AN65974 FX3 GPIF II 32 Bit
I am trying to manually compile the SF_loopback.img, SF_streamIN.img and SF_streamOUT.img which are included in the AN65974 project zip file provide at this link:
All the pre-compiled images seem to work fine with the FPGA statemachine that is provided. I need to change a few parameters in the images so I have recompiled the C code in eclipse, but the header in the GPIF II project that was provided is for a 16 bit interface. I changed the interface to 32 in the GPIF II project and confirmed it in the newly generated header file. When I load this version of the image onto the FX3 SuperSpeed Explorer Kit it says, "Download Successful" and then the interface disappears and will not reappear until I restart the FX3 board. If I set CY_FX_SLFIFO_GPIF_16_32BIT_CONF_SELECT equal to 0 indicating a 16 bit interface then the board loads fine. The interface remains after the image is downloaded. The problem is that I need a 32 bit interface. Is there anything I could be missing?
I just want to recompile the images manually that are provided in the AN65974 project zip file (which are 32 bit) and I cannot figure it out.
Thank you in advance.
