Hi,

As far as I know the 64 pins has a smaller ram size. This means that you have to manually change linker file.

Please do these steps:

1. Right click on your project and select Proprieties 

2. Select C/C++ Build -> Settings-> Standard S32DS C Linker

3. Add the right linker file 

Please don't add the same linker file as on this picture because I don't know which release you are using. You have to check the linker files available in your release. I think it should be something line S32K142_16_ram/flash.ld.

Best regards,

Razvan

Hi Daniel Carlquist

The change of package in the Processor expert setup only gives you the ability to configure those pins, it shouldn't be related to the memory distribution and bss zero-initialized data section.

Could you verify that the linker file that you are using does have the memory sizes of the S32K chip that you are using? Also, only to verification, could you check what are the values of bss_start and bss_end in the while loop where you are stuck?

Have a great day,
TIC
