i have downloaded freeRTOS & SDCC. When i m compiling cygnal demo example, it gives  
syntax error in portable.h when compiling any of the source files like main.c, serial.c, port.c, tasks.c as follows :  
&nbsp; “portable.h:140: syntax error:token-\> ‘\*’ ; column 16. stdout: invalid arguments”.&nbsp;

Are you compiling it using the makefile supplied in the download (from the command line)?&nbsp; Or trying to use it through the IDE.

The makefile was created before the IDE supported SDCC directly.
