My Gpif (16 Bit and only SPI) and the Firmware running fine, as long I do not Using Bit 8 an higher.

   

If there is any Change on these Bits above, (Debugger is running), any thing from "USB RESET" or "UNKWON SETUP" Requests in various ways is happen.

   

Sometimes the FX3 make a full Reset (so I can Reload it in Control Center). I build 3 Boards, and all do the same, but in different manner.

   

Any Help ?

   

 

   

Best Regards
