107 The Cross-Development Toolchain
108 -------------------------------
110 The :term:`Cross-Development Toolchain` consists
111 of a cross-compiler, cross-linker, and cross-debugger that are used to
112 develop user-space applications for targeted hardware; in addition,
113 the extensible SDK comes with built-in ``devtool``
117 cross-toolchain works with a matching target sysroot.
