do you know if there's a way to initiate fpga (re)configuration cleanly from software/firmware ? (alt_shoot_yourself_in_foot perhaps) --- Quote End --- Most of the Altera designs do this by using the "reconfig_request" PIO. On the Altera boards, this pin is connected to a small design in an on-board Max device. Though I've not tried it, you should be able to do something similar by routing your nConfig pin to another I/O pin on your FPGA.

My confusion over the Flash Programmer User Guide is as much mis-reading as anything - it's not obvious throughout the doc that flashing the bootloader is only needed for CFI Turns out the ability to re-configure "on demand" is present on Stratix/Stratix II/GX chips which have a dedicated remote config control block. Not much help to me with my already manufactured Cyclone II-based design, but hey-ho ..... Hey guys - thanks a LOT for the valuable help ! Alan
