Error while building with the pio feature about esp-idf-sys

[1c3t3a]

By the way: Building with the feature native runs through, but results in a malformed binary on the esp32c3:

Thanks for the report! I'll take a look at the native build issues.

For PIO, please see espressif/rust-esp32-example#42 (comment)

Ah great! The pio fix is working! If you need me to test something with the native build just ping me here ;)

Another way to fix that would be to place this sdkconfig.defaults file in the root of your binary crate.

I would strongly advise generating your project using the esp-idf-template project now. It is the absolute minimum - so to say - that you need to bootstrap a "Hello-world!" one-liner with rust on top of the ESP-IDF.
