Booted it and managed to run it for a short while before it went into panic, and after that it panics quite frequently. I'll get a screen shot next time. Not very stable currently. Is there any chance to get the 10-STABLE running on the Raspberry Pi 2?

Bex: I get a panic after writing something bigger than a few bytes to the SD card. Do you get this panic as well?

This is on FreeBSD 11.0-CURRENT r282767.

The same SD card works fine under Linux. So I don't think that the card is faulty.
I wonder if putting the root file system on a USB stick for now will be more stable.

Today I installed v11.0 for raspberry Pi 2 and it works brilliantly: ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/arm/armv6/ISO-IMAGES/11.0

No errors, kernel panic or anything. It has so far an uptime of 7 hours, and no issues at all.

Wifi dongle (Vilros) was detected, however I had to cp /boot/loader.rc.sample /boot/loader.rc as well as tweak the /boot/loader.conf for the wifi dongle, mine was just:

Code:
legal.realtek.license_ack=1
if_urtwn_load="YES"
and a reboot aftewards.

So far, wireless works (standard ifconfig and wpa_supplicant setup). SSH works. 2-factor Google authenticator works.

If you have any questions, please let me know.

Cheers from London
Rami

Are you able by any chance to test the sd card in another rpi2? Just to discard any hardware/power supply issue?

(might be that you are already using that rpi2 for other images, so it might not be useful my reply!)


I tested this image: http://ftp.freebsd.org/pub/FreeBSD/snapshots/arm/armv6/ISO-IMAGES/11.0/FreeBSD-11.0-CURRENT-arm-armv6-RPI2-20150509-r282694.img.xz

However, it goes into boot loop for me. Here is the log:

Not sure it's the right place to ask but I'm a recent FreeBSD convert with a few days experience on other hardware and never really had any issues. Been trying to get the Pi 2 version up to just having a desktop and browser, but failing at the first hurdle because 11.0 is telling me that xorg-minimal doesn't exist for it. Any clues..?

Hi,
FreeBSD 11.0-CURRENT for RaspberryPi 2 is still experimental and therefore it does not guarantees 100% functionality.

About x11/xorg-minimal, if you are trying to install it with pkg, it is possible that it is not available from packages, maybe you should try compiling from ports, although it would take some time, given that the CPU is not powerful enough.

If you want to use your RPi2 to browse the internet (or just to have a GUI...), my guess is that Linux is ideal for you (Raspbian, etc.).

Totally aware of how experimental it is, and I just happen to prefer FreeBSD where possible and find it an interesting alternative in general. I know it exists for 10.1 on the older Pi so assumed I was likely doing something wrong here. Guess I can dig out my model B 512mb revision and play around with that in the meantime. Perhaps I will have a shot at compiling it. I have four devices at this point running FreeBSD and am very keen on getting it going on the Pi 2 as I enjoy figuring out alt-OS's. There's just a lot of things about FreeBSD that appeal to me, and I think it will make a great companion to the Pi 2 some day. Everyone working on it? Keep at it!

I tried running FreeBSD 11-Current on my Raspberry Pi 2 today. The first time I started it up, the Pi was headless. Networking and OpenSSH were running and I could connect to the Pi over the network. I couldn't get logged in though. Tried a bunch of different passwords, including an empty password (just pressed Enter), but could not get logged in remotely.

Later I hooked the Pi up to a monitor and tried booting FreeBSD 11. The Pi shut itself off after about 20 seconds. I tried half a dozen times to boot the Pi with and without any devices attached. It always shut off within 20 seconds and provided no video output.

What I found weird was the first time the Pi obviously booted okay since it was accepting remote login attempts. But all future boot ups crashed in seconds, resulting in the Pi shutting off.

Does FreeBSD's ARM port do anything to change its files or disk layout? Trying to figure out why the OS would only boot once and then crash on each subsequent boot.

Also, am I correct that the password is blank and that it is not possible to login remotely with the default image?

Thanks, that solved the problem! Motherboard USB power is enough for RPI1, but not for RPI2!

So it is working splendidly now, thanks to everyone for your hard work! It is very much appreciated.

The same thing often happens with the Pi 1 images as well. It is not so reliable just yet, give it time.

I recopied my FreeBSD 11-Current image to the microSD card and gave it another try. This time it worked. I realized what probably happened before was FreeBSD turns off the Pi's external light while Raspbian leaves the light on, so it looks like the Pi is powering off. It takes a while for my montor to detect a signal from the Pi when its running FreeBSD too, so the combination of a blank monitor and no light make it seems like the Pi wasn't on-line. So the first time around I probably interrupted the Pi's power while the file system resize was in progress.

Anyway, I got the Pi running, set up an account I can ssh into and things seem to be running smoothly.

At this point the one thing I feel I am missing is ZFS. When the Pi is running Raspbian, I can access my ZFS-managed devices. It seems the FreeBSD 11 image doesn't include a ZFS module or the kernel source code.

Does anyone here know if the FreeBSD ZFS module will build on the Pi? Or if there is a repository where I can download a pre-built ZFS arm module? I'd rather not have to rebuild the kernel from scratch on the Pi.

I'd like to head off any comments about ZFS not working well with the Pi's limited hardware. I've been managing 2TB of data on my Pi using Raspbian and ZFS for a month now without any problems.

Update: I was able to install the zfs module by downloading the FreeBSD source code and compiling the following modules in the sys/modules direcotry: opensolaris, zlib and zfs. Copying the resulting .k* files to the /boot/kernel directory allowed me to load the ZFS module and access my external hard drive that is managed by ZFS.

Further, I have discovered that while I can access this external drive, some copy operations cause my Pi to completely hard crash. For example, I can copy any one file I like, but copying a whole directory (ie cp * /to/destination/) brings down the operating system.

I'm also noticing sometimes files I create on the root partition (formatted with UFS) do not always survive the crash. Perhaps UFS isn't syncing in time to save its data before the crash happens. Still working on this.

Memory consumptionis fairly low, the whole Os, ZFS included, is using around 200MB of RAM.

Second update: I have found I am able to create/move/delete many files at once on either my ZFS volume OR the UFS partition. The crash only happens, it seems, when I try to bulk copy files from one file system to the other, in either direction. I can, for example, unpack the ports tree or copy the kernel source code around to various locations, so long as I stay within the boundaries of the respective file systems.

Thanks for your reports, NewGuy! It is good to know that ZFS can be installed, but is unstable for some reason. I hope the crash did not harm your ZFS pool!

I will share some of my observations having run the Pi 2 for an evening... Surprisingly, I found the network I/O performance was actually worse than the Pi 1 unless the device is running in turbo mode, and then it was almost the same (but still a little bit worse).

Unfortunately the performance is much worse than I'd hope, maxing out at less than 10 megabits/s (about 10% of the theoretical maximum of the 10/100 adapter). While trying to figure out the cause I discovered it is probably because unlike Linux, FreeBSD is using PIO mode instead of DMA mode for USB transfers. See the links below for some more info. Since this is not a CPU limitation, the beefier Pi 2 does not improve the situation.

So I was not so impressed with Pi 2 on FreeBSD at this point. Oh well, maybe one day.

The crashes do not appear to have harmed my ZFS zpool, thanks for the concern. The pool passed its scrub test.

I found some further interesting quirks with running FreeBSD+Pi+ZFS. Since there aren't any official packages for the ARM architecture, I decided to download the ports tree and install software from there. I ran into these interesting issues:

1. portsnap fetch does not work, portsnap(8) reports the server's meta-data is wrong and refuses to download the ports tree. I checked my portsnap configuration file and it is the same as my portsnap config file on other FreeBSD servers where portsnap works.

2. I downloaded and unpacked a tarball of the ports collection. This tarball unpacked fine on the ZFS volume. I could then go into the ports tree, open Makefiles, cat patches and confirm everything is there. However...

3. When I try to run make in any of the port directories, make reports no target was found. If I then try to open the Makefile, it is empty. ls -l shows the file is still the same size, but vi and cat show an empty file.

4. I was curious to see if this meant ZFS was not writing data properly or not reading data properly where the Makefiles were concerned. I exported my ZFS pool and imported it on another operating system (also running on the Pi). The data is definitely there and readable from Raspbian on the same ZFS volume. so the files which appeared empty in FreeBSD are there and whole and readable in Raspbian.

I'm not quite sure what to make of this. It seems I can create files, many files, and read them on the ZFS volume from FreeBSD. I can read them, I can export/import the pool and read the data from another OS. However, running make on three different ports all resulted in errors of "no target found" and I was unable to read the Makefile from within FreeBSD again. I can read the files fine in Raspbian though.

A zpool scrub shows the pool is fine. I haven't seen anything quite like this before. It seems FreeBSD+ZFS+RPi works about 95%, but data is sometimes corrupted while being read/accessed. Long story short: FreeBSD+ZFS appears to work on the Pi, but I wouldn't trust it.

Update: Wondering if this might be an allocation/versioning issue. Raspbian is probably using an older version of ZFS and it used 512 byte allocations. FreeBSD reports it wants 4096 byte allocations and runs a newer version. Planning to test this idea with another (spare) drive to see if I can duplicate the problem and/or find a solution.

Another update: I decided to experiment to see if the system crashes I was experiencing on FreeBSD 11-Current (arm) were due to incompatibilties between the Raspbian ZFS file system and the FreeBSD implmentation.

I grabbed a spare hard drive and plugged it into my Raspberry Pi 2 running Raspbian. I formatted the disk with ZFS and copied a directory tree onto the new ZFS volume. This worked fine and I could access my files, copy them back, etc.

Then I swapped out my Raspbian SD card for my FreeBSD card and booted the same Pi. I imported the new ZFS volume and found I could browse the file system, but copying more than one file at a time to or from the ZFS volume would cause the operating system to immediately crash. In other words, I've reproduced the copying crash using multiple external drives at this point.

My next step was to destroy the Raspbian-created ZFS file system and create a new file system on the same external drive using FreeBSD's implementation of ZFS. The file system was created. Here is where it gets interesting.

With the FreeBSD-created ZFS volume I was able to copy large trees of files to the ZFS volume from my UFS partition. However, when I tried to copy files back _from_ the ZFS volume to my UFS partition, the operating system immediately crashed.

I booted into FreeBSD again and performed another experiment, and this is where it goes from interesting to just plain weird. I copied kernel soruce code onto the ZFS volume. If I go into any directory and run "cat Makefile" I can see the contents of the Makefile. However, if I run "make" then it spits out an error saying there is no target. If I run "cat Makefile" again, there is no data in the Makefile. The command "ls -l" shows the file is still its full, normal size, but I cannot read any data in the file, it appears to contain zero bytes. I thought the file might be truncated, but it's not. If I use
Code:
zfs umount MyData
zfs mount MyData
and go back into the same source code directory, the Makefile is there and I can read it and edit it. But if I run "make" again the contents of the Makefile disappear until I umount/mount the ZFS pool again.


To sum up, there are three problems here:
1. FreeBSD and Raspbian have slightly incompatible ZFS implementations.
2. Running "make" on source in a ZFS pool temporarily wipes the Makefile. This makes it impossible to build ports or kernel modules or other items from source code in ZFS. Building source using "make" on UFS does work.
3. Copying _to_ a ZFS volume works, but copying from ZFS to UFS causes an immediate and total system failure.

Question 1: Can anyone else reproduce these problems?

Question 2: Which mailing list or component team should I bring this up to? I'm not sure if these issues qualify as Make bugs, ZFS bugs or ARM bugs.

Also, am I correct that the password is blank and that it is not possible to login remotely with the default image?
Hi Newguy, I'm trying to run freebsdFreeBSD on my Raspberry Pi 2. I wrote the image FreeBSD-11.0-CURRENT-arm-armv6-RPI2-20150601-r283896.img to my microsd card, it booted and SSH responded, but I wonder what's the default user name and password?

The username is root and the default password is blank. However, root logins are blocked through OpenSSH by default. You need to boot up the Pi with a keyboard and monitor attached and create a new user account before you can login remotely.

Thanks, now I can login through SSH with an ordinary username.

I've gone ahead and put both FreeBSD-11.0-CURRENT-arm-armv6-RPI2-20150601-r283896.img and FreeBSD-11.0-CURRENT-arm-armv6-RPI2-20150618-r284544.img on microSD cards, installed them in my RPi 2, and booted with a monitor and keyboard plugged in. However, both are requiring passwords -- leaving it blank for the root password isn't working, even from console. Is there some other trick or hoop I may be missing?

According to arm_create_user() in src/release/tools/arm.subr the logins are:
Code:
login: root
password: root

login: freebsd
password: freebsd
The 2nd should work over ssh.

It's got to be simple.
Headless Pi2.
Burnt the image.
Booted up and ssh'd to box with user/password of "freebsd"/"freebsd".
su -

Won't accept root password of root as above message says.

What am I missing?

The RPi wiki page states as follows:
2015-06-26: The default passwords for the images are freebsd/freebsd and root/root
I'm not sure if the passwords has been changed since then, but in case of doubt, you can ask in the freebsd-arm mailing list.
