IWR1642BOOST: Unable to print data in teraterm - High accuracy lab

Part Number: IWR1642BOOST

Dear TI,

 am using a IWR 1642 EVM for high accuracy lab. I followed the steps given in the user guide and i was able to run the high accuracy visualiser successfully in CCS debug mode. I am intending to analyse and interpret the data being sent by the EVM to the high accuracy visualiser GUI. For that, i loaded the config file in the GUI and disconnected the GUI and i tried using Tera Term for getting the serial data being communicated (with data port baud rate set to 921600). However, i am getting garbage values. Screen shot attached. I request if you can help me to get a valid data in teraterm. Thanks in advance.

    Hi Jagath,

    I'd recommend opening a separate Tera Term on the UART port and input the chirp config commands manually? Make sure the visualizer is completely closed when you do this.

    Hi Akash,

    Thanks a lot for your response.

    I tried as u had suggested. the outcome is same.  (attaching the tera term screen shots). Further, i tried to pass the CLI manually through serial terminal of CCS. I ended up with similar same garbage value to be printed on the CCS terminal as well (PS - the data port as per high accuracy lab with a baud rate of 921600. but in CCS serial terminal the maximum allowable baud rate is only 115200. so had to choose 115200 in this case). Is there any other way around or any other terminal software which may be of use for me (i am using windows 7). i just want to see the range being continuously printed on the serial port terminal.

    Thanks in advance

    Dear TI,

    I kindly request you to help me out to just see the data coming out of iwr 1642 UART in any serial terminal rather than in High Accuracy Visualiser. Thank you in advance.

    Hi Jagath,

    This actually looks correct, the data should be coming out of the Auxiliary Data port very quickly.

    You will need to decode the data, as is performed in the visualizer, in order to interpret it.
