Hi all.
I found that both Rx divercity switches have zero state for A and B control inputs. Thus both LNA and LNA-D connectors are not switched to Rx inputs of the LMS's. To proceed Rx testing I suggest to set the next fixed states in the FPGA: DIVSW1_P = 1, DIVSW1_N = 0, DIVSW2_P = 1, DIVSW2_N = 0. In this case LMS1 will be switched to LNA connector, but LMS2 to LNA-D.
Andrew Karpenkov, would you please to make this kind changes, until DIVSW will controled by host?
Best regards, Andrey Sviyazov.
Hi Andrey,
I'll do it ASAP and then send you flash image for FPGA.

That's an interesting question. Andrey Karpenkov - is there a way to control them from ZPU? Some config register?
Yes, I can add this option. I'll try to do it, and tomorrow make changes at github.

Hi all,
I added control logic for diversity switches into fpga part of project. Now you can manage them by setting the appropriate values in registers sr_divsw1 (180 0 adress in decimal) and sr_divsw2 (180 1 address in decimal). But I'm not tested this options yet. The following Monday I plan to do it. All changes are availible in akarpenkov/dual-channel branch at github repository.

Andrew, thank you! Could you send me compiled bitstreams? I'll put them to the server for download.
