Hi,
I am trying to determine the seed values for mDDR.The AM335x EMIF configuration tips mention several ratio seed values to be determined using the Ratio Seed spreadsheet.
However this spreadsheet gives me values only for WR_DQS_SLAVE_RATIO, RD_DQS_SLAVE_RATIO and FIFO_WE_SLAVE_RATIO.
The EMIF configuration tips describe registers for DATAx_PHY_RD_DQS_SLAVE_RATIO, DATAx_PHY_FIFO_WE_SLAVE_RATIO, DATAx_PHY_WR_DQS_SLAVE_RATIO, DATAx_PHY_WR_DATA_SLAVE_RATIO and CMDx_PHY_CTRL_SLAVE_RATIO.
The bootloader code shows how to map most of the values into the registers but CMDx_PHY_CTRL_SLAVE_RATIO is unclear. What do I need to write into these registers for mDDR?
