Tool/software:
Dear TI Engineer,
Hello! I am writing to seek your help regarding an engineering issue I am currently facing.
I used the Uniflash software to download the bitstream file of the "<out of box 6843 isk mss>" project example in CCS to the AWR6843ISK.
The CLI commands configured through the serial port are as follows

After sending the commands, the EVM responds with:
"Debug: Init Calibration Status = 0x1ffe
Done"
I am able to receive the ADC raw data stream output by the radar through the high - density connector of the EVM.
I can also detect the encoding of the HSI header, and I find that the data following the HSI header in each LVDS data packet is the raw data of the 4 enabled receive antennas.
However, I am unable to find any information about the transmit antennas in the obtained series of LVDS data packets.
During the operation of the radar, 3 transmit antennas work in turn according to the principle of time - division multiplexing. But in the acquired LVDS data, I cannot find which transmit antenna has generated the data of the current LVDS data packet. Therefore, I urgently need the help of your company's engineers.
Thank you very much for your time and support. I look forward to your reply.
Best regards,
