We're working on a custom board derived from Sabre-SDB 6SX rev.c
Sabre has two PHYs. Since oscillators aren't physically present, their clock is provided by ENET_PHY_CLK1 that is ENET_REF_CLK_25M. ENET_REF_CLK_25M is connected to the pad ENET2_RX_CLK.
In fact we measure 50MHz.
Our custom board has one DP83848 as PHY, configured for RMII mode.
Unfortunately ENET2_RX_CLK supplies 25MHz and I don't know why.
We expect 50MHz because settings are equal to the Sabre.
Can anyone help us?
