   16: NetBSD/evbarm is the port of NetBSD to various systems based on chips
   17: implementing the ARM architecture. The "evb" component is a reference
   18: to evaluation boards, the original target of the port. However, the
   19: single GENERIC/GENERIC64 kernel now supports a range of machines including
   20: development boards, virtual machines, "ServerReady" (SBBR/SBSA) hardware,
   21: and laptops through both device tree and ACPI based booting.  [Friendly image downloads](http://www.armbsd.org/arm/)

   27: ### CPU types
   28: 
   29: Various CPU variants are supported, e.g:
   30: 
   31: - evbarm-earmv6hf - ARMv6-A with EABI and hardware floating point, e.g.
   32:   the original Raspberry Pi.
   33: - evbarm-earmv7hf - ARMv7-A with EABI and hardware floating point, e.g.
   34:   most recent and common 32-bit ARM boards.
   35: - evbarm-earmv7hfeb - Same as the above, but with the CPU running in
   36:   big endian mode.
   37: - evbarm-aarch64 - 64-bit ARMv8-A boards.
   38: - evbarm-aarch64eb - Same as the above, but with the CPU running in
   39:   big endian mode.
   40: 
   41: Since NetBSD 9.0, 64-bit ARM processors are supported (referred to here
   42: as aarch64). These run with fully 64-bit kernels and userland. Running
   43: 32-bit ARM binaries is also supported with `compat32`. The 64-bit
   44: kernel supports up to 256 CPUs and the 32-bit kernel supports up to 8.
   45: 
   46: Since NetBSD 9.0, there is support for symmetric and asymmetrical
   47: multiprocessing (aka big.LITTLE).
   48: 
   49: evbarm variants are little endian unless otherwise stated. NetBSD provides
   50: big endian images primarily for testing purposes and to ensure that the code
   51: is endian-clean.

   64: **NOTE**: This list is incomplete. For a full list of supported device tree
   65: based boards, please see the list of
   66: [32-bit](https://github.com/NetBSD/src/blob/netbsd-9/sys/arch/evbarm/conf/GENERIC#L18) and
   67: [64-bit](https://github.com/NetBSD/src/blob/netbsd-9/sys/arch/evbarm/conf/GENERIC64#L20) device trees.

   69: ### QEMU
   70: 
   71: See the [[NetBSD/evbarm under QEMU|qemu_arm]] page for instructions on how to get started with QEMU.

   74: ### armbsd.org builds
   75: 
   76: NetBSD developer Jared McNeill provides [builds of NetBSD 9 and -current for a vast variety of hardware.](http://www.armbsd.org/arm/)   In addition to the standard build, these images have board-specific U-Boot contents.  See also /usr/pkgsrc/sysutils/u-boot*.
   77: 
   78: ### SSH configuration
   79: 
   80: The default configuration will connect to the local network via DHCP and
   81: run an SSH server.
   82: In order to use the SSH server, we must configure users.
   83: This can be done by writing to the SD card's MS-DOS partition.
   84: 
   85: Create a creds.txt file and use:
   86: 
   87:            useradd user password
   88: 
   89: See [creds_msdos(8)](https://man.NetBSD.org/creds_msdos.8) for
   90: additional configuration options.
   91: 
   92: ### anita
   93: 
   94: 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.
   95: 
   96:  - evbarm-earmv7hf uses 'qemu-system-arm -M vexpress-a15'
   97:  - evbarm-aarch64 uses 'qemu-system-aarch64 -M virt'
   98:  - Information on how to test emulated versions of other specific hardware is welcome.
