Hi Kerri,

Thanks for the help. I contacted a local FAE today and he had me zip my project to move it up the Altera line.

In the meantime we're going to try a less sexy solution and wire up a lpm_fifo to a normal memory port and IRQ on AlmostFull.

I really wanted a more elegant solution like Streaming DMA or Master Port, but if it works... I did have to give up 1K of instructions cache for the fifo, and it's not working yet either. Maybe in a day or two I'll know. (just built it a few hours ago - need to modify a little firmware to support it)

Maybe someone in Altera will come through with a fix for the MasterPort project I sent in.
