IWR1443: IWR 1443 EVM

Part Number: IWR1443
Other Parts Discussed in Thread: UNIFLASH

I have been trying to reflash the EVM using "uniflash 4.2.2.1692" and "mmwaveSDK v1.01..00.02-Linux"

I have followed the instructions as given in the userguide and my board does not get reflashed for some reason.

I have attached a pic of where I am struck at in the process and from there on, I receive no sort of response from the sensor board.

Thanks in advanced

    Hi Siddarth,

    Can you confirm you have added a jumper to SOP2? Can you confirm you've set the correct COM port in the Settings & Utilities pane?

    Hi Akash,

    Yes, my SOP2 has a jumper on it and the COM port is also rightly mentioned. I am positive about it because, when the port is changed to 1 or when jumper is removed, it directly pulls out an error in loading images. Whereas, this issue of not responding anything happens when I am on the right track.

    Cheers,
    Siddharth

    Hi Siddarth,

    You are populating both SOP2 and SOP0 before power correct? Are you receiving the error message in the console after break signal is set?
    [3/27/2018, 10:09:54 AM] [ERROR] Cortex_R4_0: Initial response from the device was not received. Please power cycle device before re-flashing.
    [3/27/2018, 10:09:54 AM] [ERROR] Cortex_R4_0: Not able to connect to serial port. Recheck COM port selected and/or permissions.

    Would you be able to post a picture of your board? We need more information in order to answer your question.


    Cheers,

    HI Akash,

    I am not getting any sort of error message after the break signal is set. What I get is "Opening com port /dev/ttyACM0..."

    Post this, I don't get any response. I have attached picture of that in the initial query I had set up. I am attaching the picture of the board as you requested. Please find it.

    Cheers,

    Siddharth

    Hey Siddharth,

    in your picture I can see a jumper on SOP2, but not on SOP0. I think to flash your device, you need to place BOTH jumpers.
