Yes @nikfreak, my fault, now everything is working fine. I successfully can shoot now at 1376 x 688 more than 20 secs...
But there is a little problem with the quality of the image. Small green/blue dots appear on some areas. I'm not sure is that the same problem like I already read in EOS M forum.
You can take a look here, over the front light and car fender, tire:

It's 100% crop
