</span>I can confirm it is a board level issue: I had the pleasure of playing<br>
with Steve's board as well as my own, and as he reported, one of my<br>
working SDs also worked on his board. My experience is not as bad, but<br>
out of my sizable collection, only two uSD cards are accepted by the<br>
bootrom.<br>
