IWR6843AOPEVM: How to input to CLI when debugging a project?

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST, IWR6843, DCA1000EVM

Hello,

I am trying the gesture recognition with my IWR6843 AoP EVM board  with MMWAVEICBOOST board. I have 5V external power connected to MMWAVEICBOOST, drivers are installed correctly and I can see XDS110 debug. I setup correctly the target config and run it.

Now I got the projects DSS/MSS from TI Resource Explorer

Then I tried to load it and debug it, but this project required to start the sensor via CLI, how can I open the CLI during debugging?

My first goal is just setup the chirps and prints all reflected chirps info to the system log. Is there any simple example or starter project for my application, it requires only DSS to read the reflected chirps and calculate the IF (Intermediate Frequency),

    Hi Andrew,

    1. You can open CLI using a terminal program as usual even if the program is running through CCS. The USB port provides JTAG and UART and both work simultaneously so the CLI terminal can be opened as usual.

    2. However, for the gesture demo, you do not need to open the CLI port and the target configuration is hard-coded in this demo and applied automatically at start-up. It is done in this function so you can put breakpoints in this function if you want to see how the config is sent without opening a terminal.

    Have you looked at the SDK out of box demo?

    Hi Nitin,

    Thank you for your reply, yes I found that hardcoded config and just use that for now.

    I checked TI Resource Explorer inside Code Composer Studio, I found 2 demo:

    1. 68xx ISK

    2. 68xx AoP

    I have IWR6843 AoP EVM + MMWAVEICBOOST board, so I should choose 2, right? Not the ISK one?

    I've just imported the project: C:\ti\mmwave_industrial_toolbox_4_5_1\labs\out_of_box_demo\68xx_mmwave_sdk_dsp

    It seems the correct project.

    I have a quick side question, I have 2 modules (they are all same IWR6843 AoP EVM), if they are both loaded with the same firmware, and loaded with the same config (chirp), will the second module "see" the chirp from the first module if they point to each other?

    I want to capture the reflected chirps and draw it, is there any tool for that, I got the DCA1000EVM card here and planning to connect it to the second IWR6843 AoP EVM to capture the reflected chirps. I am expecting I can see the reflected chirps from module 1 (itself) and the chirps from module 2. Am I correct?

    Thanks

    Hi Andrew,

    1. If you have IWR6843 AoP EVM + MMWAVEICBOOST, you should choose the 68xx AoP demo i.e. C:\ti\mmwave_industrial_toolbox_4_5_1\labs\out_of_box_demo\68xx_aop_mmwave_sdk_hwa, not C:\ti\mmwave_industrial_toolbox_4_5_1\labs\out_of_box_demo\68xx_mmwave_sdk_dsp as this is meant for the ISK EVM.

    2. The two sensors, both transmitting and receiving, would not be synchronized at the RF level so you will see interference because of the other sensor, depending upon what frequencies they are transmitting on. Please also note that we do not support receive only operation.

    Thanks
