hi,I’m trying to compile the demo1 program for the PIC18 using MPLAB V6.3 & Student version of C18 Compiler – with no success yet. I get the following error + some warnings about some locations being redundant in serial.c. MPLINK 4.02, Linker Copyright (c) 2006 Microchip Technology Inc. Error – could not find definition of symbol ‘vStartPolledQueueTasks’ in file ‘C:Documents and SettingsHP_OwnerLocal SettingsTempFreeRTOSDemoPIC18_MPLABmain1.o’. Errors    : 1 anybody got any suggestions  ? – thanks.

Did you update the path names in the project file as described on the FreeRTOS.org site?

Thanks for the reply, yes I did change the Path as directed but still the error.?
