So I have xwr68xx_mmwavealg_cfaros.xe674 built -- this is just the DSP side though. The file mmwavelib.mak doesn't seem to have any targets for the ARM. It has a main() so I suppose I should just be able to flash this xe674 image onto the IWR6843? Or do I always need an ARM image and a radar ss firmware binary? Could I just use NULL for both of those or do I need to create an mss file with just a main() that halts and use the standard radar ss binary?
