Ok, this really points to the hardware reset at the "source" of the
problem, either inside the PHY or the MPC8260.
- Once again: After reset, the PHY has at least 5 seconds time for
auto-negotiation, before the ethernet traffic starts? This should be
ensured with the download time anyway...
- Can you possibly send me the source of the ethernet driver just to
double check, that everything is all right there?
wkr,
Thomas.
