Hi William,

Thanks for the reply.

I was hoping there was a way to directly use the values entered in the MEMORY section. I do something similar to what you are doing with constants but sometimes I forget to change both values. Maybe I just need a better "memory".

Thanks,
Pete

Hi All, Is there a way to use values from the linker.cmd file in a C program? Such as the .xStack ORIGIN and LENGTH values. Thanks, Pete
