if you find a SoC for $1 that has 2 Ethernet ports, and a usb host on it, while also having two cores and supporting 32MB of RAM you'll surprise me. rp2350 does all of the above for $1

Have you tested out the 2x PSRAM configuration; if so, have you written anything up about it? :) I've thought about a configuration like that myself but haven't committed to any hardware yet.
yes i have tested it and no i have not written about it (yet). it does work and with the new ISSI 16MB chips, it gives 32MB of continuous memory!
Awesome - I might just have to try it.
How are you handling startup? The approach I had in mind was putting boot flash on the second channel with a separate CS pin from PSRAM and configuring that in OTP; any idea if that would work?
