An issue was raised on pico-feedback around the watchdog_get_count() never decrementing, see raspberrypi/pico-feedback#349. This was an issue with PlatformIO and the @earlephilhower Arduino core.

However, @JamesH65 mentioned that it is also present in the SDK, so raising here.

This appears to be an RP2040 erratum, which will need to be documented

This is documented in the code; happily it even works on RP2350

(note function has a new preferred name watchdog_get_time_remaining_ms()

This issue needs to be documented in other places.
Many people do not read the SDK source code.

Specifically in:

the RP2040 datasheet as an errata and additional detail in the description of the watchdog CTRL register.
online documentation hardware_watchdog
