Find out how much stack is being used

I tried the FAQ idea  "How do I find out how much stack my program uses?" but the stack is not initialized. I'm using Crossstudio 1.4 Build 3 programming a MSP430f1611. In this case the preprocessor definition that should be used is INITIALIZE_STACKS  or INITIALIZE_STACK ? I tried  them both in the preprocessor options of crt0.asm but neither worked: when I inspect the memory just below 0x3900 there is random data, not the expected 0xCC watermark byte. What am I doing wrong?

Thanks.

  I still would like to know how to get stack usage in CrossStudio for MSP430. Have there been any developments on this? This really ought to be implemented by now, no?

  Just initialize the stack contents to 0xFF, and periodically see what the low-level watermark is.  If you use CTL, stack usage is available in the Threads window.

  Isn't CTL for ARM?

  CTL is our own tasking library that provides a consistent API across ARM, MSP430, and AVR.  So yes, it is for ARM, but it is also for MSP430 and AVR.

  I'm sorry, I can't figure out how to get CTL for MSP430. Could you link me or explain how to get that, please?

  It's in the product.  Read the documentation.

  That's some top notch support for a $1500 product. Thanks.
