Building

When building the first time, fetch the submodules using

git submodule update --init --recursive

Afterwards, you can build the project using

./build.sh [--chip <chip> (default: esp32)] [--release] [--package <package> (default: app)] [--example <example>] [--flash-baudrate <baud> (default: 460800)] [--erase-flash]

For example, you can build the main example application in debug mode using

./build

or the thread_local example in release mode using

./build --release --example thread_local
