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

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.

Initial time set

Login as root (pw: root). The clock will be totally wrong because it has no 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

If you are using FreeBSD-CURRENT, several lock order reversal messages with stack traces come up. These are normal and are for debugging FreeBSD-CURRENT. See https://www.freebsd.org/doc/faq/troubleshoot.html#idp59162064

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

Install nano

  • 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.
