IWR6843AOP: Compiling a modified version of the Area Scanner Lab

Part Number: IWR6843AOP
Other Parts Discussed in Thread: UNIFLASH

Hello,

I am doing a simple modification to the area scanner lab and trying to compile the changed project using Code Composer Studio.

I am using CCS version 12.3.0.5 and SDK 3.5.0.4 targeting IWR6843AOP chip.

I have two questions:

1) The original area scanner lab comes in DSS and MSS projects, which one should be used to compile my changes?

I tried to compile the original Area Scanner Project (without any modification), and only the DSS project was built without errors. The original MSS project gives the following error when I try to rebuild it using CCS


#137 struct "MmwDemo_RFParserOutParams_t" has no field "centerFreq" mmwdemo_rfparser.c /area_scanner_6843_mss/mss line 907 C/C++ Problem

2) I thought that the DSS project may be sufficient to generate the binary image, and since it was compiled successfully using CCS, I made my changes to the code in the DSS project and the built was completed without errors. However, loading the generated binary file into the IWR6843AOP chip using UniFlash failed giving the following message.  

 Header of /area_scanner_6843_dss_aop.bin file indicates it is not a valid file to flash to IWR6843AOP: 0x43525052

I would appreciate it if you can kindly guide me to what steps I need to do to generate an acceptable binary image of the project.

Many thanks,

Abd

  • Hello Abd,

    Are you getting these issues when importing unchanged default projects? The order of operations is importing the default demo's MSS and DSS into CCS, rebuilding DSS then MSS in that order, and then making changes. Once you make your changes you will flash the .bin in the MSS folder via Uniflash to the device. If using debug mode with breakpoints you flash the .xer4f and .xe674 files in CCS

  • Hi,

    Thank you. Problem was resolved by simply reinstalling CCS. All works fine now, original and modified versions of the projects.

    Thanks,

    Abd
