Error of trying to run example program with TDD

Question

Hello everyone, I'm trying to use the CN0566 instrument to verify FMCW experiments. I saw this person's video online (www.youtube.com/watch used his program on GitHub for testing(github.com/.../FMCW_RADAR_Waterfall_ChirpSync.py). I updated my version to V0.39 according to the CN0566's QUICK START instructions, and also updated AD9364. However, after the update, I received an error message, seemingly indicating a conflict between the 1r1t mode and chan1. But the program strongly requires an update to V0.38 or higher. Could you please help me figure out what I did wrong?The program I'm testing is FMCW_RADAR_Waterfall_ChirpSync.py.

Yes, this error is because you are in 1R1T mode. You need to be in 2R2T mode. When updating the firmware, Pluto reverts back to 1R1T mode. To set it to 2R2T mode, follow these instructions:
