Add LEGO Mindstorms EV3 support (Debian Buster, ARMv5TE)
Summary
ev3as a community-contributed platform target inextras/library_generation/library_generation.shextras/library_generation/ev3_toolchain.cmakefor cross-compilation to ARMv5TE (ev3dev Debian Buster)The EV3 brick runs ev3dev (Debian Buster) on an ARM926EJ-S core (ARMv5TE, soft-float). The toolchain file configures the
arm-linux-gnueabicross-compiler with the appropriate flags (-march=armv5te -mtune=arm926ej-s -mfloat-abi=soft).The build produces a static library (
libmicroros.a) that is linked at compile time against the user application — the simplest integration approach found for this platform.Full usage instructions and examples are available in the companion repository: https://github.com/racarla96/micro_ros_ev3
