Hi All, Just starting with FreeRTOS… Baby steps first – just wanted to try already existed port before doing anything. Got the Experimenter board MSP-EXP430F5438, IAR EW for MSP430 5.20 Evaluation, downloaded a demo,
compiled as Release_Large_Data_Model with no changes whatsoever and… got some errors: Linking
Error: Undefined external “__close” referred in ?fclose ( C:Program FilesIAR SystemsEmbedded Workbench 6.0 Evaluation430LIBDLIBdl430xlff.r43 )
Error: Undefined external “remove” referred in ?fclose ( C:Program FilesIAR SystemsEmbedded Workbench 6.0 Evaluation430LIBDLIBdl430xlff.r43 )
Error: Undefined external “__write” referred in ?fflush ( C:Program FilesIAR SystemsEmbedded Workbench 6.0 Evaluation430LIBDLIBdl430xlff.r43 )
Error: Undefined external “__lseek” referred in ?xfspos ( C:Program FilesIAR SystemsEmbedded Workbench 6.0 Evaluation430LIBDLIBdl430xlff.r43 )
Error while running Linker However, in debug mode everything compiles and runs with no errors. Can anyone shed some light on a problem for a newbie, please?

I just tried a clean build of a clean V6.1.1 installation and using the Release_Large_Data_Model found it compiled with no errors or warnings (IAR V5.20).  The output is below.  Those errors sound like a mis-configured library configuration.  I would suggest unzipping a clean V6.1.1 download and trying it again – and if you get the same problem, try comparing the linker/library settings between the debug and release configurations to see what the differences are. Building configuration: RTOSDemo – Release_Large_Data_Model
