IWR1642BOOST: Serial Port Grey

IWR1642BOOST: Error in UniFlash -- Cannot read property 'DS' of undefined

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: UNIFLASH

Hi,

I` m now trying to flash the demo executable (C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr16xx\mmw\xwr16xx_mmw_demo.bin) to on-board Serial Flash on IWR1642BOOST, but i saw the error of "Cannot read property 'DS' of undefined" when loading the image. It looked like this:

What should i do for next ?

Please note:
- IWR1642BOOST (ES1.0 device mounted) connected Windows 10 PC via USB cable and 5V powered.
- mmwave_sdk_01_02_00_05 has been installed to its default path
- UniFlash Version: 4.3.1.1835 (Latest) has been installed to its default path
- SOP2 has been put on the board for flashing
- Latest FTDI driver has been installed (2.12.28) and validated that Windows 10(64bit) Device Manager detected two COM ports correctly, and now using XDS110 Class Application/User UART port for UniFlash

Best Regards,
NK

    To be exact, I`ve put SOP0 and SOP2 on the board for flashing and also I`ve configured 115200baud, 8bit, no parity, 1bit for stop bit and no flow control for XDS110 Class Application/User UART port in device manger. But unfortunately, i did not help. Also, in my case, XDS110 Class Application/User UART is assigned to COM3, so i just filed the port as is in UniFlash Tool.

    Once resolved, but not stable. To be stable for UniFlashing, in my case, disconnecting my wired or wifi network, and do flashing and then it worked perfectly. I`m not sure why UniFlash (Not cloud version) is related to network, but actually it was a workaround for me.
