I haven't thought of performing those tests. Are > there specific tests I can enable in the U-Boot environment for that? Perhaps the memory tests from the POST infrastructure. But from my experience a realworld application running under Linux is a good test. For example compiling a Linux kernel in a loop. Perhaps mounted via NFS. Something like this should fail at some time when SDRAM related problems exist. > We have been using a couple of these boards extensively and in some pretty > loaded configurations.

That's good. Which OS was used here? Linux? But Jerry's note about x-raying the problematic board is a good idea.
