        Hi, all,I am debugging GPIF FIFO read. I use the GPIF designer to generate the file gpif.c. I only use one waveform—FIFO Read. Other waveforms are not edited. Figure below is the waveform of FIFO Read. But after I added the gpif.c into project, called the GpifInit() in TD_Init(), without other code to trigger the GPIF, the firmware doesn’t respond to Cyconnsole.exe. so what’s the matter?
