Hello,
I have to transfer data from FX3 to FPGA using GPIF II Interface.
here Producer Events are generating but Consumer Events are not generating.
Please find the firmware and GPIF file attached below.I need your help very badly.
Best regards,

Hello Aswini,
The issue you mentioned in FX3 to FPGA via GPIF II Interface , I tried to reproduce at my end.
I programmed the FX3 with default firmware and checked the flags before and after transfer (without reading it on GPIF side)
These are the traces i got with proper PCLK - initially low and gets high when some data is transferred. Flags C goes low again when DMA buffer is FULL
I also observed that if PCLK is not given properly these flags misbehave. Trace with flags without proper PCLK and before data transfer .
Initially before transfer both flags will be low as mentioned in state machine. So before transferring you should get both flags low.
