Linking error

[JonasFocke01]

Hello,

i have a fairly large codebase (for my standards) for the rpi pico, that i slowly want to migrate to the embassy runtime, to take advantage of async behavior. I got to a point, where everything compiles, but the linking after that fails with Linking globals named '__subsf3': symbol multiply defined. Furthermore it says, that it could not load bitcode of module rp2040_hal-08399d7ef07092cd.rp2040_hal.93c04970eac56577-cgu.10.rcgu.o. Luckily, the rp2040 crate directly is just used in one single place. commenting that out wont fix the linking problem. I suspect, that the rp2040 crate is used indirectly in many more place through the rp_pio crate or similar. I cant really test that, because its everywhere. I only opened this issue, because the README of this repo says, that this works with any other HALs out there.

Are there any tricks on how to get around this?
Do you need more info from me?

you're probably hitting this

rust-lang/rust#118609
rp-rs/rp2040-project-template#71

I only opened this issue, because the README of this repo says, that this works with any other HALs out there.

if you're using rp2040_hal and not embassy-rp then you should ask in the rp-rs project, as this is not an embassy issue.

Thank you for the hint! Digging around that resolved my issue. ❤️
