Is factory image still runing in RSU?

Hi, everyone

I'm using remote update controller core in Cyclone III board.

Firstly, I want to test if the ruc core can work functionally or not. So I stored factory image(hw0+sw0) at 0x0 and application image(hw1+sw1) at 0x00100000 in EPCS16 device.

Software sw0 of factory image includes a reconfiguration after 5 seconds. I can see that the factory image is running correctly through one led in first 5 seconds.

Then the factory image execute the reconfiguration. I can also see that the application image is loaded correctly. The software sw1 of application image doesn't run. After reading some other threads I know this is the result of wrong bootloader code.

But after the reconfiguration, I found that the factory image didn't run any more.

My questions are:

(1) Is factory image still running when factory image has reconfigured to application image?

(2) If it doesn't run any more, who will communicate with the remote host and receive the updating data?

Thank you for help!
