Mapping of target platform interfaces in HW/SW Co-Design Workflow to physical ports on Ettus E310

I am using the HW/SW co-design workflow to create an application on the SDR Ettus E310. To get started, I follow the tutorial Target QPSK Transmitter and Receiver to USRP E3xx Using HW/SW Co-Design Workflow.

As described there, I configured the baseband channels to TX1 and RX1 in step 1.3 Set Target Interface. This seems to result in an output on the physical pin TRX-B. Unfortunately, I could not find any description of the assignment of the logical ports in the HW/SW co-design workflow to the physical outputs of the E310 hardware. How do I configure the Target Platform Interfaces and the E3xx Transmitter/Receiver to use TRX-A as output and RX2-A as input?

Many thanks in advance for any assistance.

It seems to me that the configuration has to be done via the Frontend Side Filter and Antenna Switches of the E310. Is this feature supported in the HW/SW co-design workflow?

Hi Sebastian,

It is my understanding that you are working on HW/SW co-design workflow and wants to know about how to configure the Target Platform Interfaces and the E3xx Transmitter/Receiver. As of now, we don’t have the feature to map with physical switches and LED for E310.

Thanks for the info. How are the ports of the E310 connected then? Can only the TRX connectors be used? Which analog filters are active?
