Cyclone V remote update

Hi,

When I implemented remote updates using Cyclone V, I need to update bitstream file in EPCS using SPI communication interface. The official website has no routine，in which I only find the routine that factory and application image switch over remote.

Altera ALTASMI IP can only carry out information interaction between FPGA and the general purposememory portion of the EPCS devices. I really want to know if there is a IP can simulation AS mode download process, which can implement bitstream file transport.

thanks and regards
