Vedant is now working on the RiskFive board hardware. He tested the video, SPI, and Wiznet W5500. (Joerg is also working on W5500 independent of our project.) On Friday he started testing the mouse and keyboard. I think that the board can ship in about a month, after we put together the first draft of the the RISC5 firmware using the RAM and outputting black and white video. We already have Astrobe, but is working from the internal on chip BRAM while ignoring the off chip RAM.</span><br><span></span><br><span>So we too are moving forward!</span><br><span></span><br><span>Thank you,</span><br><span>Wojtek</span><br><span>--</span><br><span><a href="mailto:Oberon@lists.inf.ethz.ch">Oberon@lists.inf.ethz.ch</a> mailing list for ETH Oberon and related systems</span><br><span><a href="https://lists.inf.ethz.ch/mailman/listinfo/oberon">https://lists.inf.ethz.ch/mailman/listinfo/oberon</a></span><br></div></blockquote></div></div></body></html>
