<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> is this a Polish pope reference, again?</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> <span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> I'm currently struggling with dumping an ESMT F50-series QSPI NAND flash. flashrom doesn't support it, loading the spinand.ko module on Raspberry Pi detects the chip correctly but fails to access its contents. My suspicion is the SPI controller, so I thought about synthesizing a Cadence QSPI into a Zynq-7000 and accessing it from Petalinux.<br />I have no idea how much effort it would be to write a SPI-NAND applet for Glasgow.</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Also most of the cheap FPGA devkits don't have a MCU, and either 10/100 ethernet or USB2 as the only PC interface</p><p>Dumptruck has an RGMII PHY direct to the FPGA, plus a STM32H735 connected by a fast memory mapped interface (>500 Mbps throughput) to the FPGA.</p><p>Right now all of the dumping algorithms are software driven, as is the TCP/IP stack. over time as I build out an accelerated processing flow and move more of the datapath to FPGA I expect performance to skyrocket. There's a lot of round tripping now.</p>
<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> oh yeah that makes sense</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> It's also going to serve as a general purpose swiss-army-knife devkit for talking to random embedded stuff with a ton of IO at weird voltage levels.</p><p>The FPGA has four full 7 series IO banks broken out (200 pins, 50 each at 3.3 / 2.5 / 1.8 / 1.2) with no level shifters, just directly to a socket.</p><p>A lot of the low cost entry level devkits only have like a few PMODs, and the high end ones have expensive FMC connectors at only like one voltage level.</p><p>There was a gap for a low cost board with a ton of IO at all different voltages.</p>
