I got some resources to get knowldege of LVGL and FreeRTOS. - https://learnesp32.com/ (Concepts of FreeRTOS, task, event, queue,) - https://lvgl.academy/ (You can learn how to use LVGL with freeRTOS, but It is old version of LVGL) - https://www.udemy.com/course/iot-application-development-with-the-esp32-using-the-esp-idf/ (ESP32 But you can notice how to work task and message queue event in WiFi and webserver, littile bit complex )

The big thing is the examples they have. I use Visual Studio Code with the ESP-idf extention, and if I want to learn a new functionality, I load an example and break it down. There is also the website https://learnesp32.com, which does a very high level understanding of the code, but if you have prior experience with other micro-controllers, than that probably isn't necessary.

A previous thread recommended this course: https://learnesp32.com/

The best place is the course offered by https://learnesp32.com . It's a paid course but covers all basic and intermediate topics

And yes! LearnESP32.com by Mair is a great way to getting started. Checkout his github page for valuable info.

Then I moved on to some example apps with ESP IDF, and those compiled, flashed, and worked perfectly first try. So then I found this tutorial website, and after about a day, I was doing all sorts of fancy stuff. That was the best $50 I had spent as far as understanding all the core bits very well and knowing my way around.

When I was new to ESP32 development, I found the videos at https://learnesp32.com/ to be very valuable. I felt very comfortable with ESP IDF development afterwards. Well worth $50.

Alternatively, there's another initiative called codegen_gcc which is about using GCC as a backend for the rustc compiler. It's (much) more advanced in Rust support, but I am not sure how easy it would be to use a modified libgccjit from there.

In addition to what others have said about platform support, Rust is also on its way to gaining more platform support through rustc_codegen_gcc, the GCC codegen backend for rustc, as an alternative to the LLVM backend. That means many of the platforms GCC supports will suddenly become available with Rust.

Yeah, rustc_codegen_gcc is a GCC backend for rustc, and its making a lot of good regular progress.

gcc-rs is one of two projects for bringing Rust to gcc. gcc-rs is the more ambitious of the two, with an entirely new frontend. There is also rustc_codegen_gcc (https://github.com/rust-lang/rustc_codegen_gcc) that keeps the rustc frontend, and only swaps out LLVM for GCC at the codegen stage.

Fixing unwinding in release mode is still ungoing. I could use some help here, so anyone with some understanding of unwinding, landing pads or GCC, please come on this issue to discuss this.

Additionally, there is gcc codegen for rustc (https://github.com/rust-lang/rustc_codegen_gcc), which is not a compiler per se, but an alternative code generator, with more architectures supported and other nice things. It's also coming along, but there's still a lot of work to do there too. There's also Cranelift codegen (https://github.com/bjorn3/rustc_codegen_cranelift), which is designed to make debug builds faster, but this is not as exciting/useful as the other 2.

Good idea. I added the tag "help wanted" to the issue.

Also, there are indeed ABI issues, e.g. for 128-bit integers and NaN.

I'm excited about both the backend & the frontend.

There is also a project for rustc to use GCC instead of LLVM for codegen.
