.Dd June 18, 2005 .Dt FWCTL 8 .Os .Sh NAME .Nm fwctl .Nd IEEE1394 control utility .Sh SYNOPSIS .Nm .Op Fl prt .Op Fl b Ar pri_req .Op Fl c Ar node .Op Fl d Ar node .Op Fl g Ar gap_count .Op Fl l Ar file .Op Fl m Ar EUI64 | hostname .Op Fl o Ar node .Op Fl R Ar filename .Op Fl S Ar filename .Op Fl s Ar node .Op Fl u Ar bus_num .Sh DESCRIPTION The .Nm utility is designed to provide a way for users to access and control the .Fx IEEE1394 subsystem. Without options, .Nm will output a list of devices that are/were connected to the bus.
p The following options are available: l -tag -width XmXEUI64XhostnameXX -offset indent t Fl c Ar node Show the configuration ROM on the node. t Fl d Ar node Hex dump of the configuration ROM. t Fl g Ar gap_count Broadcast .Ar gap_count by phy_config packet. t Fl i Ar pri_req Set the .Dv PRIORITY_BUDGET register on all supported nodes. t Fl l Ar file Load hex dump file of the configuration ROM and parse it. t Fl m Ar EUI64 | hostname Set default fwmem target. Hostname will be converted to EUI64. t Fl o Ar node Send a link-on PHY packet to the node. t Fl p Dump PHY registers. t Fl R Ar filename Receive DV stream and dump it to a file. Use Ctrl-C to stop the receiving. Some DV cameras seem not to send the stream if a bus manager exits. If you cannot get the stream, try the following commands: d -literal -offset indent sysctl hw.ieee1394if.try_bmr=0 fwctl -r .Ed
p The resulting file contains raw DV data excluding isochronous header and CIP header. It can be handled by the
a pkgsrc/multimedia/libdv package. t Fl r Initiate bus reset. t Fl S Ar filename Send a DV file as isochronous stream. t Fl s Ar node Write to the .Dv RESET_START register on the node. t Fl t Show the topology map. t Fl u Ar bus_num Specify the IEEE1394 bus number to be operated on. .El .Sh FILES l -tag t Pa /dev/fw0.0 .El .Sh EXAMPLES Each DV frame has a fixed size and it is easy to edit the frame order.
p .Dl "fwctl -R original.dv"
p Receive stream.
p .Dl "dd if=original.dv of=first.dv bs=120000 count=30"
p Get first 30 frames (NTSC).
p .Dl "dd if=original.dv of=second.dv bs=120000 skip=30 count=30"
p Get second 30 frames (NTSC).
p .Dl "cat second.dv first.dv | fwctl -S /dev/stdin"
p Swap first and second 30 frames and send them to DV recorder.
p For PAL, replace .Dq Li bs=120000 with .Dq Li bs=144000 . .Sh SEE ALSO .Xr fwip 4 , .Xr fwohci 4 , .Xr ieee1394if 4 , .Xr sbp 4 .Sh HISTORY The .Nm command first appeared in .Fx 5.0 , as c fwcontrol . It was added to .Nx 4.0 under its present name. .Sh AUTHORS .An Hidetoshi Shimokawa Aq simokawa@FreeBSD.org .An KIYOHARA Takashi Aq kiyohara@NetBSD.org .Sh BUGS This utility is still under development and provided for debugging purposes.
