Also, the DDR chip is much larger, and has higher memory bandwidth, so it isn't an unreasonable decision. It is just a hopefully short patch of pain while I get it all working, and then we will just ignore it. As for other options, there really aren't any other suitable FPGA boards on the market, and I don't want to go designing my own for a variety of reasons, but mostly because custom boards are expensive to make, and then the community has to wait for me to get enough orders to produce a next batch. So I will persevere.<br /><br />Paul.Paul Gardner-Stephenhttps://www.blogger.com/profile/10150903760695355706noreply@blogger.comtag:blogger.com,1999:blog-4017745189504803687.post-974970447172784492015-02-26T11:13:06.947+10:302015-02-26T11:13:06.947+10:30Sounds like they made a mess out of "upgradin...Sounds like they made a mess out of "upgrading" this board. If it's too much work, or too many compromises, it might be worth reevaluating options.Anonymousnoreply@blogger.com
