AM335x Using the Ratio Seed spreadsheet for DDR3

$
0
0

If the PHY_INVERT_CLKOUT is 1, all the calculation values seem true value, but the CMDx_PHY_CTRL_SLAVE_RATIO shows "100" which is beyond "80h" as the upper limit of the register value. If the PHY_INVERT_CLKOUT is 0, the WR DQS value on Byte 1 shows "FFFFFFFFFD" and the DATAx_PHY_WR DQS_SLAVE_RATIO shows 0. For the PHY_INVERT_CLKOUT, which value of 1 or 0 should be used?

Best regards,

Daisuke
