Hi, 

I am trying to use DCA1000 to collect raw data with the demo in the mmWave SDK 3.4, but get an error when starting the sensor:

\rmmwDemo:/>sensorStart \nError: You have provided partial configuration between stop and this command and partial configuration cannot be undone.Issue the full configuration and do "sensorStart" \n\rError -1\n\rmmwDemo:/>

Here is my profile, which is actually the profile_3d.cfg in the demo with a modified line of enabling lvdsStream

    Hi Vaibhav,

    I am using MMWaveICBoost + IWR6843ISK-ODS (ES2.0) + DCA1000.

    Cheers,

    Tom

    Hi TI team,

    I flashed the demo IWR68xx in the MMWaveSDK 3.3, but the problem still exists.

    Do you have any ideas on this?

    Cheers,

    Tom

    Hi TI Team,

    I am guessing the BSS firmware is wrong. A couple of days ago, I tried the mmWaveStudio-2G and failed with a message like 'This release is for AWR24xx and it does not support the device type' when connecting to my IWR6843. I did not see the step of flashing BSS was executed at that moment. 

    However, the error message reported is identical for both SDK3.3 and SDK3.4, as well as their combinations with profiles. I did not find how to flash the BSS firmware in the user guide. Would you please instruct me how to flash BSS in order to verify my guessing?

    Cheers,

    Tom

    Hi TI Team,

    I tested my config file with another ISK-ODS which was not used with any version of MMWaveStudio and failed without luck. So the problem would not be caused by the wrong RSS firmware. Please forget this direction and let's focus on the profile.

    Cheers,

    Tom

    Hi,

    I finally worked it out and the problem was caused by my misunderstanding about the first parameter of the command lvdsStreamCfg, which is the subframe index rather than the enabling flag. Sorry for that.

    It works with the line lvdsStreamCfg 1 1 1 1

    Cheers

    Tom
