NetBSD/evbarm also supports some specific embedded system products based on prototype board designs. -Matt Thomas is the maintainer of NetBSD/evbarm. +### CPU types + +The evbarm port can be built with a variety of CPU options, corresponding to the +[large array of ARM CPU architectures](https://en.wikipedia.org/wiki/ARM_architecture#Cores). +There are +four main variables: the word size, the instruction set, the +endianness, and whether there is hardware floating point. By default +the CPU type is "earm", and this implies aarch32 (32-bit), earmv5 cpu +architecture, little endian (el when explicitly stated), and soft +(Emulated) floating point. Another example, suitable for Raspberry PI +2, is earmv7hf, which is aarch32, the v7 instruction set, little +endian, and hardware floating point. + +Typically, various boards are best compiled with a CPU type that +matches the board's CPU and floating point support, but generally a +lower CPU instruction set version is workable on a newer board. See +build.sh and look for aliases for the evbarm port. + +Through NetBSD 8, the evbarm port has supported exclusively the +aarch32 (32-bit CPU) sub-family of the ARM architecture. Some +processors, such as many supporting the armv8 CPU architecture, also +support a 64-bit instruction set, referred to as aarch64. This is +sometimes referred to as a distinct port, [[NetBSD/aarch64|aarch64]], +with code in src/sys/arch/aarch64, but it is built as the evbarm port +with aarch64 cpu type, and available as the alias evbarm64. + +Note that MACHINE_ARCH=aarch64 currently refers to the A64 instruction +set and the aarch64 architecture, built for the armv8 architecture. +(Note also that armv8 is the first architecture to support aarch64, so +this will not be an issue until at least armv9.) + +### anita and qemu + +anita can be used to test builds. (In addition to anita, install qemu and dtb-arm-vexpress from pkgsrc.)
