Hello, But due to this error i figured the issue out. It seems like the rust version installed via homebrew isn't compatible. Thanks a lot! |
|
Try using release mode: |
|
➜ rust-esp32-std-demo git:(main) ✗ cargo +esp espflash /dev/tty.usbserial-0001 --release Chip type: ESP32 (revision 1) Tried that too, still too large... |
|
Is your project open source? |
|
I'm currently building the demo application: https://github.com/ivmarkov/rust-esp32-std-demo |
|
I stripped the example project down until it fitted into the available space. Again: Thanks a lot! |
Hello,
i want to get started with my esp32 using rust. Unfortunately i'm unable to build the example project.

IMPORTANT!
The following environment variables need to be updated:
export LIBCLANG_PATH="/Users/sk/.espressif/tools/xtensa-esp32-elf-clang/esp-14.0.0-20220415-aarch64-apple-darwin/lib/"
export PATH="/Users/sk/.espressif/tools/xtensa-esp32-elf-gcc/8_4_0-esp-2021r2-patch3-aarch64-apple-darwin/bin/:/Users/sk/.espressif/tools/xtensa-esp32s2-elf-gcc/8_4_0-esp-2021r2-patch3-aarch64-apple-darwin/bin/:/Users/sk/.espressif/tools/xtensa-esp32s3-elf-gcc/8_4_0-esp-2021r2-patch3-aarch64-apple-darwin/bin/:$PATH"
If you want to activate the ESP-RS environment in every terminal session automatically, you can the previous commands to "/Users/sk/.zshrc"
However, it is not recommended, as doing so activates ESP-RS virtual environment in every terminal session (including those where ESP-RS is not needed), defeating the purpose of the virtual environment and likely affecting other software.
The reccomended approach is to source the export file: ". export-esp.sh"
Note: This should be done in every terminal session.

Uncomment this and use the esp-idf-sys "native" build feature (
cargo build --features native) to build against ESP-IDF 5.0 (master)#ESP_IDF_VERSION = { value = "master" }
Comment out this when using the PlatformIO build (it only supports
v4.3.2)ESP_IDF_VERSION = { value = "release/v4.4" }
These configurations will pick up your custom "sdkconfig.release", "sdkconfig.debug" or "sdkconfig.defaults[.*]" files
that you might put in the root of the project
The easiest way to generate a full "sdkconfig" configuration (as opposed to manually enabling only the necessary flags via "sdkconfig.defaults[.*]"
is by running "cargo pio espidf menuconfig" (that is, if using the pio builder)
#ESP_IDF_SDKCONFIG = { value = "sdkconfig.release;sdkconfig.debug" }
ESP_IDF_SDKCONFIG_DEFAULTS = { value = "sdkconfig.defaults;sdkconfig.defaults.esp32;sdkconfig.defaults.esp32s2" }
Am i missing something?
