Other Parts Discussed in Thread: IWR6843
Tool/software:
Hello,
We would like to achieve more than 50% of duty cycle on raw ADC data collection. Previously, we've successfully logged raw ADC data with IWR6843 ISK-ODS + DCA1000 on the out of box demo prebuilt binary.
However, in our project scenario, we need to make more than 50% duty cycle. According to the thread below, it seems the only way is to use the prebuilt binary from studio cli tools.
Therefore, we just followed the studio cli guide to give it a try. (https://dev.ti.com/tirex/explore/node?node=A__AB5FdootbDMswAga1mkQ.g__radar_toolbox__1AslXXD__LATEST&placeholder=true) and it didn't work. The flash was sucessful (radar_toolbox_2_10_00_04\tools\studio_cli\prebuilt_binaries\mmwave_Studio_cli_xwr68xx.bin) but the studio cli cannot be started after setting the studio cli configuration properly. The following is displayed.
================= mmWave Studio CLI Application ====================
Configuring mmWave Sensor Device over UART ...
dfeDataOutputMode 1
[ERROR] mmwave device NO RSP for CLI CMD
[ERROR] During Device Configuration [-1]
=========== mmWave Studio CLI Application: Exit ===========
The first thing I've tried to understand is why there is no response for cli CMD. Theoretically, it should be pretty straight forward as long as the right COM port is selected and the right binary is in place. The experiment that I did was with the following steps
1) disconnect DCA1000 from the ODS EVM
2) flash ODS EVM with mmwave_Studio_cli_xwr68xx.bin and then switch to functional mode (ofc power reset afterwards)
3) Run studio CLI application and get the NO RSP fro CLI CMD error.
4) flash ODS EVM with out_of_box_6843_ods.bin (radar_toolbox_2_10_00_04\source\ti\examples\Out_Of_Box_Demo\prebuilt_binaries) and then switch to functional mode (ofc power reset afterwards)
5) Run studio CLI application with the same configuration and get the below Response
My conclusion based on above experiment is that there seems to be something wrong with the mmwave_Studio_cli_xwr68xx.bin. Is it compatible with the IWR6843-ISK-ODS variant?
Best regards,
/Frank
