Compilation Fails on Nightly

[TroyNeubauer]

I'm trying to use this library as a dependency for an embedded project. Due to limitations in other libraries I have to compile on nightly. This works fine for version 0.11

git clone https://github.com/stm32-rs/stm32f4xx-hal.git
cd stm32f4xx-hal
git checkout v0.11.0
cargo check --features=stm32f479,usb_fs,sdio-host,can,i2s,fsmc_lcd --examples

While on 0.13:

git checkout v0.13.0
cargo check --features=stm32f479,usb_fs,sdio-host,can,i2s,fsmc_lcd --examples

It fails to compile

error: could not compile `stm32f4xx-hal` due to 5 previous errors

I took the features to check with from the command in command in the CI workflow. The v0.11 features are different because some of them have been added since.

This is a major issue for me, since I depend on features added since 0.11.

Here is the code for that project if you are interested in building it: https://github.com/ERFSEDS/novafc-software/tree/131036b44ed766a1066dce81adf6f2566861a6f5/flight

Please let me know what I can do about this

[burrbull]

It's due to new embedded-hal alpha release. My fault. Need to change version = "1.0.0-alpha.7" on version = "=1.0.0-alpha.7"

[dbrgn]

I think this affects both 0.12 and 0.13.

Workaround in downstream projects:

cargo update -p embedded-hal:1.0.0-alpha.8 --precise 1.0.0-alpha.7
