window. The typical value of tDQSQ is 0.85ns (max) and 1ns (max) for tQHS at 200MB/s.
GPMI will sample DQ[7:0] at both rising and falling edge of an delayed DQS signal, which can
be provided by an internal DPLL. The delay value can be controlled by GPMI register
GPMI_READ_DDR_DLL_CTRL.SLV_DLY_TARGET(see the GPMI chapter of the i.MX
6Solo/6DualLite reference manual). Generally, the typical delay value of this register is equal
to 0x7 which means 1/4 clock cycle delay expected. But if the board delay is big enough and
cannot be ignored, the delay value should be made larger to compensate the board delay.
GPMI’s Sync Mode output timing could be controlled by module’s internal registers, say
HW_GPMI_TIMING2_CE_DELAY, HW_GPMI_TIMING_PREAMBLE_DELAY, and
HW_GPMI_TIMING2_POST_DELAY. This AC timing depends on these registers’ settings. In the above table, we
use CE_DELAY/PRE_DELAY/POST_DELAY to represent each of these settings.
