: [USRP-users] [E310 RFNoC] TX RX Loopback bypassing the ARM
processor
Very glad to hear it! Could you tell me what UHD version (git hash) you're
using? I'd like to know for my own reference.

That should work.

1. yes
2. RFNo
1. yes
2. RFNoC
I refer back to a post I wrote detailing loopback in the FPGA. It doesn't
work "out of the box" but can be made to with minor modification.

If you haven't used RFNoC before you should probably take on the Getting

Hello all,
I am trying to utilize the full performance of the E310 and it seems like the
Arm processor is the bottleneck in this scenario. I know the AD9361 is wired
straight into the fpga, so it would make sense that a strictly bare metal
loopback is possible.
Is it possible to stream data
