FX3 stalls on using Bit 8 and above on 16 Bit Gpif

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

Ralf

Have you tried the same in FX3 DVK?

When you say they're unused are you holding them high or low?

Is bit8 the only line causing the issue?
