Hello,

little bit late answer, but better late than never :-)

There is definitely no image (or not the whole image) read in.
Perhaps extending the first sleep a bit (0.04 is less)?
Can You send me the whole output in /var/log/messages.

Sorry, no further idea at the moment :-(

Dear MStein,

I did the following debugging process,

[root@203 itifg-7.2.1]# /sbin/rmmod itifg

[root@203 itifg-7.2.1]# /sbin/insmod ./itifg_g.o

then i ran my code for the shutter,

while(input(-1)==""){
image_par(1,"send","0x82 0x88"); # setting CCD to external trigger mode
image_par(0,"run");
p "test";
image_par(1,"send","0x82 0x89"); # sending trigger signal using serial port

#image_par(0,"run");
sleep(0.04);
p "test1";
image_get(0,image);
sleep(1);
}

This is the output at terminal

1320.FOURC> qdo test1.mac

this is in itifgIoctl.c

this is in itifgMain.c. I think line 1003 is a hot canidate.

Yes, this is what I ask You before. If You remove the normal driver
with 'rmmod itifg' and insert the debugging one with 'insmod ./itifg_g.o'
You can see more debugging output in /var/log/messages.

The comment above line 1003 says, that the last operation hasn't finished
yet, perhaps You (or the shutter) are to fast/slow/unsynchronized?

I think this don't fix the error, it makes it only more difficult to
find.

See above and let us again try to load the debugging module!

I'm back at Monday, we have a spare day here.
