IWR6843ISK: CFG port connects. But, Data port does not connect.

I flashed with C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo.bin. Flashing was successful.

And, then power-cycled, pressed RST. Now, the CFG port connects. But, the data port does not connect. What can I try? I had earlier flashed another lab and loaded a config file. What is the chirp config file for default demo? Do I have to load it?

    Oh... It was the result of a mistake I was making in flashing. In Uniflash, the correct sequence is - First, you do "Format SFLASH" and then, "Load Image". Mistakenly, I was first loading and then formatting, thereby erasing the image. Now, with the correct order of flashing, both COM ports connects.
