> The newly released RP2350 microcontroller has a confirmed new bug in the current A2 stepping, affecting GPIO pull-down behavior.. Presumably there will be a Bx stepping at some point, but for now it is clear that the RP2350’s A2 stepping is probably best avoided.
Latest investigation shows it has nothing to do with internal pull-downs. Merely switching IO to input is enough to latch up. RP2350 doesnt work with high impedance sources.
So it seems it's an annoyance rather than a killer. A revised chip would be nice though.
Too bad hard blocks like that are almost certainly wrapped in so much NDA that we won't hear outside of of bars adjacent to conferences even if rpi wants to tell us.
