The micro USB Driver for spartan 6 lx9 microboard missing?

Hi,

I am using ISE 14.7, and Spartan 6 lx9 microboard. ISE is incapable of the CP2102 USB_UART that is supplied with the board. "Cable Auto Connect" in ISE iMPACT cannot find the cable. My windows XP, upon connecting the above USB, complains that it cannot find the driver for the cable. It is claimed that 14.7 should come with pre-installed driver for this and I should not have to do anything in this regard manually. That is not correct!.

At any rate, running the Digilent installer has not helped either (the installer could be found under C:\Xilinx\14.7\ISE_DS\common\bin\nt\digilent).

I have also followed every step of the http://www.eeworld.com.cn/uploadfile/Xilinx/uploadfile/201107/20110712022930875.pdf without any success.

I then downloaded the driver directy from Silicon Lab http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx, but again the same issue and even worse:

1- The USB port is shown as a COM port

2- ISE still cannot find it

3- Worst is the fact that no matter what you do, the driver cannot be removed (so I had to resort to a system back up!)

 

Any suggestion or recommendation is greatly appreciated.

Have you downloaded the documentation that Avnet provides? Go to http://www.em.avnet.com/s6microboard, then click on Support Files & Downloads (login is required).

 

The CP2102 is a USB-to-UART bridge, not a USB-to-JTAG bridge. It is not intended to function with the Xilinx tools. It should show up as a COM port. What you are seeing is correct functionality.

 

The Type A connector on the MicroBoard is the USB-to-JTAG bridge. Try plugging that one in and see what you see. Alternatively, you can plug a JTAG pod directly into the J6 socket on the back.
