Ah - yes, different point, since I have
AT91F_MCI_CfgPIO();
AT91F_MCI_CfgPMC();
For BWCT boards.
That fits with Warners assumtion of miss-/nonconfigured GPIO.
In the same manner he is probably right about the PHY, since a non
matching rlphy should result in ukphy to match.
Not shure about bootspi, but depending on the configuration it might
ignore a MDIO Problem with the PHY.
