I'm experimenting with running FreeBSD on a BeagleBone Black (revision C).

See also my BeagleBone Black notes.

Initial installation

  1. Get a compressed snapshot (.img.xz file) from FreeBSD's ARMv6 snapshots on ftp.freebsd.org. At the beginning of July 2015, when the latest production version was 10.1-RELEASE, I first tried a 10.1 snapshot. However, it was unable to fully boot and mount the root file system. I asked about it on Freenode IRC (channel #freebsd-embedded) and was advised that 11-CURRENT was the better choice for ARM support, at the moment. Indeed, the June 30th 11.0-CURRENT snapshot works like a charm...except for networking. They said 10.2-STABLE should be usable in the next snapshot. I put it off until September and used the Sep. 3rd snapshot of 10.2, which worked fine.
  1. Uncompress it (e.g., with 7-Zip).
  2. Use a disk image writing program (e.g. Win32DiskImager, or 'dd' on BSD/Linux) to write the image to a micro SD card. I use a 64 GB card via a USB adapter in my PC.
  3. With power off, insert the micro SD card in the BBB.
  4. Attach the LAN cable.
  5. Hold the boot button (it's the button near the card) and plug in the BBB. Keep holding the boot button for a few seconds to be sure it boots from the micro SD card. It will remember to boot from the card until the power is cut. Don't worry, there's a way to make it always boot from the SD card, but you don't want to do that until you're sure the OS on the SD card is working. (The procedure is to boot into the built-in drive and rename the MLO file. Thereafter, the firmware will boot from the SD card. I don't know how to get back into the built-in drive, though.)

This is what I got the first time I booted 10.2-STABLE:

FreeBSD/arm (beaglebone) (ttyu0)

login:

The default username and password are root and root.

Networking

You won't be able to do much else if you're not connected to the Internet. The network interface needs to be up and you need to be able to reach remote hosts on the Internet.

DHCP

DHCP is enabled by default (/etc/rc.conf contains ifconfig_DEFAULT="DHCP") so it should just work if you boot while connected (by Ethernet cable) to a DHCP-enabled router.

The boot log of my July attempt to run 10.x showed cpsw0 as the network interface, but there's no sign of it when running ifconfig. I asked about it on the freebsd-arm list. Someone said via email that the BeagleBone's NIC fails at random on startup, for reasons unknown. I set it aside and waited for a new snapshot. After I installed the July 16 snapshot of 11.0, it worked on first boot. It also worked after I installed the September 3 snapshot of 10.2.

/etc/resolv.conf will be automatically rewritten by dhclient as needed, so if you have some preferred nameservers, you need to put that into /etc/dhclient.conf. See [User:Mjb/FreeBSD#Enable a caching DNS server] for details.

Unbound

Unbound is the BIND replacement in FreeBSD 10 and up. It is a caching nameserver that you can enable, but don't do this yet:

  • Add local_unbound_enable="YES" to /etc/rc.conf
  • service local_unbound start

The first time you start local_unbound, it runs resolvconf -u.

Some useful commands:

  • resolvconf -u – regenerate config files in /var/unbound and update /etc/resolv.conf as needed.
  • service local_unbound reload – pick up any changes made to the config files.
  • host freebsd.org – see if freebsd.org resolves
  • host -v freebsd.org – see if freebsd.org resolves (more detailed; shows what IP address was queried)

I'm still trying to figure it out. There are problems that make it impractical to run Unbound at this time:

I saw a note that Unbound must not be started until the system clock is correctly set. This is going to be a problem! As one commenter pointed out, there's a circular dependency: You need DNS to be working in order to set the clock via NTP, but Unbound will ignore info it gets from upstream DNS servers because it thinks those servers are giving it bogus DNSSEC responses from far in the future.

Also, Unbound requires that any upstream resolvers it talks to are DNSSEC-capable. Because of this, I am having trouble my DHCP-supplied resolver, which is an Apple AirPort Time Capsule. It apparently does not support DNSSEC, so I get SERVFAIL responses when using Unbound with the router's IP address as the forwarder(s) in /etc/unbound/forward.conf (as generated by resolvconf).

Initial time set

Login as root (pw: root). The clock will be totally wrong because the BeagleBone Black has no clock battery. So, assuming you have Internet access, you can (on this first boot) run ntpdate to set the clock. Also symlink the appropriate timezone file to /etc/localtime:

  • ntpdate pool.ntp.org
  • ln -s /usr/share/zoneinfo/MST7MDT /etc/localtime

Now check the date and time and make sure it's right:

  • date

FreeBSD's stock ntpd is not set up to run automatically, and I prefer OpenNTPD, so the ports collection has to be installed.

After installing OpenNTPD, it will not be necessary to set the clock unless networking is not available at boot time. I haven't figured out what to do in that situation.

Customize .cshrc & .login

Now is a good time to scp my fancy .cshrc and .login from my other servers.

Don't install pkg

If you try to run pkg, it will install an old version. The better option is to install the ports collection, then install portmaster (see next section). It will install pkg from the ports collection.

Install the ports collection

This will take forever.

  • portsnap fetch extract

Install portmaster

  • cd /usr/ports/ports-mgmt/portmaster
  • make install

At this point it probably tells you to switch to the new pkg format:

  • echo WITH_PKGNG=yes >> /etc/make.conf

make.conf might not exist, so you might have to change the >> to just one >.

This is probably needed if you're using tcsh:

  • rehash

Now set up pkg; it only takes a second since nothing else is installed:

  • pkg2ng

Set build options in /etc/make.conf

Settings in make.conf affect everything built with make, including software in the ports collection. The make.conf(5) manual page explains some of the options available for building kernel and world, but you can also include anything specific to ports, such as to provide default answers to things you would set in the 'make configure' stage. See the ports(7) man page and /usr/ports/Mk/bsd.options.desc.mk for common options (minus the WITH_ or WITHOUT_ prefix, in the latter). Unfortunately, many other options are buried in the individual port Makefiles, not documented anywhere. 

## 'make buildworld' options:

# when building top(1), only allocate enough space it to handle 151 users, rather than 10000
TOP_TABLE_SIZE=151

## ports building options:

# I am using the new package system (required now)
WITH_PKGNG=yes

# my non-Intel CPU (armv6) does not support SSE or MMX
WITHOUT_MMX=yes
WITHOUT_SSE=yes

# support IPv6 and HTTPS
WITH_HTTPS=yes
WITH_IPV6=yes

# don't build or install GUIs, including X11 libraries
WITHOUT_GUI=yes
WITHOUT_X11=yes
OPTIONS_UNSET=X11

# don't waste time on tests when building ImageMagick
WITHOUT_IMAGEMAGICK_TESTS=yes

# when building FreeType, enable subpixel rendering capability (disabled by default due to patent issues)
WITH_LCD_FILTERING=yes

Install nano

I never got the hang of vi. I used pico for years, then nano, which is essentially a pico clone with more features.

  • portmaster editors/nano

Install OpenNTPD

See instructions at User:Mjb/FreeBSD#OpenNTPD.

As mentioned above, what do I do if networking is not available at boot time? And does the clock reset only when power is cut? (in which case not having networking after a soft boot would not be a problem)

Mail

The Sendmail daemon is apparently disabled by default, so immediately some emails from root to root start backing up in the queue. From the messages in /var/log/maillog it looks like the client supports STARTTLS without having to be custom built with SASL2 like in FreeBSD 8.

However, I am going to try OpenSMTPD now.

  • portmaster mail/opensmtpd – also installs various dependencies
  • echo smtpd_enable="YES" >> /etc/rc.conf
  • cp /usr/local/etc/mail/smtpd.conf.sample /usr/local/etc/mail/smtpd.conf

Edit smtpd.conf to your liking, and then:

  • service smtpd start

Starting the service may fail at first: 

Performing sanity check on smtpd configuration:
invalid hostname: getaddrinfo() failed: hostname nor servname provided, or not known
/usr/local/etc/rc.d/smtpd: WARNING: failed precmd routine for smtpd

It's just trying to run smtpd -n at this point. getaddrinfo() is a hostname/IP address lookup function that first tries /etc/hosts and then tries DNS, but it seems like it's not even being called properly. However, it seems to work after you add beaglebone as another 127.0.0.1 and ::1 hostname in /etc/hosts. You should do this anyway because /etc/rc.conf says hostname="beaglebone" and you want this name to resolve.

OpenSSL

When building OpenSSL from the ports collection, I chose these 'make config' options: SHARED, THREADS, SCTP, RC5, DOCS. I disabled SSE2, SSLv2, SSLv3, MD2.

Distributed computing projects

TL;DR: none of the projects supported by BOINC have native support for armv6 processors. This includes my longtime favorite, distributed.net. So it's not an option to run these on the BeagleBone Black right now.

I like to run the distributed.net client on all my machines, but it is not open-source, and there are no builds for ARMv6 on FreeBSD.

Ordinarily you can run it through BOINC with the Moo! Wrapper but this doesn't work either. Here's the general idea with BOINC though:

Install BOINC and start the client:

  • portmaster net/boinc – this will install several dependencies, including Perl. In the 'make config' screens for those, I generally disable docs & examples, X11, NLS (for now), and IPv6 (for now). When installing Perl, I chose to disable 64bit_int because it says "on i386".
  • echo boinc_client_enable="YES" >> /etc/rc.conf
  • service boinc-client start — there's a bug in the port; it writes the wrong pid to the pidfile, so subsequent 'service' commands will fail
  • Create account on the BOINC project page you're interested in
  • Go to your account info on that page and click on Account Keys
  • Create ~boinc/account_whatever.xml as instructed. Put the account key (not weak key) in a file, e.g. ~boinc/whatever.key.
  • boinccmd --project_attach http://moowrap.net/ `cat ~boinc/whatever.key`
  • tail -f ~boinc/stdoutdae.txt — this is the log

Blast! Look what comes up in the log: This project doesn't support computers of type armv6-pc-freebsd

None of the projects I tried (Moo!, SETI@Home, Enigma@Home) are supported. So I went ahead and commented out the boinc_client_enable line in /etc/rc.conf and manually killed the boinc-client process.

I later filed a freebsd-armv6 client port request at distributed.net.

Install MySQL

Ensure the ports collection is up-to-date. There was a fix on 2015-09-15 which affects the ability to build the MySQL ports, among others.

  • portmaster databases/mysql56-server

This will install mysql56-client, cmake, perl, and libedit. cmake has many dependencies, including Python (py-sphinx), curl, expat, jsoncpp, libarchive. Depending on whether you've got Perl and Python already (and up-to-date), this will take roughly 3 to 6 hours.

  • Create /var/db/mysql/my.cnf and put the following in it so that when you start the MySQL server, it's only accessible from localhost:
[mysqld]
bind-address=127.0.0.1

Fetch system source code

Since I installed FreeBSD from a snapshot, it doesn't include /usr/src, the usual home of the base system sources and docs. It's handy to at least have the base system source code, though, because you need it in order to apply security patches and to rebuild components.

Obtaining the code for the first time (probably clobbers any existing /usr/src content):

This URL is for 10-STABLE, of course.

The reason for setting TMPDIR to /var/tmp is because svnlite defaults to using /tmp, which on the snapshots for the BeagleBone is configured (in /etc/fstab) to use a memory file system of only 30 MB, too small to support a checkout of the base system.
