Bertl added a comment to T731: Bidirectional Packet Protocol for FPGA communication.

The main focus will be on I2C, SPI and GPIO signals, where the latter ones should have predictable delays because they might control timing sensitive signals (exposure control, trigger, etc). There is no need to handle large bandwidth or complex communication like AMBA here.

@RexOr Note that the symbol you are using as 'beta' is most likely an sz ligature (or sharp s) and not a greek beta as the beta does not have a serif or swash at the bottom while the long s from sz has.

Note that we are using Eagle 7.7.0 which is basically the last offline/old-license version before Autodesk took over.
Also note that our long term plan includes switching to KiCad which has made great progress since it gets the CERN treatment.

Bertl added a comment to T222: Low Resolution Real-time Preview Video Stream - FPGA feature.

Sounds nice and should be doable on the MicroZed.
It might be worth using decimation and keeping the framerate to avoid extensive buffering.
The obvious drawback is that connectivity via ethernet is lost.

Bertl added a comment to T731: Bidirectional Packet Protocol for FPGA communication.

The implementation has to be done on both FPGAs (Xilinx ZYNQ and Lattice MachXO2).
As this is a FOSS/OH project, you have to limit the design to IP without restrictions on both sides.
Using platform specific primitives like DDR I/O, SerDes or FIFOs is not as problem, as long as they are variants to a generic entity (which can be adapted to a new platform with little to none effort).

Bertl added a comment to M5: PCB Test.

It looks to me like the CI palette features a number of similar pastel colours, so that would work without changing the colour tone on the boards too much. E.g. secondary set, third colour (the red) and ternary set, the last two colours should be almost perfect for the MicroZed and OSHpark boards. The plugins could use the green from the secondary or ternary set, whatever looks better.

Bi-directional communication between ZYNQ and MachXO2 over a single LVDS pair (half duplex) in one case and over two LVDS pairs (full-duplex) in the other case.
Note that there is also a single ended clock line which can (and probably should :) be used for synchronization.

I don't think that this needs to be Vendor specific in any way.
I.e. you can use the Xilinx Vivado toolchain or any other (Altera Quartus, Lattice Diamond, ...) for testing and simulation, but the resulting HDL should be vendor independent.

Yes, the grey version looks really nice, so if the color version had the same lightness (or maybe a tad bit brighter) it would be almost perfect :)
