YRabbit<p>I have a feeling that I will soon figure out how to transfer the clock signal from the pin to the flip-flop in <a href="https://mastodon.sdf.org/tags/gowin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gowin</span></a> 5A-25A <a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a>🤣 <br>This series differs significantly from previous ones, if only because the pins are not direct inputs to the clock system—I come across some blocks in the route whose purpose is unclear, possibly energy-saving switches.🤔 <br>It's fun. <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a></p>

YRabbit<p>GW5 family (<a href="https://mastodon.sdf.org/tags/TangPrimer25k" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TangPrimer25k</span></a>) got support for huge LUTs in <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a>!🍾 </p><p><a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a>#sipeed#gowin</p>
YRabbit<p>Gee! Made base generation for <a href="https://mastodon.sdf.org/tags/TangPrimer25k" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TangPrimer25k</span></a> where this tricky IO layout is taken into account.</p><p><a href="https://mastodon.sdf.org/tags/nextpnr" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nextpnr</span></a> already understands that despite the fact that one and the same cell for IO is set - IOT3, the blocks A and B together with their wires are placed in different cells.</p><p>It does not work naturally - I need to set the fuses in a different cell as well 🤣 <a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a> <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a></p>
YRabbit<p>Ladies and gentlemen! The first design for the <a href="https://mastodon.sdf.org/tags/Gowin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Gowin</span></a> GW5A chip series to fully pass the whole Yosys->Nextpnr->Apicula->working-board chain!🍾 🍾 🍾 </p><p>The design itself is nothing to write home about - just an inversion of the LED button, but words won't convey what kind of creepy stuff I encountered inside the chip!</p><p>I'm allowed to rest a little over the weekend:)<br><a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a> <a href="https://mastodon.sdf.org/tags/sipeed" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sipeed</span></a> <a href="https://mastodon.sdf.org/tags/gowin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gowin</span></a> <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a></p>
YRabbit<p>M.2 USB SSD wakes up using <a href="https://mastodon.sdf.org/tags/ZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ZFS</span></a> and <a href="https://mastodon.sdf.org/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeBSD</span></a>. I'll leave that question for later (although I have SATA mechanical drives and it would be annoying to see wake-up failures).</p><p>I need the Linux command line to create <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a> bases. Qemu works here, which is welcome. But 10 times slower than under <a href="https://mastodon.sdf.org/tags/DragonFlyBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DragonFlyBSD</span></a> - accel=nvmm accelerator is used there. I wonder what kind of accelerators there are under <a href="https://mastodon.sdf.org/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeBSD</span></a>?🤔</p>
YRabbit<p>@splinedrive 's <a href="https://mastodon.sdf.org/tags/riscv" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>riscv</span></a> thing is running Linux on <a href="https://mastodon.sdf.org/tags/tangnano20k" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tangnano20k</span></a> . 🤣 But that's not the news, the news is that this is the work of a new <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a> that will allow support for the cool GW5A series <a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a>!</p>
YRabbit<p>Gee! Beat the last two chips!</p><p>This version of <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a> (with new bases) is able to create the whole set of workable examples from the kit! <br><a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a></p>
YRabbit<p>I check the firmware format with compression of both FPGA pieces and initial BSRAM content on the example of already classic two Goblins.😜 <br><a href="https://mastodon.sdf.org/tags/fpga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fpga</span></a> <a href="https://mastodon.sdf.org/tags/gowin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gowin</span></a> <a href="https://mastodon.sdf.org/tags/apicula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apicula</span></a> <a href="https://mastodon.sdf.org/tags/sipeed" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sipeed</span></a></p>
