About Hold Delay of QuadSPI configuration parameters

[goto11]

Hello,

Isn't the Hold Delay of 6.6.6.3 (QuadSPI configuration parameters) in the i.MX 7Dual Applications Processor Reference Manual the TDH setting of 10.2.14.3 (QuadSPIx_FLSHCR)?

If not TDH, where can I find a description of Hold Delay?

best regards

Hello,

   Hold Delay for quarter cycle is used for DDR mode.

Hello,

Does Hold Delay mean that the quarter cycle is used in DDR mode, which means that it is set to the TDH setting "01" of 10.2.14.3 (QuadSPIx_FLSHCR)?

If so, should it be set to "01" in DDR mode (DDR_EN = 1)?

Regards,
Goto

Hello,

    Recommended QuadSPIx_FLSHCR [TDH] settings [should be set to 01
in DDR mode (DDR_EN=1) and set to 00 in SDR mode (DDR_EN=0)]  corresponds
QuadSPI configuration boot parameter Hold Delay.
