Cyclone V won't configure via active serial

I have a Cyclone V design (5CSEBA5) that I am trying to configure using a EPCQ128 device I have created a .sof file that I can load into the FPGA directly (Jtag USB Blaster) and it works fine (...

If you can configure your device via JTAG then there is no problem with any of the device's configuration pins - nCONFIG, nSTATUS, nCE, CONF_DONE, INIT_DONE. So, you can ignore these.

I suspect, like you, you're creating your .jic file incorrectly.

Refer to "how do i create a jtag indirect configuration file (.jic) file with my nios ii hardware and software image? (https://www.altera.com/support/support-resources/knowledge-base/solutions/rd10132010_126.html)".

You can ignore steps 1 to 3 and 11, they're required if you want to boot your Nios software from EPCS too. Start at line 4. Ignore the references to map & hex files in step 12.

You should then be able to select your .jic file from within the Quartus programmer and configure your device.

Cheers,
