    the problem of GAL(U2) not programed on the cy3684 board

    xu.zhitao

      Hi,

         

      I encountered a problem when I using the cy3684 development board. The problem is that: When I inserted the GAL(U2) into the board, PC could not recognize the board; while everything is OK, when I took out the GAL from cy3684 board. I tried 3 GALs on the board, but neither of them is OK.

         

      For the above-mentioned facts, I did not program the GAL.

         

      My question is that should i program the GAL if i want PC to recognize the board?

         

      Furthermore, if i want to develop a USB device with FPGA and cy7c68013a, should i program the FPGA before connecting the USB device to PC, so that PC can recognize the USB device?

         

      Thank you.
