Any recent news on the GPIO issue on RP2350? Will they ship updated silicon at some point? https://hackaday.com/2024/09/04/the-worsening-raspberry-pi-r... So far it seems the message from Raspberry Pi is "we documented the bug, so the issue is closed": https://github.com/raspberrypi/pico-feedback/issues/401#issu...

After this was published, RPi concluded the problem was a leakage current and updated the datasheet [1]. Roughly, a tiny trickle of electricity, about 100 microamps, flows out via the pin when it shouldn't. This can raise the voltage to around 2V unless you provide a path to drain it away. I've ordered one and am confident for anything I'd do it's not an issue. Usually any input I have is connected directly to the output of something else and that provides the path for the leakage current. If that isn't true, e.g. a button, then I'm using a pull-up and thus also not affected. Certain analog measurements could be affected, but again not if they have a low impedance (i.e. strong) source. The current is around 100 microamps so it's not stressing the source much. It's unfortunate that this is happening in the chip that so massively improved t
