• ESP32-C2:
  1. Uncomment the ESP32-C2 section, under target.riscv32imc-unknown-none-elf.dev-dependencies of the Cargo-toml file.
  2. Run the example:
     • cargo "+nightly" run --example demo --features esp32c2 --target riscv32imc-unknown-none-elf
     • cargo "+nightly" run --example low_level --features "esp32c2,low-level" --target riscv32imc-unknown-none-elf
• ESP32-C3:
  1. Uncomment the ESP32-C3 section, under target.riscv32imc-unknown-none-elf.dev-dependencies of the Cargo-toml file.
  2. Run the example:

     • cargo "+nightly" run --example low_level --features "esp32c3,low-level" --target riscv32imc-unknown-none-elf
• ESP32-C6:
  1. Uncomment the ESP32-C6 section, under target.riscv32imac-unknown-none-elf.dev-dependencies of the Cargo-toml file.
  2. Run the example:
     • cargo "+nightly" run --example demo --features esp32c6 --target riscv32imac-unknown-none-elf
     • cargo "+nightly" run --example low_level --features "esp32c6,low-level" --target riscv32imac-unknown-none-elf
• ESP32-H2:
  1. Uncomment the ESP32-H2 section, under target.riscv32imac-unknown-none-elf.dev-dependencies of the Cargo-toml file.
  2. Run the example:
     • cargo "+nightly" run --example demo --features esp32h2 --target riscv32imac-unknown-none-elf
     • cargo "+nightly" run --example low_level --features "esp32h2,low-level" --target riscv32imac-unknown-none-elf
• ESP32-S2:
  1. Run the example:
     • cargo "+esp" run --example demo --features esp32s2 --target xtensa-esp32s2-none-elf
     • cargo +esp run --release --example low_level --features "esp32s2,low-level" --target xtensa-esp32s2-none-elf
• ESP32-S3:
  1. Run the example:
     • cargo "+esp" run --example demo --features esp32s3 --target xtensa-esp32s3-none-elf
     • cargo +esp run --release --example low_level --features "esp32s3,low-level" --target xtensa-esp32s3-none-elf

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
