Your basic procedure sounds okay.

Are the MSEL pins on the FGPA set correctly for AS configuration? What about other configuration related pins such as nConfig? Have you read the relevant details in the cyclone ii manual (http://www.altera.com/literature/hb/cyc2/cyc2_cii51013.pdf)?

Are you 100% sure both the FGPA configuration and Nios code fail to load? You mention it should flash an LED, but do you expect the LED to flash independent of Nios booting properly? Things such as the reset vector and BSP settings would have no effect on whether the FGPA itself configures correctly but could effect Nios booting.
