esp-storage

This implements embedded-storage traits to access unencrypted ESP32 flash.

Current support

ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6 and ESP32-H2 are supported in esp-storage

Run examples

cargo "+esp" run --example demo --features esp32 --target xtensa-esp32-none-elf --release

cargo "+esp" run --example demo --features esp32s2 --target xtensa-esp32s2-none-elf

cargo "+esp" run --example demo --features esp32s3 --target xtensa-esp32s3-none-elf

cargo "+nightly" run --example demo --features esp32c3 --target riscv32imc-unknown-none-elf

cargo "+nightly" run --example demo --features esp32c6 --target riscv32imac-unknown-none-elf

To run the example for ESP32-C2 you need to modify Cargo-toml, section target.riscv32imc-unknown-none-elf.dev-dependencies like this:

toml esp32c2-hal = { version = "0.5.1" } esp-println = { version = "0.4.0", features = [ "esp32c2" ] } esp-backtrace = { version = "0.6.0", features = [ "esp32c2", "panic-handler", "exception-handler", "print-uart"] }

Similar changes are needed for the section target.riscv32imc-unknown-none-elf.dev-dependencies when running the demo for ESP32-H2.

Important

For ESP32 it is necessary to build with optimization level 2 or 3.

To make it work also for debug builds add this to your Cargo.toml

toml [profile.dev.package.esp-storage] opt-level = 3
