Hello again!

Well folks, it's been a few weeks since my last post. So I am posting an overall update on my hobby project(s) now..

'Ohm' board development status: Ready for a small-scale production run!

After adding numerous fixes to the PCB artwork, I believe the resultant new revision is good enough for a pilot production run!

There are sufficient (as well as cool) HDL examples for potential users to 'kick the tires' on the 'Ohm' board, so to speak. More cool examples would be nice, but those can be added later.

Only thing left to do now is wait for a reply from component suppliers and then work out the final board pricing. Good times! :-D

'Ohm+' board development status: Board tested OK but needs a 'killer' HDL application example..

Successfully tested the 128MB LPDDR RAM on the Ohm+ prototype @ 100MHz max. using CAS=2 (yay!). However, it does not meet timing at that rate nor does the test code support burst mode transfers (yet). Tweaked ram controller HDL needs more work before it will be viable for use in system application. Another (probably better and faster) alternative would be to use Lattice's own LPDDR controller IP, but apparently that is not free..

After adding numerous fixes to the PCB artwork, this board revision is also good enough IMHO for a pilot production run! Apart from RAM, it is 100% backwards compatible with the standard 'Ohm' board (which uses 32MB low-power SDRAM instead of 128MB LPDDR).

Summary: My 'Ohm' board is now ready for a small-scale production run. My 'Ohm+' PCB artwork is also ready but needs worthy working HDL examples to make it a viable platform. Therefore I will focus on taking the 'Ohm' board on to the next level, but also see what examples could be brought to Ohm+ as well as the Ohm...

Well, that's all for now. As soon as I know how much these boards will cost to make, I will post another update (hopefully soon). Watch this space! ;-)
