Rp2350. That’s what I’m basing my next revision of this project on



https://www.raspberrypi.com/products/rp2350/

0.5MB RAM and 4MB of flash might not sound like a lot, but that's plenty for many micro computer system environments.


It supports QSPI PSRAM natively. So it’ll be a lot faster than doing in manually on ATSAMD21


Also M33 vs M0 and higher clock - should be 2-3x faster. And maybe you can do something with the second core.

Im super impressed you got this to work! The memories of the SAMD clocks... Shudders.


I found an older HN thread from about a month ago while trying to learn more about the RP2350

It seems that it didn't get much coverage at the time.
