I'm trying to use the SATA devices in the MPC8379 evalutaion board. I'm having problems while updating the SRDS registers so it's programmed to use SATA interface.
I'm trying to set the following values:
SRDSCR0: 0x1100CC30
SRDSCR1: 0x00000040
SRDSCR2: 0x00001414
SRDSCR3: 0x15150528
SRDSCR4: 0x40000808
However this registers are always with the reset values. Should I do something else before being able to edit those registers?
Look at the Section 19.4 of the MPC8379 Reference Manual. This Section contains command sequence for SerDes and PHY initialization and Reset.
Test your board using this command sequence.
Have a great day,
Pavel

Pavel,
thanks for your response. This is exactly the sequence I'm following but still SATA device's are not working. I'm following the code I'm using in the MPC8315, adding the initialization of the SerDes PHY.
Any clue in what the problem may be?
