- Six boards work, one board fails.
- SDRAM chips re-balled on the failing board.
- SDRAM failing.
That sounds like a hardware/assembly problem to me. My bet is a solder problem. Have you (can you) x-ray the chips and verify the SDRAM soldering is OK?
That was my initial hunch simply because of the 6 working boards. Our hardware designer took the board in for x-ray this morning to see if there is an issue there. If that is the problem, then we are set - though I still plan to run some extensive diagnostics on the memory just to be sure.
Good to hear that someone has the same hunch as I did!
