Part Number: IWR1443BOOST
Other Parts Discussed in Thread: UNIFLASH, IWR6843, MMWAVE-SDK, IWR1642, IWR1443

Hello,

I'm trying to update the firmeware from 1.0 to the latest version 3.0. I put SOP 0 and SOP 2 to 1 and downloaded the 

"xwr12xx_xwr14xx_radarss_rprc.bin" file from the website.

With UniFlash i selected the correct UART-Port (COM4) and started flashing.

Unfortunatly I got the error message below

My ports in the device manager and the setup in UniFlash

Can anybody help me

Best regards

    Hi Kevin,

    The mmWave-SDK 3.0 is the IWR6843 Devices.

    The mmWave-SDK 2.1 is for IWR1642 ES2.0, IWR1443 ES3.0 Devices.

    The mmWave-SDK 1.2 is for IWR1642 ES1.0, IWR1443 ES2.0 Devices.

    Please use the correct SDK version for the device that you currently have.


    Cheers,

    Thank you for your response.

    Why is it listed as a "Supported Platforms" on the mmwave sdk 3.0 page and the bin File name is "xwr12xx_xwr14xx_radarss_rprc"?

    Nevertheless,  I tried it with the older Version 1.2 and had the same error message.

    "Image loading failed: Not able to connect to serial port. Recheck COM port selected and/or permissions."

    Hi Kevin,

    A few things might be going on here, first I'd check to make sure nothing else on your machine is connected to the UART port.

    Secondly, I'd recommend trying with a different USB cable.

    Let me know if this doesn't work and we can look into this issue further.

    I tried to flash the mmwave_sdk_01_02_00_05 with a new USB-cable and it worked. Afterwards I powered off the board and removed

    jumpers from "SOP2" pin and leaved the jumper on "SOP0" pin. Sadly now the NERR_OUT-LED turns on when the device is in use.
