Esp32 build error

[Fnux8890]

Im trying to use Embassy for an ESP32. As far as I'm aware the Embassy for ESP is based in the esp-rs tools.
When I try and build a simple startup project without any complicated bits just a hello world thing to make sure it works I get this error message

error: One of the feature flags must be provided: esp32, esp32c2, esp32c3, esp32c6, esp32h2, esp32p4, esp32s2, esp32s3,

    |
    = note: this error originates in the macro `assert_used_features` which comes from the expansion of the macro `assert_unique_used_features` (in Nightly builds, run with -Z macro-backtrace for more info)

I'm not sure how to fix this error message.
And not sure if this is an error stemming from the package or something in my project that I'm missing.

You need to specify the chip that you are targeting via a feature, in your case you'd need to use esp32 feature of esp-hal. I'd suggest joining our matrix channel (https://matrix.to/#/#esp-rs:matrix.org) for similar questions since this is not really related with espup

[Fnux8890]

okay cool.
I'm not sure what matrix is in this regard.

Are there other channels or discussion boards that are more suited for these kinda questions?

[Fnux8890]

Just to clarify.
I can see that matrix is a way to chat more generally about questions like this.

I guess what I'm asking is.
Is there some forums or discussion boards that are readily available like stack overflow but closer tied to the esp-rs project so others who have same questions can find it.

Not really, as a general rule of thumb I would suggest asking in the matrix channel and if that does not solve the question maybe open a discussion in the relevant repo.

Also, before asking, try searching the in Matrix channel and esp-rs org, just in case a similar question has already been replied.

Will do. Thank you very much for the reply 👍
