I would guess either the PATH variable was not set correctly (environment variable), or the makefile contains paths that are not correct for your machine.

Actually, I seem to remember that the Cygnal demo needed some libraries to be downloaded from the FreeRTOS site. Check the documentation page for the port to see if there is a link.

Hi There,

I am also having some problems with this demo, however I did get further than this so I’ll try help you out.

On the demo page read the text under the heading "Compiler, header file and library versions", there is a file you need to download, unzip and place in sdcc/lib/large.

You will then need to add "–lib-path c:/sdcc/lib/large" to the make file.

See my post "[http://sourceforge.net/forum/forum.php?thread\_id=3081738&forum\_id=382005](http://sourceforge.net/forum/forum.php?thread_id=3081738&forum_id=382005)" for details.

Please post back if you get it all running and working then maybe you can help me?

Thanks,  
Frazer
