S32K148: .elf file size greater than Flash RAM size

[saad_saeed]

Hello,

I working on s32K148. When I build my project (e.g.lwip_s32k148) on s32DesignStudio, the .elf file which is created is greater than 1.5 MB which is bigger than the size of the flash memory. My question is that whether whole .elf file is saved in the flash memory or whether some specific section of this file are saved into the flash memory. And Iam just curious why the size is so large when I build the project lwip_s32k148?

Thanks,

Saad.

The size of the .elf file has nothing to do with the code size, as the ELF file includes lots of other information, for example the debug information. That information does *not* get loaded on your target (this is one of many differences between host and embedded development).
