minimal example fails to build

Actually, cortex-m-rtfm depends on cortex-m-rt 0.3. You are using 0.5 in your binary.

You can use https://github.com/japaric/cortex-m-rtfm/pull/87 waiting for the update.

Not sure I understand what you mean by "use #87".

I've simplified the dependendecies, and use cortex-m-rt 0.3:

[dependencies.stm32f4]
version = "0.2.3"
features = ["stm32f407", "rt"]

[dependencies.cortex-m]
version = "0.5.7"

[dependencies.cortex-m-rt]
version = "0.3"

[dependencies]
cortex-m-rtfm = "0.3.4"

[dependencies.panic-abort]
version = "0.3.0"

But still see the problem:

stm32f4 v0.2.3 depends on cortex-m-rt v0.5.

I mean you can use the branch of the pull request:

cortex-m-rtfm = { git = "https://github.com/ykomatsu/cortex-m-rtfm", branch = "update" }

Thanks so much! That approach did eventually work.

Welcome.
