I have an X310 with two UBX-160 v2 daughter cards installed. I've built a single channel GRC flow graph, using Subdev Spec of "A:0" then "B:0", to confirm that each of the daughter cards receives correctly. However, when I increase the Num Channels from 1 to 2 in GRC, and use a Subdev Spec of "A:0 B:0", I get this error:
RuntimeError: LookupError: IndexError: multi_usrp: RX channel 139784932838560 out of range for configured RX frontends
I am using GNURadio version: 3.8tech-preview-215-g7e5396b2
I am using UHD version: UHD_3.14.0.0-0-gd20a7ae2
I'm attempting to build a dual-channel satellite surrogate system. Any assistance is greatly appreciated.
Output of uhd_usrp_probe is as follows:
