Part Number: IWR1843BOOST
Other Parts Discussed in Thread: UNIFLASH

Hello,

I fail to flash the demo image, and UNIFLASH shows the following error:

I have confirmed:

  * SOP[2:0]==101;

  * CAN-SPI mode switch: SPI mode;

I don't know what mistakes I have made, please help me check.

Thanks.

    Hello,

    Ensuring no other program could be attempting to connect to the sensor's COM port simultaneously, could you try erasing the flash that is currently on the device in the case it is corrupted? Within Uniflash is the "Settings & Utilities" tab, and scrolling near the bottom is a "Format SFLASH" button. Try doing this and then attempting to flash the binary.

    Hello,

    I turned off all the APP, and tried to push the button. UNIFLAH shows the figure as:

    whether flash the demo image or format sflash, the following error is displayed all the time:

    ```

     [ERROR] Cortex_R4_0: XXXX Received unexpected data!!!XXXX
     [ERROR] Cortex_R4_0: Not able to connect to serial port. Recheck the COM port selected.

    ```

    Here is IO port, "COM port" is filled as COM25, right? :

    Hello,

    You are correctly using COM25. If you are able to attempt this on another computer I would try that. If the exact same behavior occurs then I deem the mmWave EVM as faulty, received unexpected data is . Feel free to reach out to TI Customer support and refer them to this thread to validate that an expert took a look at your issue

    Hello,

    I have already tried formatting SFLASH on another computer, and it still cannot format SFLASH. I wonder whether the EVM absolutely can be formatted as long as I power cycle the device in normal circumstances. Is there any possibility that I ignored some steps before format SFLASH? 

    And please help me check the switches on the board:

    Hello,

    You have the SOP switches correct for flashing mode. You can double check this as well with our EVM Setup Operational Modes guide. Setting the HW to flashing mode and ensuring you have the drivers to see the COM ports (which you do since you can see the XDS110 port) is all you need to erase flash under normal circumstances.

    Hello,

    I find something funny that the `format SFLASH` button can work occasionally after I power cycle the device. But just occasionally. I wonder what operations can lead to this situation.

    Thanks.
