Hi,
My customer uses AM3874 with DDR3 memory. And my customer is confirming the feature of autoleveling for DDR3.
But they can't read DDR3 memory correctly with autoleveling in their system. If they does not use the autoleveling feature,
they can read DDR3 memory correctly.
The following is my customer's register setting for DDR3.
DDR2/DDR3 Memory Controller Registers
○RDWR_LVL_RMP_CTRL(D8h ) bit31:RDWRLVL_EN = 1
○RWLCR(DCh) bit31:RDWRLVLFULL_START = 1
Is the above register setting enough for DDR3 autoleveling feature? Also is the above setting correct for autoleveling?
If you find something wrong, please let me know.
Best regards,
Michi
