Hi, Everybody , i am freshman of Altera FPGA, 

 I have some problem for remote Upgrades,   I have been see how to do remote Upgrades by Uart(RS-232 or 422 or 485),   and this web position is : www . grigaitis.eu/?p=514   but I don't understand how to implement remote Upgrades.   Have any easy about remote upgrades Example(SOPC and FW and SW) give me reference ?   if i will do remote upgrades,whether is send .ttf file or not ?

I don't understand your question... Your link already gives all the details, and provide example hardware and software designs. What do you need more?

sorry, 

 about web "www . grigaitis.eu/?p=514", that is use on the EP3C25.   because of the EP3C16 internal memory less then EP3C25, so i need to modify memory setting, but i don't understand how to modify.   so have any document give me reference.   and have any docutment or Explame or source code(use on EP3C16 + EPCS + AS mode + UART) give me reference.   thanks

Decrease the on-chip RAM size, from 40k to something like 32k or 28k. The other components can stay the same.

I have written state machines for factory and application images -cyclone3-AS mode-EPCS16. 

Do I need ALTASMI mega function to connect serial device(I2C)? I read that there is no need of ALTASMI.But,how the data transfer takes place between I2C and EPCS?  How do I build SOPC?Greatly appreciate if anyone can guide me!
