My intention was to keep the demo under the 32K limit - but I did not take into account the const data used by the html pages that are built into the binary. The executable code is 29K (ish), but then there is 6K of HTML pages. You will have to remove some of the demo files and/or replace the html pages with a simple one pager as a starter. See more info in the thread referenced above. Sorry for inconvenience. I will update the demo in the download accordingly. Regards.
I got the same problem. From error message I guess the demo project would generate more than 32K code which is beyond KickStart 32K (0x8000)limitation.
To make the FreeRTOS demo link without removing any source, you can change the optimizations to Maximum for size, and reduce the library options to minimum printf and scanf. Then it's just BARELY small enough to link. And it still runs!
