Hi! The errros are already fixed on git, adding:

[patch.crates-io]
esp-idf-svc = { git = "https://github.com/esp-rs/esp-idf-svc" }
esp-idf-hal = { git = "https://github.com/esp-rs/esp-idf-hal" }

to your Cargo.toml should fix the issues

Actually you need all of:

[patch.crates-io]
esp-idf-svc = { git = "https://github.com/esp-rs/esp-idf-svc" }
esp-idf-hal = { git = "https://github.com/esp-rs/esp-idf-hal" }
esp-idf-sys = { git = "https://github.com/esp-rs/esp-idf-sys" }
embuild = { git = "https://github.com/esp-rs/embuild" }

Alternatively, you can downgrade your nightly to a one from ~ 2 weeks ago, and use that.
Or, just use the esp toolchain.

NOTE: We'll have a new release very soon now (as in a week if not a few days).

Yes that has worked, thanks guys for the fast replies
