RP2350 has a higher clock frequency. Has anyone tried to deploy it
I have already purchased Pico2 and it is currently on its way
Sorry, my English is not very good and I can only rely on translation software
Most likely an interested developer would have to update some Klipper files to establish support.
Probably only a matter of time before something pops up. OTOH, there seems to be no compelling reason that would make this somehow urgent.
I doubt it will used anywhere, because of errata: RP2350-E9 Erratum: can get "stuck" at 2V state even without pulldown · Issue #401 · raspberrypi/pico-feedback · GitHub
(I wanted to get one initially and try to port Klipper to it, just in case, but the issue above killed the reason).
It is like medium severity, you can work around it, but afaik in-place replacement of 2040 is not possible.
Maybe it will work, but UART or SPI can be tricky.
Till there are some useful boards, there is no reason to support that.
a higher clock frequency
About higher clocks, there is STM32H7, which already approaches current physical and software limits, and I doubt someone actually utilizes it.
AFAIK, RP2040 is similar to RP2350, and has 2 cores, so it can do more stuff.
For now, the second core is not used at all.
Does RP2040 currently lack something, that RP2350 can actually provide?
Another good question about it is whether it should use ARM or RISC-V?
