Hi,
I am going to try this one again. This time it really is a Kodak camera,
not an Oxford disk. (The result fails the same way.) The Kodak is not
a SCSI device. The Kodak camera is logged in and attached by SBP-II as
follows:
firewire0: node_id = 0x8800ffc0, non CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 0 (me)
fw_set_bus_manager: 63->0 (loop=0)

I now would like to run a program which accesses the camera directly through
firewire.c by way of iotcl. (This is what fw_tap.c does to run the ethernet
code.) After opening "/dev/fw1" and allocating asyreq, I have the following:
asyreq->req.type = FWASREQEUI;
asyreq->req.sped = FWSPD_S400;
asyreq->req.len = 120;
asyreq->req.dst.eui.hi = DEVICE_EUI_HI;
asyreq->req.dst.eui.lo = DEVICE_EUI_LO;
asyreq->pkt.mode.common.tcode = FWTCODE_WREQB;
asyreq->pkt.mode.wreqb.len = htons(24);
asyreq->pkt.mode.wreqb.src = 0; /* ??? */
asyreq->pkt.mode.wreqb.dest_lo = htonl((int)resp); /* ??? */
asyreq->pkt.mode.wreqb.payload[0] = htonl(1 << 31);
asyreq->pkt.mode.wreqb.payload[3] = 0; /* ??? */
asyreq->pkt.mode.wreqb.payload[4] = htonl(0x8a900000);
asyreq->pkt.mode.wreqb.payload[5] = htonl(0x12000000);
asyreq->pkt.mode.wreqb.payload[6] = htonl(0x24000000);
ioctl(fd, FW_ASYREQ, asyreq);
Note that the inquiry command (the first byte of the command data block,
i.e., the 0x12 in payload[5]) is the same as already sent by SBP-II.
See the above XPT_SCSI_IO. This results in:
fw_rcv: unknown response tcode=2 src=0xffc1 tl=34 rt=0 data=0x84511a82
try ad-hoc work around!!
no use...
The command orb has been sent, but the response fails. A look at the
code for firewire.c shows that this message is generated because a call
to fw_tl2xfer indicates that the response destination does not agree
with the original source. How can I get the response back to my program ?
Thanx,
