Rust embedded standard library (std) target is not supported

[blue-freedom-technologies]

Good afternoon,

We are trying to use the subxt in a ESP32

But is giving this error:

We have also this crate in our cargo.toml getrandom = { version = "0.2", features = ["js"] }

Could you guys point us in the right path.

Cheers,

[jsdw]

Ooh interesting!

The "js" feature wouldn't work (it expects a JavaScript/wasm based env).

Possibly you need to write a custom getrandom impl to work on that target as per this doc:

https://docs.rs/getrandom/latest/getrandom/#custom-implementations

Further up the document there was talk of defining a fallback, so perhaps you can also tell it to use one of the known sources or randomness more simply, too. Id have to experiment!

[blue-freedom-technologies]

That was what we were afraid of.

thanks.

We all at Blue Freedom are big fans of your work by the way.

Cheers,

If you get it working, I'd love to see what the approach ends up being; it may be something worth either adding to our docs, or adding into the library itself behind a cfg(target)! For that reason I'll re-open this for now if that's ok!

[blue-freedom-technologies]

Hello, Not a problem.

Our architecture target is:"riscv32imac-esp-espidf"

For the getrandom library we need to use the esp_fill_random

In the getrandom this is in here espidf.rs

[target.'cfg(target_os = "espidf")'.dependencies]
getrandom = { git = "https://github.com/rust-random/getrandom.git" }

But as soon as we add the subxt library the cc compiler complaints and fails.

We have the test-app code in here.

warning: build failed, waiting for other jobs to finish...

The "Wasmtime currently doesn't support any 32bit architectures" and our target is "riscv32imac-esp-espidf".

We are trying to dig more into this error and see options going forward.

Cheers,

Ah that's interesting, thanks for the info!

Subxt itself doesnt have any dependency on wasmtime-runtime unless the "substrate-compat" features is enabled. If it is, I'd recommend disabling it and seeing whether that helps! (subxt-signer was made in part to avoid needing to pull in those dependencies and allow Subxt to compile to WASM, for instance, so it might be a similar problem here)

[blue-freedom-technologies]

Hi,

just updating. We were able to put it working.

subxt = { version = "0.31.0", default-features = false, features = ["native","unstable-metadata"] }

Today we are going to test with other boards and with heavy work rates.

Cheers,

[jsdw]

Perfect! I wonder whether you've tried 0.32.1, which is our latest version now and hopefully should work the same!

[blue-freedom-technologies]

Hi,

For the subxt-signer library

subxt-signer = { version = "0.32.1", default-features = false, features = ["sr25519","subxt"] }

When using this

let uri = SecretUri::from_str(DEVICE_ACCOUNT_SEEDS).expect("valid URI");

we are having this error:

Normaly this means that we are adressing the worng memory adress(aka: heap memory is corrupted.).

We are trying to dig more into this error and see options going forward.

Hi,

Just updating.

The line of code-> "let uri = SecretUri::from_str(DEVICE_ACCOUNT_SEEDS).expect("valid URI");"

The gdb-multiarch view

It blows up exactly in here

For the esp32c6 chip.

Cheers,

Ok sorry to hear, it's not much we can do about it unfortunately in subxt.

I assume it's invalid memory access that's happening here and it's probably a rustc bug or a bug in the OS/HAL you are using (assuming that you are not running bare-metal)

Can you please open an issue in appropriate repo? As it's a third-party crate that is causing this issue.

Hi,

we were just updating. A bug issue for the rust-lang crate was already created.

You can close the issue if you like.

Hi,

We were able to solve the issue wrapping-up the code with a thread of 32K.

We now have the necessary three boards(Were the subxt library was tested) to qualify this library good for use in our project.

I am closing this issue.

Thank you all for your help.

Cheers
