Greetings,

With the UHD 4.x and the radio being a block in the RFNOC, is there a way to 
write the signals input to the GPIO pins of a BasicRX daughterboard to the 
Ethernet payload?  I understand they can be used to control the radio, but I’d 
like to see their state in an output binary stream (such as chA.dat) on a host 
machine.

In UHD 3.9, our FPGA source was modified to accomplish this.  That source was 
significantly different as it appears to pre-date the RFNOC.  The gpio_atr 
module was a submodule instantiated under the radio module all inside the 
x300_core.  But now it appears the gpio_atr instantiation is outside of the 
rfnoc_radio_block instance.

Thank you,

Mark Gannet
