Hi, Within the last couple of weeks, the N310 tree went from having 1 front end to 2 front ends per daughterboard (A,B,C, or D). What is the reason for this? Why would the user want to choose subdev spec "A0" as opposed to "A1" and same for other paths?
I attached the uhd_usrp_probe results from the most recent uhd version (2c9087d) as well as one from a couple of weeks ago (a1b5c4a) showing the difference in the trees. Rob
