1.39      wiki        3: This page attempts to document and coordinate efforts towards NetBSD/evbarm on [Raspberry Pi](http://www.raspberrypi.org). All board variants are supported.
                      4: 
                      5: Initial Raspberry Pi support was introduced in NetBSD 6.0. NetBSD 7.0 adds complete support for the board, along with introducing support for the quad-core Raspberry Pi 2 board.

1.36      wiki       14:  - You may use the rpi.img file created by an evbarm build - evbarm-earmv6hf is recommended. This isn't optimized for Raspberry Pi 2, but allows a single image to be used for all boards.
1.38      wiki       15:    - The Raspberry Pi and Pi 2 ports will be part of the NetBSD 7 release.
1.34      wiki       16:    - The automatic nightly builds can be found in the 'evbarm-earmv6hf/binary/gzimg/' directory on [nyftp.netbsd.org](http://nyftp.netbsd.org/pub/NetBSD-daily/).
                     17:      - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
