Hi Alex,

I know that Ettus Research is aware of this and it's being looked at as a
possible feature. In the current version of UHD, you still have to make
manual changes to the FPGA to access the GPIO from RFNoC. The changes
aren't particularly difficult, but it can be intimidating if you're not
familiar with FPGA code or RFnoC. It basically involves following the
DIOA_FPGA and/or DIOB_FPGA signals through the design and disconnecting
them cleanly from the normal logic, and then reconnecting them to the RFNoC
image.

Thanks,

Wade
