Hard Fault in S32K312 while doing Sector Erase and Write

[ArifJ]

Hello Everyone i am facing one anonymous issue in the bootloader while doing sector erase and write in S32K312 Controller  
i will  explain what are things i have done till now ,

1)i moved all 4 functions of C40Ip driver .srambss section (sector erase ,status,write,write status )
2)for bootloader i allocated 128KB in which hardly i am using 70KB and from next 128KB the Application will start which is 0x00420000

After all these it is working fine i am able to erase and write but with some delay after erase and write in the same block write and erase Now if i am making any changes in the bootloader like i added just 1.c and 1.h file where i am not calling any one of the function from that .c file in the bootloader but suddenly if i add that .c file it is hitting hardfault for erase and write .

i don't what kind of behaviour is this but if i make any changes which are not related to write or erase still it is hitting hard fault 

Please Help and support me in this issue ASAP

Thank You ,

Hello @ArifJ,

You need to debug the fault exception, find the fault instruction, type of the exception etc.

The C40_Ip code should be in the .ramcode section.
