Could you post the link to the TI thread where this is discussed? Who is actually involved in choosing parts for the BBB and in adding layout changes? I offer sending one of mine BBBs to someone involved in the BBB developing process for evaluation purposes if requested.
I mean this behavior is pretty annoying, this morning it took me almost 20 attempts to get one BBB running with ethernet. Furthermore I assume that many posts in forums related to non-working BBB ethernet may be related to this problem. Am Dienstag, 19.
