armnoneeabi
Arm-none-eabi refers to a GNU toolchain target used to build software for ARM microcontrollers in a bare-metal (no operating system) environment. The name expands to ARM None EABI, indicating that the code runs on ARM cores without an OS and uses the ARM Embedded Application Binary Interface. The toolchain typically includes the GNU Compiler Collection (gcc/g++), assembler, linker, and binary utilities, often together with a C runtime such as newlib. Programs compiled for arm-none-eabi are produced as ELF executables suitable for loading into microcontroller flash memory; they generally do not use dynamic libraries or the standard Linux system calls.
The target supports a range of ARM cores, with emphasis on the Cortex-M family used in embedded
Usage and ecosystem: arm-none-eabi is the standard cross-compilation target for bare-metal ARM development. It is widely
