The problem of boot has resolved, here is my resolution:

1. Download the corresponding factory image of My pixel from google office website(https://developers.google.com/android/images);
2. Flash that image into my Pixel under instructions described in the office website;
3. After flash office factory images successfully, flash the images built from this project in to pixel;
4. Done.
