Hi, you're right, those bindings are missing. However, I don't believe you will be able to increase the throughput to 10 Msps on the E310. The interface is simply not very fast.
Since you're able to build bitfiles, I would suggest trying to build a bitfile with a DRAM (capture/replay) block. You could upload your square wave (or any other wave) and play it in a loop. Then you can stream at any bandwidth up to the E310's max of 61.44Msps. Remove all other blocks from the design (only keep radio and DRAM). Hope this helps, --M On Mon, May 5, 2025 at 6:19 PM <kurz.re...@gmail.com> wrote: > Hello All, > > I’m spinning my wheels on this and could use a clear cut answer. > > I have GNU Radio 3.10.9.2 and get the following when i do > “uhd_find_devices” command “linux; GNU C++ version 13.3.0; Boost_108300; > UHD_4.8.0.0-266-g50967d13” > > I finally got an FPGA to build with the axi_ram_fifo.yml (i customized it > for my *E310*).
