AWR1443BOOST: Continuous Tx mode (FMCW off) settings

Hello Ashish,

You can refer to the configuration in one of the CAPTURE demo in MMWAVE-SDK in the below path ""$mmwave_sdk_01_01_00_02\packages\ti\demo\xwr14xx\capture\capture_demo_script_lvds_cont_mode.txt". This has the "contModeCfg" continuous mode configuration.

Thanks,

Hello,

   I tried loading the below config from the location which was pointed out but didn't get any measurable output power (equipment noise floor is -30dBm)

% ********************************************************************

% * Sample DEMO Script

% ********************************************************************
flushCfg
dfeDataOutputMode 2
channelCfg 2 1 0
adcCfg 2 2
adcbufCfg 0 0 1 1
lowPower 0 0
contModeCfg 77 0 0 8000 0 0 30 1 1024
setHSI LVDS ADC disable
sensorStart

However, the below script enables FMCW modulation and gives a measurable output power (>-7dBm)

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 2 1 0
adcCfg 2 1
adcbufCfg 0 1 0 1
profileCfg 0 77 921 7 114.29 0 0 35 1 224 2107 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 0
frameCfg 0 0 32 0 33.333 1 0
guiMonitor 1 1 0 0 0 1
cfarCfg 0 2 8 4 3 0 1280
peakGrouping 1 1 1 1 229
multiObjBeamForming 1 0.5
calibDcRangeSig 0 -5 8 256
sensorStart

Can you help check if the Con_Tx script needs any change? Also, I'm using AWR1443BOOST, do I need any jumper/device-pack change?

Regards,

Ashish

Hello Ashish,
Before we go to the configuration file I want to double check if you flashed the "xwr14xx_capture_demo_mss.bin" along with the bss binary ? Incase if you haven't done that then you can refer to the mmwave SDK user guide section 4.2 to guide you to flash these using the Uniflash tool.
Once you have that flashed then you run the capture demo with the below configuration to get the continuous mode transmission.

flushCfg
dfeDataOutputMode 2
channelCfg 2 1 0
adcCfg 2 2
adcbufCfg 0 0 1 1
lowPower 0 0
contModeCfg 77 0 0 8000 0 0 30 1 1024
setHSI LVDS ADC disable
sensorStart

Hello Vivek,

    I'm getting an error (Missing command profileCfg). In dfeDataOutputMode 2 , there should be not a need for profileCfg.

contModeCfg  should have been sufficient. Below are the steps and scripts followed:

1. Flash the device using Uniflash tool and files BSS : mmwave_sdk_<ver>\firmware\radarss\xwr12xx_xwr14xx_radarss.bin and mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\xwr14xx_capture_demo_mss.bin
2. Loaded the script you provided. With this we get the below error.

  Below are the steps I followed
