FreeBSD developer's notebook All Things FreeBSD

FreeBSD/Pi setup HowTo

Took some time but it seems we're there too :)

Alexander Rybalko, who works on USB drivers for the platform got remote telnet shell to the device: http://pastebin.com/6NqQLWD2

Having fixed serial console for userland applications (two lines change) and after some tweaking of SDHCI driver I got access to multiuser shell too: multiuser.txt
Still not usable for putting together distros but stable enough for those who are willing to get their hands dirty with kernel side.

Here is short how to on getting FreeBSD boot on Raspberry Pi:

Get sources:

git clone git://github.com/gonzoua/freebsd-pi.git
cd freebsd-pi
git checkout rpi

Fetch u-boot files from here: freebsd-pi-uboot-20120806-sd.tar.gz.

Build sources and create SD card image with script like this:
#!/bin/sh
set -e

export TARGET_ARCH=arm
export SRCROOT=/usr/home/gonzo/Sources/freebsd-pi
export MAKEOBJDIRPREFIX=/usr/home/gonzo/Sources/obj
export KERNCONF=RPI-B
KERNEL_BIN=`realpath $MAKEOBJDIRPREFIX`/arm.arm/`realpath $SRCROOT`/sys/$KERNCONF/kernel.bin

make -C $SRCROOT kernel-toolchain
make -C $SRCROOT KERNCONF=$KERNCONF WITH_FDT=yes buildkernel
make -C $SRCROOT TARGET_CPUTYPE=armv6 MALLOC_PRODUCTION=yes buildworld

IMG=bsd-pi.img
rm -f $IMG
dd if=/dev/zero of=$IMG bs=128M count=8
MDFILE=`mdconfig -a -f bsd-pi.img`
gpart create -s MBR ${MDFILE}
gpart add -s 32m -t '!12' ${MDFILE}
gpart add -s 896m -t '!12' ${MDFILE}
gpart set -a active -i 1 ${MDFILE}
newfs_msdos -L boot -F 16 /dev/${MDFILE}s1
newfs /dev/${MDFILE}s2
mount_msdosfs /dev/${MDFILE}s1 /mnt
tar -x -v -z -C /mnt -f freebsd-uboot-sd.tar.gz
cp $KERNEL_BIN /mnt
umount /mnt
mount /dev/${MDFILE}s2 /mnt
make -C $SRCROOT DESTDIR=/mnt installworld
make -C $SRCROOT DESTDIR=/mnt distribution

# Minimal config
echo 'hostname="freebsd-pi"' > /mnt/etc/rc.conf
echo '/dev/mmcsd0s2 / ufs rw 1 1' > /mnt/etc/fstab

umount /mnt
mdconfig -d -u $MDFILE

dd image to SD card, insert it to Raspberry Pi and check serial port for some output

There is also U-Boot configuration that uses dhcp/tftp method by default freebsd-pi-uboot-20120806-netboot.tar.gz. It's more suitable for kernel hacking but requires environment setup.

    Hello There!!

    Thans a lot for the imformation!!

    Thank you for great information.

    Now I’m creating image file and I will test this image tomorrow with my r-pi.

    By the way, I have below error in script.

    x boot.scr: Can’t set user=1001/group=0 for boot.scr
    x bootcode.bin: Can’t set user=1001/group=0 for bootcode.bin
    x cmdline.txt: Can’t set user=1001/group=0 for cmdline.txt
    x config.txt: Can’t set user=1001/group=0 for config.txt
    x loader.bin: Can’t set user=1001/group=0 for loader.bin
    x start.elf: Can’t set user=1001/group=0 for start.elf
    x u-boot.bin: Can’t set user=1001/group=0 for u-boot.bin
    x uEnv.txt: Can’t set user=1001/group=0 for uEnv.txt
    tar: Error exit delayed from previous errors.

    So, I change tar line as below(added –uname root)
    [NEW]
    tar -x -v -z –uname root -C /mnt -f freebsd-uboot-sd.tar.gz

    Just wanted to feed back, major thanks for your work.

    I can report that following the above instructions I have a RPi booted with 10-Current. Had a bit of an issue building on 9.0-Release due to tar not supporting –uname out of the box, but solved that just by extracting, reowning and recompressing the file to work with the script.

    One comment though is that the serial interface in uboot is set to 115200, but the first tty is set to 9600… Adjusting the tty to 115200 was easy enough and let me get onto the device!

    Thanks again! Looking forward to some usb-age and network-age.

      I don’t know the state of affairs in OpenBSD but if they have support for armv6 (which seems to be the case) – I see no major road blocks for making a port.

    Hi, great job,
    are there any possibility to merge port files and FTD with 9-RELEASE?
    I was trying to do this using files from your git-src but I think there is to much changes made.

      Yes. It’s known issue with later version of FreeBSD, both CURRENT and 9.1. I started merging bits back to subversion, so you can try building latest HEAD from svn with this patch: http://people.freebsd.org/~gonzo/arm/rpi/rpi-head-20120825.diff

    Btw is there any timeline for FreeBSD Raspberry Pi development? Are you planning to release the .img here? since no one doing so for FreeBSD arm ports

    Very cool. I have no u-boot experience and I am just beginning to explore it. I would like to dhcp/tftp boot the rpi, with a linux kernel though. I was wondering, if you know, would booting a linux kernel be as simple as substituting the linux kernel for a bsd kernel you are using in this example. Thanks, I’m looking at as many u-boot resources as I can find but I’m still a little lost.

      Just replace

      with
      make -C $SRCROOT MALLOC_PRODUCTION=yes TARGET_CPUTYPE=armv6 buildworld
      and it should work.

      Also make sure you did git checkout rpi after git clone.
      No need to apply any patches for this tree

        Sorry for the iterations we are going through but it still fails.

        Here is what I have:

        1) this is my kernel:
        $ uname -a
        FreeBSD xxxxx 10.0-CURRENT FreeBSD 10.0-CURRENT #3 r239996M: Sun Sep 2 01:45:39 PDT 2012 root@xxxxx:/usr/obj/usr/src/head/sys/GENERIC amd64

        2) I checked out the git tree:
        git clone git://github.com/gonzoua/freebsd-pi.git
        cd freebsd-pi
        git checkout rpi

        3) here is the buildscript:

        #!/bin/sh
        set -e

        export TARGET=arm
        export TARGET_ARCH=arm
        export SRCROOT=/home/hari/git_stuff/freebsd-pi

          I keep forgetting about this issue. Sources grew incompatible with -CURRENT. Try building svn. Checkout latest head from http://svn.freebsd.org/base/head
          Then apply this patch: http://people.freebsd.org/~gonzo/arm/rpi/rpi-head-20120902.diff

          Use the same script but TARGET_ARCH should be armv6 and remove TARGET_CPUTYPE=armv6 from buildworld line
          The rest is just the same.
          Sorry about this breakage. I totally forgot about it :(

            I’ve had no luck with this (will post my build script below) – I should point out I don’t have serial hardware yet, so I can’t see what’s going on, but I’ve uncommented the 4 lines (sc kbdmux etc) in RPI-B for the frame buffer so I should expect to see kernel boot messages on screen (right?) – I just get the rainbow coloured screen and no activity light thereafter. (I wrote an /etc/rc.local script to mount the boot partition and write dmesg etc to it so at least I could see if it made it that far, but that doesn’t seem to be happening)

            Do I absolutely have to have serial hardware connected to make it boot?

            I’m building on FreeBSD 9.1 RC1 if that makes a difference, the patch you supply above seems to apply correctly with no issues and the boot partition contains my kernel.bin:

            -rwxrwxrwx 1 matthewf staff 2823544 7 Sep 14:36 KERNEL.BIN

            I will have another go after posting this, including a complete rebuild of everything (the kernel.bin looks sane and is ARM

            /usr/obj/arm.armv6/usr/src/sys/RPI-B]# file kernel kernel.bin
            kernel: ELF 32-bit LSB executable, ARM, version 1 (FreeBSD), dynamically linked (uses shared libs), not stripped
            kernel.bin: data)

            I couldn’t figure out if USB/Ethernet support was in HEAD, but I see Alex Rybalko’s paste bin seems to indicate he has it working?

              My latest conclusion is that u-Boot isn’t working (or I need serial hardware connected [ordered]) I’ve even tried the net boot tar.gz version – which you’d expect to DHCP and try to grab a kernel – but nothing happens.

              [I've now updated HEAD and got the DWC OTG bits too].

              Wish I could figure out what was wrong – is it possible to build a FreeBSD kernel that boots in the “normal” way without u-Boot?
