Building the Example

Using build script

The simplest way to build is using the provided build script:

# Build for all supported targets
./build.sh all

# Or specify a different target
./build.sh esp8266

# Or to clean all built files
./build.sh clean

Manual Build

1. Create and enter build directory:

cd example
mkdir -p build && cd build

2. Configure CMake with your ESP target:

cmake -DESP_TARGET=esp32 .. # Replace esp32 with your target (esp32s2, etc.)

3. Build the project:

cmake --build .

Build Outputs

After a successful build, you'll find:

• build/stub_<target>.elf - The compiled binary
• build/stub_<target>.map - Memory map file
• build/stub_<target>.asm - Disassembly output

Notes

• Make sure you have exported the esp-idf environment with the correct toolchain for your target ESP chip. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html
• The ESP8266 toolchain is older than the others. ./build.sh esp8266 will handle installing it.
• The example assumes the parent directory contains the ESP stub library
