MEMORY ASSIGNING ISSUE

[Varshini_ext]

Hi,

I am trying to build to integrate a new folder into the existing project in S32K322 microcontroller. But I am facing hardfault issue in Clock driver. From my observation the hardfault is not ocurring because of insufficient memory, there is sufficient memory available in sram. I would like to know that is there any limitations in acessing the sram memory.

Note:

1)I have created a project with dual core(CM0,CM1) enabled.  

2)I am attaching the memory usage of existing project created and a new folder integrated project. 

3)Just adding 700 extra byte size is causing a hardfault.Existing project memory usageMemory usage after integration of new folderimage (1).png

Hi @Varshini_ext,

There are many possible root causes.

Try find more information about the fault exception.

What kind of fault exception is it?

What is the PC address of the fault instruction?

Thank you,
