   17: NetBSD/evbarm is the port of NetBSD to various systems based on chips
   18: implementing the ARM architecture. The "evb" component is a reference
   19: to evaluation boards, the original target of the port, but this
   20: is no longer relevant - NetBSD/evbarm now runs on a range of
   21: hardware based on APCI or devicetrees, including a range of development
   22: boards, powerful servers, virtual machines, and even some laptops.

   26: ### CPU types
   27: 
   28: Various CPU variants are supported, e.g:
   29: 
   30: - evbarm-earmv6hf - ARMv6 with EABI and hardware floating point, e.g.
   31:   the original Raspberry Pi.
   32: - evbarm-earmv7hf - ARMv7 with EABI and hardware floating point, e.g.
   33:   most recent and common 32-bit ARM boards.
   34: - evbarm-earmv7hfeb - Same as the above, but with the CPU running in
   35:   big endian mode.
   36: - evbarm-aarch64 - 64-bit ARMv8
   37: - evbarm-aarch64eb - Same as the above, but with the CPU running in
   38:   big endian mode.
   39: 
   40: Since NetBSD 9.0, 64-bit ARM processors are supported (referred to here
   41: as aarch64). These run with fully 64-bit kernels and userland. Running
   42: 32-bit ARM binaries is also supported with `compat32`.
   43: 
   44: evbarm variants are little endian unless otherwise stated. NetBSD provides
   45: big endian images primarily for testing purposes and to ensure that the code
   46: is endian-clean.
   47: 
   48: ### armbsd.org builds
   49: 
   50: NetBSD developer Jared McNeill provides [builds of NetBSD 9 and -current for a vast variety of hardware.](https://www.armbsd.org/)   In addition to the standard build, these images have board-specific U-Boot contents.  See also /usr/pkgsrc/sysutils/u-boot*.
   51: 
   52: ### Board specific information (often including installation information)
   53: 
   54:  - [[Allwinner sunxi family SoCs|Allwinner]]
   55:  - [[BeagleBone, BeagleBone Black, and PocketBeagle|BeagleBone]]
   56:  - [[NVIDIA Tegra|Tegra]]
   57:  - [[ODROID C1 and C1+|ODROID-C1]]
   58:  - [[Raspberry Pi 1, 2 and 3|Raspberry Pi]]
   59:  - [[RockChip SoCs|RockChip]]
   60:  - [[Terasic DE0 Nano-SoC|Cyclone5]]
   61: 
   62: **NOTE**: This list is incomplete. For a full list of supported boards, please see the list of [32-bit](https://github.com/NetBSD/src/blob/netbsd-9/sys/arch/evbarm/conf/GENERIC#L18) and [64-bit](https://github.com/NetBSD/src/blob/netbsd-9/sys/arch/evbarm/conf/GENERIC64#L20) device trees.
   63: 
   64: ### QEMU
   65: 
   66: See the [[NetBSD/evbarm under QEMU|qemu_arm]] page for instructions on how to get started with QEMU.
   67: 
   68: ### anita
   69: 
   70: anita can be used to test builds.  (In addition to anita, install qemu and dtb-arm-vexpress from pkgsrc.)   The release subdirectory should follow the naming convention on the autobuild cluster, used below.
   71: 
   72:  - evbarm-earmv7hf uses "qemu-system-arm -M vexpress-a15"
   73:  - evbarm-aarch64 uses "qemu-system-aarch64 -M virt"
   74:  - Information on how to test emulated versions of other specific hardware is welcome.
