1 year ago I'm not sure this is a bug specifically in IDF. The error indicates that the linker was given object files with incompatible version of RISC-V integer ISA.
esp-2021r2-patch5-8.4.0 GCC based toolchain used in IDF v4.4.x uses binutils 2.35.1, which produces this arch tag: rv32i2p0_m2p0_a2p0_f2p0_d2p0_c2p0.
Newer binutils releases produce an arch tag with a different "I" version (2.1 instead of 2.0): rv32i2p1_m2p0_c2p0_zicsr2p0_zifencei2p0.
My guess is that Rust compiler you are using also generates code with something like rv32i2p1_m2p0_c2p0, which is incompatible with object files from IDF which are built with rv32i2p0_m2p0_a2p0_f2p0_d2p0_c2p0.
Just my understanding of the issue so far. I don't yet have an idea where/how it should be fixed. As far as IDF is concerned, release/v4.4 has always been generating code with rv32i2p0, no changes have occurred.

Any idea on a work around?

1 year ago Hi All,
I thought I should share this information just in case someone might have the same issue and stumble on to this page.
After many days of trying to get the default esp-idf-template project to build. I have manage to get a simple blinky program working.
Thanks to Hutscape page that showed a work around on how to create a project that builds.
Just to re-iterate when the project is created using the recommended esp-idf-template command as below
cargo generate esp-rs/esp-idf-template cargo
The project is created successfully, but the problem occurs when you issue the command to build for example
cargo build
This command fails as indicated in my first message above. In order to create a project that will build, I found Hutscape page which used the following command
cargo generate --vcs none --git https://github.com/esp-rs/esp-idf-template cargo
Creating the project with this form allowed the project to build.
Below is the source code and Cargo.toml for the blinky program.
Cargo.toml `[package] name = "blinky" version = "0.1.0" authors = ["authors namemyemail@address.com"] edition = "2021" resolver = "2" rust-version = "1.66"

[profile.dev] debug = true # Symbols are nice and they don't increase the size on Flash opt-level = "z"
