Tool/software:
HI,
I’m trying to enable multiple TX antennas for a set of chirps in the OOB demo for AWR1843AOPEVM. According to the mmWave SDK user guide, this should be supported. However, when I try this configuration, I receive the following response after issuing the sensorStart command:
"
Debug: Init Calibration Status = 0x1ffe
Error -1
"
This issue occurs with both advanced and non-advanced configurations. Here is the configuration I am currently using:.

In the above setup, I have the following chirp configurations:
chirpCfg 0 0 0 0 0 0 0 7

chirpCfg 2 2 0 0 0 0 0 7
chirpCfg 3 3 1 0 0 0 0 7
chirpCfg 4 4 2 0 0 0 0 7
chirpCfg 5 5 3 0 0 0 0 7
However, if I modify the configuration to:
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
chirpCfg 2 2 0 0 0 0 0 4
chirpCfg 3 3 1 0 0 0 0 1
chirpCfg 4 4 2 0 0 0 0 2
chirpCfg 5 5 3 0 0 0 0 4
I am able to obtain data without any issues.
I also tested this in the mmWave Demo visualizer, and received an "invalid configuration" when trying to enable multiple TX for same set of chirps
There I got the error, invalid configuration.Could you guide me on how to fix this?
Thanks
Regards
Gayatri
