Original question:

IWR1443BOOST: No data from mmWave Demo Visualizer

IWR1443BOOST: Unable to use the Demo Visualizer properly... No data received

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, UNIFLASH

Please refer to this thread. e2e.ti.com/.../729265. My issue is very similar to this.
I have closely followed this thread but it still did not solve my problem. I am trying to run the out of the box demo for the IWR1443 Evaluation Module. I am using mmWave sdk version 2.1.0.04. No data is being shown in the Demo Visualizer on Google Chrome. I don't even see any console messages. The console messages were printed once but after that I went through setup guide once again just to be sure, and after that the console messages are not printing since. I am able to connect to hardware through google chrome, it says connected to target. At no point does the NERR_OUT LED lights up. I have confirmed that I am using the correct link for Demo Visualizer dev.ti.com/.../ and my SDK version is also 2.1.0 . I tried to run a few commands for that thread to see if the UART is working properly and it gives the correct responses. In the same terminal I tried a few different commands to get the version and here is the output I received:

sdk
'sdk' is not recognized as a CLI command
mmwDemo:/>sdk -v
'sdk' is not recognized as a CLI command
mmwDemo:/>sdk --version
'sdk' is not recognized as a CLI command
mmwDemo:/>v
'v' is not recognized as a CLI command
mmwDemo:/>version
Platform : xWR14xx
mmWave SDK Version : 02.01.00.04
Device Info : IWR14xx non-secure ES 03.00
RF F/W Version : 02.00.00.01.17.10.05
RF F/W Patch : 01.02.00.00.18.09.14
mmWaveLink Version : 01.02.00.00
Lot number : 6121607
Wafer number : 11
Die coordinates in wafer: X = 2, Y = 32
Done
mmwDemo:/>

Also, I don't know what are the commands that the hardware expects through UART, if you could direct me where I could find it, that would also be helpful. But before that, please help me run the Demo Visualizer.

Thanks

    Hi Sarthak

    Have you flashed your device with the SDK mmw_demo binary or the ccs_debug binary?

    Is this error repeatable? If it is can you post a screenshot of the entire visualizer when this occurs?

    Hi Akash

    Okay, after some trial and error, I realised that once I upload the code through CCS (which is one of the last steps in the Out Of The Box demo setup) the CLI on the UART (that is used by the demo visualizer browser app) works as long as I don't press the reset button on the board. Once I press reset, I have to reload the mmw_demo code to the IWR1443 Evaluation Module for it work again properly. Is this expected?

    If yes, pls let me know the reason.

    To answer your question,

    I first used Uniflash to flash the ccs_debug code to the device and then I uploaded the mmw_debug binary using Code Composer Studio. All as per the setup guide.

    Thanks

    Hi Sarthak

    If you use the mmw_demo binary then you do not need to go through the process of loading the .xer4f executable on to the device. If you use the ccs_debug binary then you will need to reload the demo on to the device in CCS for each running iteration.

    Regards,
