Well , i am using crossware cross-compiler at my end ... this tool provides with a 16-bit variable, which goes as __XSP, thats the virtual stack pointer ... this virtual stack is supposed to be framed in the external data memory ... now as far as the initialisation of this virtual stack pointer is concerned, its being handled in the startup.asm file .... in comparison to the usual system stack growth, the virtual stack grows downwards , that means, from high memory to low memory ...now the question is that the virtual stack pointer is being initialised only once, so that gets it located at a particular RAM area , now if the user wants to reserve space for this virtual stack, how does he do that in either Crossware Cross Compiler or Franklin Croscompiler(dos version) ... anybody out there, could help me out ....
