Hi,
I am trying to run a Kodak camera from the firewire with the attached program.
(I am currently debugging the packet sending using an Oxford disk).
The attached progam is attempting to send a command orb inquiry to the
device.
da4 at sbp0 bus 0 target 0 lun 0
da4: <Oxford S (null) 0000> Fixed Simplified Direct Access SCSI-4 device
sbp0:0:0 XPT_GET_TRAN_SETTINGS:.
sbp0:0:0 XPT_PATH_INQ:.
da4: 50.000MB/s transfers
da4: 28615MB (58605120 512 byte sectors: 255H 63S/T 3648C)
After the login, running the program, the response I get is:
fw_rcv: unknown response tcode=2 src=0xffc1 tl=20 rt=1 data=0x84516ce3
try ad-hoc work around!!
no use...
Apparently, the response destination does not agree with the original source.
Questions.
What to use for ---.mode.wreqb.src ?
What about dest_lo ?
Is wreqb the correct mode ?
Where does the response go ?
Thanx,
