FreeBSD/arm for Marvell Orion, Kirkwood and Discovery systems-on-chip
![/!\](/moin_static1911/modern/img/alert.png "/!\"){kind=small}
There is no support available anymore for these systems. FreeBSD 8.2 was the last version that was really stable.
This is a short introduction into running FreeBSD 8.x and 9-CURRENT on the family of Marvell integrated systems-on-chip, including
- 88F5181, 88F5182, 88F5281
- 88F6281
- MV78100
The chips have programmable endian order, but only Little Endian mode was tested so far and all below examples assume this. In particular, the [lack of] arguments for build targets cause the created binaries to be LE.
Build world
$ cd ${SRC}
$ make -j 8 buildworld TARGET_ARCH=arm
Install world into the NFS-exported location
$ su # setenv DESTDIR /nfsroot/arm-8-le # mkdir -p $DESTDIR # make installworld TARGET_ARCH=arm # make distrib-dirs TARGET_ARCH=arm # make distribution TARGET_ARCH=arm
Adjust configuration for diskless use
# echo 'sshd_enable="YES"' > $DESTDIR/etc/rc.conf # echo 'rpcbind_enable="YES"' >> $DESTDIR/etc/rc.conf # echo 'nfs_client_enable="YES"' >> $DESTDIR/etc/rc.conf # echo 'rpc_lockd_enable="YES"' >> $DESTDIR/etc/rc.conf # echo 'rpc_statd_enable="YES"' >> $DESTDIR/etc/rc.conf
Most likely the $DESTDIR/etc/fstab should be updated according to the local configuration. Consult diskless(8) for additional info.
Build kernel
There are dedicated kernel config files for different Marvell development systems per each family, use one of the following:
$ make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F5XXX $ make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F6XXX $ make buildkernel TARGET_ARCH=arm KERNCONF=DB-MV78XXX $ make buildkernel TARGET_ARCH=arm KERNCONF=SHEEVAPLUG $ make buildkernel TARGET_ARCH=arm KERNCONF=DREAMPLUG-1001 ### Note for Nor based flash DreamPlugs you need a special configuration and ### you will need to change the kernel DREAMPLUG configuration to NFS booting unless the ### default DREAMPLUG loads from the SD card.
Move kernel to TFTP area
In the simplest scenario a pure binary version of the kernel (kernel.bin file) will be directly run from U-Boot. In this approach the kernel.bin needs to be placed manually in the TFTP-exported directory, which is accessible from the target.
$ cp ${OBJDIR}/sys/DB-885XXX/kernel.bin /tftpboot/mv5281/
Setup TFTP server
In /etc/inetd.conf, uncomment the following two lines:
tftp dgram udp wait root /usr/libexec/tftpd tftpd -l -s /tftpboot tftp dgram udp6 wait root /usr/libexec/tftpd tftpd -l -s /tftpboot
Make sure the inetd(8) server is enabled in /etc/rc.conf:
inetd_enable="YES"
Setup NFS server
Add the following to the /etc/rc.conf on the host:
nfs_server_enable="YES" mountd_enable="YES" rpcbind_enable="YES" rpc_statd_enable="YES" rpc_lockd_enable="YES"
Add a line to /etc/exports, like this:
/nfsroot/arm-8-le -maproot=0 -network 10.4.50/24
Setup DHCP server
Install the server from net/isc-dhcp42-server. Add a section to /usr/local/etc/dhcpd.conf like this:
subnet 10.0.0.0 netmask 255.255.0.0 {
range 10.0.0.1 10.0.0.255;
option domain-name "internal.example.org";
option broadcast-address 10.0.255.255;
default-lease-time 600;
max-lease-time 7200;
filename "mv5281/kernel.bin";
option root-path "10.0.0.201:/nfsroot/arm-8-le";
}
Boot the kernel from U-Boot

openrd-client specific notes
To access the console, you have to use the MicroUSB connector labeled "SYSTEM". It's not possible to use the usual RS-232 serial port instead. After connecting to FreeBSD host, two USB devices show up:
uftdi0: <OpenRD JTAGKey FT2232D B> on usbus0 uftdi1: <OpenRD JTAGKey FT2232D B> on usbus0
Console is on the second one (/dev/cuaU1). The default speed is 115200, 8N1.
