Linker file

I have a project in IAR for MK10FN1M0xxx12. I suspect my linker file is not good. I took it from some project.

Can you look into it and tell me if it's good for MK10FN1M0xxx12?

If I compare it with the one provided with IAR - I see some differences. But I cant use the IAR linker cause the startup code uses

define exported symbol __VECTOR_TABLE = 0x00000000;
define exported symbol __VECTOR_RAM = 0x1fff0000;

define exported symbol __BOOT_STACK_ADDRESS = __region_RAM2_end__ - 8;

and I don't have these defines in the original IAR linker file.

 

actually it contradicts the memory table
