Thank all for your help with both platforms. I found the value to boot!
Great!

The BMS was high before, so BCSR4 was 86, but for low boot it needs to be 82.
Oddly, changing the SW4.5 did not seem to change this(?) I was able to write it from u-boot
=> mw.b f8000004 82
And that did the trick!
Thank you all. Any ideas why the switch is not working? Currently I have to turn the board on, issue the above instruction to set low boot mode, then reset. I should be able to power off/on and boot into low memory. Any guesses what I am missing?
Sorry, no idea. Perhaps its a change between the E and the EA board.
Let us know if you figure it out :)
