 8. Repeat the previous step for github project CoreNG. The folder name should be left as CoreNG (or renamed from CoreNG-dev to CoreNG if you downloaded a dev build).
 
-9. If you want to build version 1.19 or later of the Duet WiFi build of RepRapFirmware then you also need to download and add project DuetWiFiSocketServer. Alternatively, just download file src/include/MessageFormats.h from that project and put it somewhere on the include path for RepRapFirmware.

 12. Load Eclipse and tell it to import the CoreNG and RepRapFirmware projects, also FreeRTOS, DuetWiFiSocketServer and RRFLibraries if you have included them.
 
 13. The build depends on the Eclipse workspace variable 'ArmGccPath" being set to the directory where your arm-none-eabi-g++ compiler resides. For example "C:\Program Files (x86)\GNU Tools ARM Embedded\7 2018-q2-update\bin" on Windows. To set it, go to Windows -> Preferences -> C/C++ -> Build -> Build Variables and click "Add..."
 
-14. Build CoreNG first, also build FreeRTOS and RRFLibraries if needed. Then clean and build RepRapFirmware (the clean step is needed to make Eclipse notice that the output library files in the other projects have been built). The Duet WiFi and Duet Ethernet builds of RRF use the SAM4E_RTOS builds of CoreNG and RRFLibraries and the SAM4E build of FreeRTOS. The Duet Maestro uses the SAM4S_RTOS build of CoreNG and RRFLibraries, and the SAM4S build of FreeRTOS. The Duet085 build of RRF (which also runs on the Duet06) uses the SAM3X build of CoreNG and RRFLibraries. The RADDS build of RRF uses the RADDS_RTOS build of CoreNG and the SAM3X_RTOS build of RRFLibraries.

 Note: you do not need to build the DuetWiFiSocketServer project, but it does need to be in the workspace because the RepRapFirmware project uses one of its include fies.
