Hello,
I am trying to compile the Demo code with a few alterations in the dss_data_path.c. Mainly, I am adding a new struct that stores x and y positions of objects within a certain area in front of the sensor. When I tried to compile mmw_dss project, it first produced this error:
'Building target: xwr16xx_mmw_dss.xe674'
'Invoking: C6000 Linker'

Then, I played around with compiler optimization, and the previous errors disappeared. However, these warnings appeared:

**** Build Finished ****
The mmw_mss build finished with no errors, but with a suggestion to optimize the compiler. Which I did not do.
When I go into debug mode, I can load the .xe674 file onto the C674X debug probe, but when I load the .xer4f file onto the Cortex_R4 probe, the following error occurs:

I have a feeling that all this still has to do with the inability to to properly fit my code additions in the dss_data_path.c file onto the memory. From looking at different forum posts, the memory partition has to be somehow modified. But I am not sure where to start. What can you suggest?
Thank you.
