Only produce one image on IMX219

[jasonchenPJ]

Hi, @6by9
I want to produce multiple RAW images with this projcet.
Now, I only get one RAW image after enter the following command:
$ raspiraw -y 0 -t 3000 -f 2 -hd -o out.%04d.raw

According to my understanding, 6 RAW images should be produced.

That's my setting:

Do you have any suggestions for me? thanks
