Hi, Device (FX2LP) NAKs the IN requests whenever it does not have any data to send. Whenever the FPGA connected to GPIF writes some data then it will respond with that data. Otherwise, it will continuously NAK the IN requests. Coming to the timeout value, Xferdata function returns failure if it does not receive any data with in that time out value. You can change this parameter before calling Xferdata function. Thanks, sai krishna.
