FX3 questions - using full speed USB to transfer data captured via GPIF II
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!
