FTDI chip/drivers problem..

Moleskin Question

Apr 22, 2010 00:00

Hi everybody,

i installed some days ago the EVAL_ADAU_170x EBZ on a PC where i had previously installed and worked with a FET spectrum analyzer.

After working a little bit with the board, i connected the spectrum analyzer and the system told me that there were no driver installed for the FET.

Then, when i tried again with the evaluation board, i started to experience communication problems with the PC and i wasn't able anymore to make it work.

So, i uninstalled completely the FET stuff (drivers and everything), and re-installed the board, but the situation remains the same: not able anymore to make the PC and the board talk each other (note: if i go in to the hardwra configuration inside SigmaStudio everything seems to be ok, the label on the Eval170x block is orange, not red, but then when i link/compile/download the project the communication doesn't work).

I think that probably the problem is that both the board and the FET spectrum analyzer use the very same FTDI chip, and the drivers conflict caused some "damage" (maybe in the system registry? i don't have any idea, actually..), so now i cannot work even if i uninstalled the other device...Any suggestion????

Thank you very much in advance, and sorry if this is not the right place to post such an issue,

Matteo

Hello,

What you describe may be a conflict if both devices are using the FTDI drivers. However, if the ADAU1701 block in SigmaStudio is turning orange, then the software is recognizing that the driver is there. When you installed the USB drivers for SigmaStudio, were you sure to point Windows to the USB Drivers folder in the SigmaStudio installation folder? If you let Windows automatically search for a driver, then you may experience problems.

We are currently primarily supporting a new USB interface board (USBi) that does not use the FTDI chip. This stand-alone board is a more robust solution for USB communication from SigmaStudio to your target hardware. These boards can be ordered with part number EVAL-ADUSB2EBZ for $95. An application note describing this board can be found here.
