NetBSD/evbarm is the port of NetBSD to various systems based on chips
implementing the ARM architecture. The "evb" component is a reference
to evaluation boards, the original target of the port, but this
is no longer relevant - NetBSD/evbarm now runs on a range of
hardware based on APCI or devicetrees, including a range of development
boards, powerful servers, virtual machines, and even some laptops.
### CPU types
Various CPU variants are supported, e.g:
- evbarm-earmv6hf - ARMv6 with EABI and hardware floating point, e.g.
the original Raspberry Pi.
- evbarm-earmv7hf - ARMv7 with EABI and hardware floating point, e.g.
most recent and common 32-bit ARM boards.
- evbarm-earmv7hfeb - Same as the above, but with the CPU running in
big endian mode.
- evbarm-aarch64 - 64-bit ARMv8
- evbarm-aarch64eb - Same as the above, but with the CPU running in
big endian mode.
Since NetBSD 9.0, 64-bit ARM processors are supported (referred to here
as aarch64). These run with fully 64-bit kernels and userland. Running
32-bit ARM binaries is also supported with `compat32`.
evbarm variants are little endian unless otherwise stated. NetBSD provides
big endian images primarily for testing purposes and to ensure that the code
### armbsd.org builds
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*.
### Board specific information (often including installation information)

- [[BeagleBone, BeagleBone Black, and PocketBeagle|BeagleBone]]
- [[NVIDIA Tegra|Tegra]]
- [[ODROID C1 and C1+|ODROID-C1]]
- [[Raspberry Pi 1, 2 and 3|Raspberry Pi]]

**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.
See the [[NetBSD/evbarm under QEMU|qemu_arm]] page for instructions on how to get started with QEMU.
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.
- evbarm-earmv7hf uses "qemu-system-arm -M vexpress-a15"
- evbarm-aarch64 uses "qemu-system-aarch64 -M virt"
- Information on how to test emulated versions of other specific hardware is welcome.
