====== FreeBSD on the Raspberry Pi 3 (RPI3) ======

===== TODO =====

:!: these entries may be stale as of 20200202

  - wifi support (no one assigned, dependent on SDIO support)
  - bluetooth support (no one assigned)

===== Package Repo =====

Use the standard repos for %%FreeBSD%%-12 and 13-CURRENT.

If you want to build your own ports or packagesL if you're building directly on the RPI3, you will definitely want to use either USB storage or NFS. Building on the sdcard will likely wear the sdcard out.

====== Building ======

===== Prerequisites =====

[[https://github.com/freebsd/crochet|Crochet]] now supports building images for the RPI3. There's no more need for the custom build procedures. Use the GENERIC-UP arm64 kernel config.

Plop in the sdcard to the RPI3, attach the serial cable, and watch awesomeness happen.
