Move stack to RamAHB32

markvanderheijd — Wed, 22 Mar 2017 13:33:25 GMT

I have a problem, my local variables change value without any reason. So i think my stack and heap are overlapping each other. Is it possible to move my stack to my second ram location (RamAHB32)? On the internet i only found a way to move the stack and the heap to the second location. EnhancedManagedLinkScripts - ** Code Red Support Site ** .

I'm using the lpc1766 processor.

Thank you in advance,

In LPCXpresso IDE - the simplest way to to do this would be to add the linker option:

--defsym=__user_stack_top=__top_RAM2

to MCU Linker - Miscellaneous - Other Options box in Project Properties. You can move the heap in the same way if required, as described in https://community.nxp.com/thread/389026

Alternatively, you can do this by making a minor modification to a Freemarker Linker Script : Freemarker Linker Script Templates

Note that in MCUXpresso IDE, you can do this more directly via a new entry in the Managed Linker script page of the Linker Settings. Please see the MCUXpresso IDE User Guide for more details (downloadable from the Documentation tab of http://www.nxp.com/mcuxpresso/ide
