CCS/LAUNCHXL-CC2640R2: Code composer studio shows that the "project_zero_cc2640r2lp_app.hex" file has been programmed successfully, but in actual, it does not program the software on CC2640R2 Launchpad board.

Tool/software: Code Composer Studio

Hi,

I am trying to program the "project_zero_cc2640r2lp_app.hex" file using code composer studio, after building my project. I have programmed the .hex file using "debug" key as well as "Flash" key in the code composer studio. CCS IDE shows that the file has been successfully loaded, but my board does not work.

If I load the same hex file using SmartRF Flash Programmer 2(ver 1.8.0) utility, everything works fine.

The surprising thing is, I was able to program the . hex file using code composer studio until last Friday and suddenly from yesterday, it stopped working.

SDK used for my project is  2.20.0.49

Could you please let me know the reason of this behavior of CCS IDE and how I would be able to solve this issue.

Thanks and Regards,

Shruti.

    If you load the *.out file instead, does that work?

    What has changed since then? Did you update CCS in any way? What is the full version number of CCS that you are using?

    Thanks

    Hi Ki,

    Sorry for the delayed response.

    Actually, I am using AUX_AS_RAM feature to use Aux RAM and reduce the SRAM consumption. For this feature, I have made some changes in the code and I have put main.obj file in the linker file while trying out some combinations of putting .obj file in linker file. Due to this, control is stalling & I couldn't see my application running.

    When I removed main.obj file from the linker file, everything worked just fine.

    Thank you for your response.
