Hi,
On TMDXEVM6678L it appears I have DDR3 working with partial automatic leveling.
I believe it more reliable to add Incremental Leveling, so I added 3 lines of code from SPRABL2 Example 20.
RDWR_LVL_RMP_WIN = 0x00000502;
RDWR_LVL_RMP_CTRL = 0x80000300;
RDWR_LVL_CTRL = 0xFF000900;
How can I verify Incremental Leveling is operating?
I read the RD_DQS_SLAVE_RATIO field in DDR3_CONFIG_REG_23, but it’s not changing from the initial value. Should it? Is there another way I should verify Incremental Leveling?
