Hi, 

I have two cyclone I devices on my board I have kept a provision to configure them in active serial mode. 

 

I am using one epcs4 configuration device for each fpga. 

 

right now i am using separate jtag connectors for both the fpgas, Is there any way in which i can configure both the fpgas using the same jtag connection? 

 

thanks in advance

Yes, put them in a JTAG chain (connect TCK and TMS in parallel, chain TDO to TDI)
