IWR6843AOP: How to create R4 and DSP binary

Part Number: IWR6843AOP
Other Parts Discussed in Thread: UNIFLASH, IWR6843ISK

Our team has created an application for the R4 core and DSP core. Both of these cod bases successfully run within the same code composer studio debug instance as two separate projects within the same workspace. How do we compile/combine these binaries together so that we can flash directly on the development board using Uniflash for stand alone operations?

We are able to put the R4 binary on the chip with no issues, but we cannot flash the DSP binary as a 'meta image' in Uniflash. The R4 binary we compile does not appear to have any of the DSP code we have written within it.

    Hello, 

    Sorry about the delayed response here. Please refer to the .projectspec files for the IWR6843ISK Out-of-Box demo which can be found in the Radar Toolbox ({RADAR_TOOLBOX_INSTALL}\source\ti\examples\Out_Of_Box_Demo\src\xwr6843ISK) . The mss projectspec file contains postBuildSteps for generating the combined flashable image. 

    postBuildStep="${COM_TI_MMWAVE_SDK_INSTALL_DIR}/packages/scripts/ImageCreator/out2rprc/out2rprc.exe ${ProjName}.xer4f ${ProjName}.tmp;
        ${COM_TI_MMWAVE_SDK_INSTALL_DIR}/packages/scripts/ImageCreator/multicore_image_generator/MulticoreImageGen.exe LE 37 0x00000006 out_of_box_6843_isk.bin 0x35510000 ${ProjName}.tmp 0xb5510000 ${COM_TI_MMWAVE_SDK_INSTALL_DIR}/firmware/radarss/xwr6xxx_radarss_rprc.bin 0xd5510000 ${WORKSPACE_LOC}/out_of_box_6843_isk_dss/Debug/out_of_box_6843_isk_dss.bin;

    Looks like ours differed on both the R4 and DSP projects, making sure these matched up better fixed it.
