Once the power to the SDRAM and SoC is stable, the DDR PHY must be reset and initialized before normal traffic can commence. Once the initialization has completed, the DDR PHY asserts the dfi_init_complete signal to notify the DDR controller that the PHY and SDRAM are ready to accept commands.
The procedure to initialize the DDR PHY is as follows:
For information about the DDR controller initialization, see Section 8.2.3.6.9.
