Hello tns1,

We have had the same configuration problem. We have serveral boards with both JTAG header and EPCS header. One for debug and one for EPCS programming. I we could just use one header this would be much easier.

The way to program he EPCS through the JTAG header, we used the Quartus 4.1 programmer.

In Quartus under File there is a menu option Convert Programming files. Open this menu item en then select for JTAG Indirect configuration file.

Then select your EPCS device and add your .sof file and press OK.

Then use the Quartus programmer to open your *.jic file. The programmer now recognises your cyclone device and EPCS device.

It loads a special memory image for the cyclone device to programm your EPCS device. This is all done through the JTAG header.

Good Luck
