[USRP-users] X310 Channel Command Issue

I am using version 003.008.004.

I am uncertain of what part of the code you are referring to that sets up the motherboard.

What version of UHD are you using?

We'd need to see the part of your code that sets up the motherboard, etc.

We don't have enough details to diagnose your problem.

I am having issue communicating with both channels on the X310.  I have 2 UBX-40 daughtercards installed in the x310, and am using the 10 Gig port as well as the 1 Gig port, with the intention to use one port to control one channel and the other card to control the other channel.  Also, I am working in receive only for now.

When I use "uhd_find_devices"  I get the following:

Device Address:
                Type:  x300
                Fpga:  HGS
                Serial:  30F5A3F

Device Address:
                Type:  x300
                Fpga:  HGS
                Serial:  30F5A3F

I also have the host PC ip addresses assigned correct; and

Which leads me to believe the daughtercards have 2 different IP addresses.  The problem is that if I task either 10.2 or 40.2 I only ever communicate with the RF A channel, never the B channel.

Can somebody please help me with this?

Thank you
