Problems with EPCS1 with Cyclone II

[Altera_Forum]

I've made a project using FPGA Cyclone II (only one FPGA) EP2Q5208C8 and EPCS1 (file.pof generated with compressed bit streams) to configure in JTAG and program in AS mode. Everything seems right, but in AS mode the programming it's not succeeded. I am using Quartus II 9.1 with 2 service pack installed. In mode JTAG (file.sof) works well. 

  I received the message "Can't not recognize the silicon ID for device 1".    I am using combining JTAG and Active Serial Configurations schemes. I have added 120 Ohms resistor between lines DATA, DCLK, nCS, ASDI of flash memory and FPGA like starter kit Altera cyclone II.  Please, could you help me? Thanks a lot.  plbenko

The "Can't not recognize the silicon ID" error is unspecific, it simply tells that the programmer can't connect to the serial flash. Without seeing the complete schematic related to AS configuration, I won't guess about possible reasons.   Besides programming the serial flash through the dedicated AS interface, you can also use indirect JTAG programming. It requires conversion of the configuration to a *.jic file.

Thanks for your answer. The scheme it's from Cyclone II device handbook pg 13-63, vol 1. figure 13-25. I left both MSEL0 and MSEL1 to GND ( to select low frequency), and added 120 Ohms resistors between FPGA lines and flash prom EPCS01 like I saw inside schematic starter kit cyclone II Altera. How can I make the conversion to *.jic file to use indirect JTAG programming?

I think you'd better upload your schematic to the thread and we can give you some advice based on it..
