Hi Lanz,

I have attached you a more detailed description of my configuration solution (including snippets of schematics).

If your FPGA is configured after POR than the EPCQ wiring should be correct.

Verify the map file generated by file convert utility, the firmware have to start immediately after FPGA configuration data.

With the attached procedure my nios system is booting correct from EPCQ.

Does anybody succeed with remote system update and EPCQ? I try the example from alterawiki (http://www.alterawiki.com/wiki/remote_update_for_cyclone_v)

it works just with system console as described. I have to use Nios for the remote update because system console works just with connected JTAG cable :)

I can write the application page address and initiate the reconfiguration from Nios but the application image is not loaded.

best regards

Jens
