 Hi,

   

Our goal is to capture 16-bit words, using an external clock, into a FIFO, that will be read by an application over USB (eventually USB 3.0).

   

We're using the FX3 board.

   

One issue is that it seems that there is a clock signal on the PCLK line, even though we have selected an external clock in the configuration wizard that generated the .img file.

   

A second problem is that we're now getting the error:

   

 

   

"Launching Gpif2Usb.elf has encountered a problem.  Error starting process."

   

 

   

We don't know what this caused this problem to crop up -- it could have been from selecting an embedded GDB or gdbserver, but we can't get back to that menu, and don't understand the implications of this selection.

   

 

   

Thank you for any help!

   

 

   

Larry and team ...

Hi all,

   

Please ignore this request - it turns out that we resolved both problems.

   

The failure to load was resolved by recreating the Eclipse workspace.

   

The failure to set the PCLK pin to input mode was resolved by recognizing that the GPIF include file was coming from the wrong path -- not the file produced by the GPIF designer tool.

   

Sorry for the distraction!
