IWR6843ISK: Problems flashing the MMWAVEICBOOST with IWR6843ISK

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST, , UNIFLASH, IWR6843

Dear support Team,

we have the Board MMWAVEICBOOST in combination with the IWR6843ISK. We've been using the 3D people counting 68XX-Demo application from the industrial toolbox. So far we had always managed to flash the device, but after downgrading the software version as specified in XDS110_firmware_downgrade.pdf from the user's guide, we haven't been able to flash the device anymore. Even after trying a different binary. 

We also followed the steps as recommended in other cases,

  1. Please make sure that you have set the right SOP jumper (SOP0 and SOP2) on EVM in order to put the device in flashing mode. Do the power cycle after putting the jumpers then start using Uniflash.
  2. Make sure the COM port number is correct in the Uniflash ‘Settings & utilities’ TAB. This COM port should be the number which is populated as a “XDS110 Class Application/User UART”.
  3. Disconnect and connect the USB cable if Uniflash is not able to access the COM port.
  4. Check the power supply if it is according to the spec. (5V ~3A)
  5. If Uniflash was crashed or closed forcefully in the last session then try to close these processes from TaskManager – “DSLite.exe” and “Python**” and restart the Uniflash GUI. 
  6. Try a different PC to use the Uniflash. (if above doesn’t resolve the issue.

but it still doesn't work. We also tried pushing the reset button of the board and disconnected the PC from the network. We only started Uniflash and didn't have anything else running  in the background. See pictures below.

We would be grateful for any help on this matter.

Thank you very much.

    Hello,

    we wanted to add that we used the image from this path C:\ti\mmwave_industrial_toolbox_4_5_1\labs\people_counting\68xx_3D_people_counting\prebuilt_binaries

    regards Marco

    Hello Marco,

    The firmware downgrade requirement seems to have been fixed, as of our current testing. If you upgrade the firmware to the most recent release will the flashing work again? If you were able to flash the binary files before the downgrade and haven't changed any settings, it is also possible something went wrong with the downgrade process. Please try it with the most recent sw and let us know if you still see issues.

    See this thread for more info.

    Regards,

    Hey jackson,

    So we tried to upgrade our firmware the same way as we downgraded it:

    1. Got to the XDS Emulation Software (EMUPack) Download page and download version `9.2.0.00002` (only 32-bit version available for this release but it is compatible with 64-bit Windows).
    2. Run the installer ti_emupack_setup_9.2.0.00002_win_64.exe
    3. Select an installation directory (e.g. C:\ti) when prompted and complete the installation.
    4. Connect the MMWAVEICBOOST EVM with the IWR6843ISK module mounted on it to the PC using the XDS110 USB port.
    5. Opena command prompt in the following directory
    a. <install_path>/ccs_base/common/uscif/xds110
    6. Issue the following commands to install the firmware on your XDS110
    a. xdsdfu –m
    b. xdsdfu –f firmware.bin –r

    But when we check the firmware is it still the version 2.3.0.18 ... What are we doing wrond? Is there an easier way to do this maybe?

    Regars,

    Sven

    Hello Sven,

    It seems with the install of the XDS tools 9.2, the correct binary file is named 'firmware_3.0.0.1.3.bin'. This should be installed in the same /xds110 folder as before. Please try loading this file with the command 'xdsdfu -f firmware_3.0.0.1.3.bin -r'. This should install the new firmware.

    However, this firmware version shouldn't prevent you from flashing the sensor image. It seems the COM port might need to be reset. If the firmware upgrade doesn't help, please try the following.

    1. Close Uniflash

    2. disconnect power and USB from the ICBOOST PCB

    3. Set the jumpers for flashing mode

    4. Connect the barrel jack power to the ICBOOST

    5. Connect the USB cable to the ICBOOST

    6. Open uniflash and setup for IWR6843.

    7.Set the com port and try flashing. 

    The power and USB cable sometimes need to be reset between flashes in a specific order. Hopefully this works.

    Cheers,

    Jackson

    Hey Jackson,

    the new firmware did the Job! We can flash our board again!

    Just a little addition to your post, for other users who have the same problem. The file name is 3.0.0.13.bin

    Regards,

    Sven

    Great! Thanks for the correction. In future releases of the XDS firmware, that filename may change, so it is probably best to go look in the folder for the correct name if upgrading.

    Cheers,
