hi, I'm currently using the cyclone ii (ep2c20f484c7) fpga, and i want to do the active serial programming. i configure the device for active serial programming as the following way mode: Active Serial Programming Device: EPCS16 (But it should be EPCS4 nah?) when i change the device from EPCS16 to EPCS4 and adding the .pof file it is not uploading to the eeprom.

Is the FPGA configured correctly for AS mode? Check how the MSEL pins are configured.
Actually i couldn't find the configuration switch on my fpga. :(

Do you have a link to the schematic of your board? The configuration options are usally some pins on the fpga device. Duke
I have uploaded the schematics.

The MSEL pins are both connected with GND. Look at the chip documents to see what that means. Duke

which means i can do the active serial programming without configuring the msel pin, because it is already connected to ground.
