ASMI IP to update the FPGA problem

Hello everyone,
I recently want to use ASMI's IP to update the content of FPGA,
And my architecture is shown in Figure 1

My question is,
After I deleted all the unused FF data after the .rpd file and wrote the EPCQ through ASMI, I could not successfully configure the FPGA after powering on again.
I have compared the data before and after writing, and they are no different.

Are there any suggestions for my approach?

Thanks for your answers.
