While this seems to work reliably, it solves the same issue as probe-rs/probe-rs#3429 Are there other users of flash-algo that might still need a manual reset of core 1? |

There is a world in which you might want to not reset everything, but you want to change flash with both cores halted (emulated breakpoints comes to mind), but I think that wouldn't work with the flash algo as-is, and we should wait until we have someone that needs that first. |

Debug probes usually only do a sysreset before flashing a new firmware. But on rp2040, that only resets core 0, while core 1 might continue running. Depending on the firmware, this may interfere with the flashing. (Often, core 1 will just crash when the flash gets detached from XIP, but that's not guaranteed.)
So before starting the flash algorithm, make sure that core 1 is reset as well.
