Cyclone EPCS1 programming...

Is there anything special to EPCS programming?

Configuring my Cyclone board through JTAG directly works fine...but when using EPCS1 device in AS mode I see thaat the FPGA is running (external VGA monitor syncing) but see no output.

Do I need to manually add ROM files I use in my design?

Or does AS configuration with EPCS devices not support initialisation if BRAM at all????

Solution was simple..

JTAG programming does a proper reset whereas configuration from EPCS doesn't...so using now "locked" signal from PLL to generate Z80 CPU core reset (o;

use the fast down clk.(eg:40m)
