Actually, I get the "nStatus asserted by an external device" bit set in the reconfig trigger source even when booting from a fresh factory image (just overwrote all flash with just one factory image). According to the Altera docs, this should not be happening. I was hoping to use this to detect errors in the application reconfig, but if it is set at factory startup I will have to find another way.

Or are you and I finding similar experiences: Cyclone III and Remote Update have problems working together, or, something there is hidden that we're both not doing. I believe the latter because we
both could be missing it in the docs. For me it wasn't a "try 'n post here" situation - I've been working on this on and off for a couple of weeks. But I fought SGDMA and TSE issues for over a week only find out the image I programmed into flash was corrupt (despite a correct TCP download!). Once I knew the image was right, I knew I had remote update problems.
What I did that simplified things is I added a function that copied EPCS from factory (0) to update (0x100000), compare them with a read and memcmp, and then did a Remote Update at 0x10000>>2. This way I knew the second image was good. It does reboot (if really into the second configuration I can't say) and the registers never said it was an application/update.
