    I am using the 32k code size limited IAR Embedded Workbench IDE. I think I should be getting close to the code size limit. Where can I look to see the current size of my project as it applies to the limit? What will happen when I exceed the limit? Will it be something obvious like a link error? Or will it appear to work?

      Each time you "download/debug" your bottom results window reports size & results of action. Also - if you've created a .map file you can learn code size broken down by files and individual code blocks.

      Once you surpass code limit "download/debug" will announce that fact. (you do not have to worry about "appearances.")

      Thanks for the reply. I have previously looked at the map file, but had never really noticed all the information in the window when I download.

      Here is what I am seeing now in that window:

      Sun Jan 03 00:08:58 2010: 34325 bytes downloaded into FLASH and verified (1.85 Kbytes/sec)

      Also, the largest address I am finding in my MAP file is 0x00008615, which would correspond to 34325.

      I had been expecting that when anything over 0x8000 showed up in my map file, I would be done.

      But some other info in the map file breaks it down as follows:

      Module ro code ro data rw data
      ------ ------- ------- -------

      ( I have left out all of the individual module info)

      Gaps 22 406 3
      Linker created 44
      ------------------------------------------------------
      Grand Total: 22 482 11 843 19 641


      So maybe it is the "ro code" number (currently at 22482) that I should be tracking. Is it when this number hits 32768 that I reach the limit?

      Thanks again,

      Jill

      I don't know - recall that past applications "squawked" when code exceeded 32KB (or 256KB) on paid system. (and would not download/debug)

      Is it possible that you have a 30 day version - which is unlimited? Always when we have received such "overlimit" message we have been forced to "excise" code-overrun.
