I haven't been able to find any matches for this problem in my searching.

I'm using u-boot-bf548-ezkit-uart-2008R1.ldr, and writing it to asynchronous memory using the flash programmer in VisualDSP 5 with no offset. It writes fine, boots fine, and works fine until I try to saveenv. I'm pulling SVN for everything today, so maybe it won't do this once I've built my own files, but I thought it was worth mentioning.

Here's the output from a healthy boot:

Here's a printenv in case it helps:
