Insanity level: ✅ just right

Coreforge is at it again, repurposing an old AMD B350 motherboard (sans CPU) as a Raspberry Pi PCIe breakout board: https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/809

@geerlingguy you say old, I say my actual setup.
@ariedov @geerlingguy
old enough that it was 15€ on ebay (but also listed as broken, whatever is actually broken)
@coreforge "Not broken enough" 🤣 @ariedov @geerlingguy
@pa it's probably just a bad bios, and this board doesn't have a recovery flash option like newer ones do yet. There's an SPI header for it though (and the SPI pins on the socked), but I haven't even tried reading it yet, and I don't have a compatible CPU anyways
@coreforge @pa Oh hey you're on mastodon!
@geerlingguy nice hack! that's particularly clever
@geerlingguy that's... all sorts of incredible.

@geerlingguy So cool! I love this kind of projects so much!
@geerlingguy that's super cool but it makes sense! PCIe lanes are PCIe lanes, so doesn't matter if the PCIe lanes come from an AM4 CPU nestled in it's socket as designed or a Raspberry Pi via breakout cable jabbed into very specific pins in the socket
I wonder how did the team discover which pins to connect on the exposed processor interface, and how did they connect them by hand
@csolisr You can find the AM4 socket pinout with a quick web search (IIRC it's on wikichip).
@geerlingguy I can hear Wendell already.
@geerlingguy insane. amazing. insane.
