Show HN: First ever FPGA CPU built using open source tools?

This is really cool. Thanks for doing this and sharing the instructions. Also note, James created the Gameduino 1 &amp; 2, which are worth checking out.<p><a href="http:&#x2F;&#x2F;excamera.com&#x2F;sphinx&#x2F;gameduino&#x2F;" rel="nofollow">http:&#x2F;&#x2F;excamera.com&#x2F;sphinx&#x2F;gameduino&#x2F;</a> <a href="http:&#x2F;&#x2F;excamera.com&#x2F;sphinx&#x2F;gameduino2&#x2F;" rel="nofollow">http:&#x2F;&#x2F;excamera.com&#x2F;sphinx&#x2F;gameduino2&#x2F;</a>

Congratulations on the First and thanks for the polished package - this is quite impressive.<p>I finally cracked open the iCE40 HX datasheet, but was stunned to see the memory block: &quot;Note the sysMEM Embedded Block RAM Memory address 0 cannot be initialized.&quot; That&#x27;s extremely awkward.

Interesting, I wonder if the hardware design of the FPGA is open as well (just to be pedantic), probably not :P
