AT91SAM9G20-EK Evaluation Board User Guide
Ethernet
Miscellaneous
RMII is the factory default mode. To evaluate the MII mode, the user has to unsolder R49, R50, R127
and close S7 and S8. When the RMII mode is used, the user can use the specific MII signals as PIO, but
the following resistors must be unsoldered (R119 to R126).
Note that, by default, resistors R112 and R120 are not populated in order to avoid contention between
the MII signals and the SD Card slot J35. If the Ethernet MII mode is implemented on the board, then you
must not insert any card into slot J35. Otherwise, signal conflicts could occur and damage both the
Ethernet controller and the SD Card.
Refer to “Board Layout - Top View” in
Section 5.1 ”Schematics”
for the PIO Usage.
