I can find the stack top from the memory map, but how do I find the address of the bottom of the available stack area in an LPCXpresso program? I need these addresses to implement a stack usage monitor within my program.
Regards

After some more map file searching I can now setup the stack for background monitoring. Here is the setup code:

#ifdef DEBUG_STACK
    StackBottom = (uint8_t*)((__heaps     & 0xfffffff0) + 0x20);
    StackTop    = (uint8_t*)((__get_MSP() & 0xfffffff0) - 0x20);
    StackPtr = StackTop;
    StackSize = StackTop - StackBottom;
    memset(StackBottom, FLAG_BYTE, StackSize);
#endif
