remote update issue

Thanks a lot!

But i still have some questions as follows:

1.If using the ALT_ASMI core to control the EPCS device(like EPCS4), so ,the factory image how to communicate with the ALT_ASMI core ?

2.What is the relationship between the factory image and the application image?

3.For the factory image, how to command the ALT_ASMI core to download the application image?

PS:In my design,i use the user logic to control the whole procedure. But i don't know clear about the relationship between the remote update core and the factory image,application image.
