Absolute placement of stack

Tamiryan Michael

Hello,
I'm using an LPC2478. Can you refer me to the place in the documentation of RealView where absolute location of the stack is demonstrated? I have found some references but they all require to re-implement "__user_initial_stackheap", something I don't want to do. All I want is to place my stack in a predefined, arbitrary location. Can I even choose such a location? I could not find limits in the documentation...

Thanks in advance

    thanks for the link. a colleague of mine came up with a clever idea that solves both problems (sharing internal RAM by 2 binaries that run in parallel and data abort due to R13 accessing outside of its restricted internal memory region): both binaries can access all of the internal RAM but (here comes the trick) they define (and place using the scatter file) a large array in the memory region of the other binary so that all its RAM variables are mapped implicitly into a restricted zone. the other binary does the same, but "mirror imaged".
