//! This build script copies the `memory.x` file from the crate root into
|
|
|
|
//! a directory where the linker can always find it at build time.
|
|
|
|
//! For many projects this is optional, as the linker always searches the
|
|
|
|
//! project root directory -- wherever `Cargo.toml` is. However, if you
|
|
|
|
//! are using a workspace or have a more complicated build setup, this
|
|
|
|
//! build script becomes required. Additionally, by requesting that
|
|
|
|
//! Cargo re-run the build script whenever `memory.x` is changed,
|
|
|
|
//! updating `memory.x` ensures a rebuild of the application with the
|
|
|
|
//! new memory settings.
