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.
