Using FreeRTOSV7.5.0 and eclipse for DS-5 renesas How to buil and test a FreeRTOS-Plus demo for example FreeRTOS-Plus-UDP on eclipse for DS-5 renesas?

Why are you using such an old version?

I would suggest the following:

1) Ensure you DS-5 FreeRTOS project is building, debugging and executing on your target hardware.

2) Add the FreeRTOS+UDP source files into the project. Basically all the files that reside outside the portable layer. You can look at the projects files used by the demos for a reference: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/EmbeddedEthernetExamples/RTOSUDPCLIWindowsSimulator.shtml http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/EmbeddedEthernetExamples/RTOSUDPandCLILPC1830_NGX.shtml

3) Implement the macros that are necessary to build the code with DS-5 as described here: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/EmbeddedCompilerPorting.shtml

4) Implement the MAC interface as described here: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/EmbeddedEthernetPorting.shtml http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/Networkinterfacefunctions.shtml again, you can use the demo projects for references.

Regards.
