TM4C123GH6ZRB: Stellaris Device Firmware Upgrade Driver on Windows 10 iot

Part Number: TM4C123GH6ZRB

Using the same method used from this post:

https://e2e.ti.com/support/microcontrollers/other/f/908/p/480438/2278292#pi320995filter=answers&pi320995scroll=false

But on a windows 10 IoT device. As soon as the device gets put into DFU mode, Windows 10 IoT cannot find a driver for it. It gets listed under other as a "Stellaris Device Firmware Upgrade" and I have not found a way to get it to be recognized. Is there a known issue or work around for this?

Thanks in advance,

John Collins

    Hi,

      I'm not clear with your problem. If you are seeing Stellaris Device Firmware Upgrade (DFU) then it is getting enumerated by your machine. When you said Window 10 IoT, I assume you are referring to a Windows 10 PC, correct?

      Below is what I see when I put the device in DFU mode. 

    My understanding is thta the device driver is installed when the DFU device is first placed on the host’s USB bus. If you need to manually install the driver then the device driver can be found in the <TivaWare_Installation>/windows_drivers directory of a TivaWare software installation.

    If I use dfuprog tool (running on the Windows 10 side) I can see two USB devices: a DFU device and a ICDI device. I can use the dfuprog.exe to download new code to the MCU.

    I can see the in Device manager before using dfu_prog to place it into DFU mode. After the device is in DFU mode, it shows up under "Other" in the Device Manager (i.e. no drivers were found). dfu_prog cannot see the device either if the drivers are not installing - no firmware can be updated and I have to power cycle the board.

    This is on Windows 10 IoT. I can use the same board/firmware/drivers on Windows 10 without issues. That is why I am asking if there are any known issues on windows 10 IoT with this.

    Regards,

    Hello John,

    This is not a known issue, you are the first to raise any topic regarding Windows 10 IoT with our team.

    We have not tested these devices on Windows 10 IoT, and right now I do not believe we would be able to do so easily. From what I read, the drivers should function the same. Are you able to try and manually install the drivers and did you try and latest drivers from: http://software-dl.ti.com/tiva-c/SW-TM4C/latest/exports/SW-TM4C-2.1.4.178.PATCH-1.0.zip?
