Hi there,
as might have noticed, nature brothers updated their website.
-----------------------------------------------
Some good news: :)
So far the first SV rev2 prototype that we have tested has worked 100%.
We are now using it daily, with full DVI and VGA functionality, which
also proves that the DDR2 memory system works fine too. We had replaced
the old DDR2-667 chips with DDR2-800 chips because of cost and availability,
so that was a bit scary before testing. The DDR2 RAM is still only run at
185MHz (DDR370) because of FPGA limitations. We might be able to go up a
few MHz later though.
One of the new Svethlanas is being used for networking, and that works
fine too with its new 45-pin FPC cable and connector. This replaced the
old 1.27mm pitch connector and cable because of the cost of the cable.
The new motherboard clock connector on the SV rev2 has been tested by feeding
the 25.175MHz VGA clock from the soldering points just right of the large
motherboard capacitor, and then verified that the SV rev2 chooses that clock
for VGA Videl resolutions.
So right now it seems very likely that we can tell the manufacturer to go on
and make the remaining SV rev 2 boards on January 7th when they start again.
Happy New Year! :)
