AWR1642BOOST: UniFlash Unable to Connect to COM Port

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: UNIFLASH

I am trying to flash the memory of the AWR1642BOOST to use the Demo Visualizer v3.2.0.  I can perform an SFLASH and erase the memory only once, but after I try to upload an SDK firmware version, the software fails and states "Image loading failed: Not able to connect to serial port. Recheck COM port selected and/or permissions."

I have checked the Device Manager and have confirmed that I am using the correct COM port.  I have also put the jumpers on SOP0 and SOP2 before connecting to a computer.  I have done this once and it worked, but now I can't get the software to flash the memory again.

    Hi,

    If this worked once there should not be a problem. Unless the board has been damaged.

    Are you loading the correct image?

    Can you share with us the path to the image you are trying to flash?

    thank you

    Benjamin,

    To use the mmWave Demo Visualizer, make sure to point Uniflash to this directory: C:\ti\mmwave_sdk_03_02_00_04\packages\ti\demo\xwr16xx\mmw

    Flash this file to your AWR1642BOOST: xwr16xx_mmw_demo.bin

    In Uniflash, in the "Settings & Utilities" tab, make sure you change the COM port to match the entry in Windows Device manager that says "Application/UART"

    For example, in my setup, I would make sure the COM port entry is set to "COM4". Then switch back to the "Program" tab and select "Load Image" after pointing to the binary image that I referenced above. This step will automatically erase the flash before storing the new application.

    Regards,
