Hello,
The AWR1243 CSI interface has 4 lanes, can it be configured to have only two outputs？

Hi,

Please refer these mmWaveLink APIs

rlDeviceSetLaneConfig and rlDeviceSetCsi2Config

Hello, thank you very much for your answer.
I checked the documentation and resolved the matter. But there is another question. When CSI 2 is configured as two outputs, the data is only RX0, RX1. Does this mean that there are only two receiving antennas, and the other two receiving antennas are invalid?

If 2 Rx are mapped to 2 lanes of CSI-2 so in that case only 2 Rx are enabled (from channelConfig) to receive the signal.

Please refer this document for more clarity for CSI-2 lane and Rx combination settings.
