ADS1235EVM: PC not recognizing board

Part Number: ADS1235EVM

I've installed the main program and the device package, however the program still isn't detecting the board. I tried to flash the board with the firmware.bin file for the board definition but it erased the current firmware and then failed saying "The USB DFU Drivers are not installed!" I didn't see this driver on the TI website and when I installed the main program it said it was installing all drivers as well, so I'm not sure what's wrong. 

  • Hi Avak,

    Welcome to the TI E2E Forums!

    I'm not sure if the DFU driver is provided in either of those software packages; however, you can download it from the link provided here: This driver installer was intended for a different EVM, but the same DFU driver is used for the ADS1235EVM.

    After running unzipping the archive and running the driver installer, you will probably need to manually associate the device to the driver by opening Windows Device Manager and following the instructions provided at the above link. When selecting the driver file, select the boot_usb.inf file for the unknown device.

    Once you have had the driver installed you can attempt to flash the board again.

    If the Delta-Sigma EvaluaTIon Software is still not recognizing the EVM after that, the most likely issue is that the GUI and device package were installed under different user accounts. To resolve this problem, refer to

    I hope that helps!

  • I installed the driver from the link you had provided, however when I plug in the board, the computer still doesn't recognize it. None of the options (Tina Firmware Update device, Generic Bulk Device, Serial COM Device) appear when I plug it in. Also, I am using Windows 10.

  • Hi Avak,

    Unfortunately, installing the driver alone will not get the computer to recognize the device since it has already been plugged in. You'll need to also manually associate the device to the driver.

    Do you see any UNKNOWN devices listed in Windows Device Manager when the ADS1235EVM is plugged in?
