Hi,
I'm Transfering data from FX3 to FPGA via GPIF II interface.With the Default Firmware i.e., the firmware in AN65974 application note i'm getting 0000 .But i have made some changes in GPIF II like(I made flags as active high and in transition equation i added DMA_RDY_TH3),with this i'm able to get one byte of data from FX3 to FPGA. After all these changes the signals also asserting properly from FPGA side.
My question is why the remaining bytes are missing,what may be the reason for this?
Can anyone let me know about this.
Regards,
Aswini

Hello Aswini,
Please let me know which FPGA are you working on. Application note AN 65974 has the bit file for Spartan 6 FPGA. Please confirm that you are using Xilinx Spartan 6 FPGA.
I have tried viewing the traces with default firmware. It is working fine at my end.
To debug this problem, please use the default firmware as it is (don't change the initial value of the pins). if you change the pins polarity without changing the FPGA code the application won't work.
Please follow all the steps mentioned in section 11.5.1 of the application note and let me know the results.
Regards,
Rashi
