freertos

the heap defination for freertos and controller core are different right ?

Sorry for the delay. I am not familiar with FreeRTOS.
Please refer to the introduction of https://www.freertos.org/a00111.html

Does overwriting

Maybe you can simply overwrite the 0x00000400 default number.
If you use FREE RTOS, for example, the __stack_size__ is defined in the RTOS.

value in .ld file changes the stack and heap size ?
