Hi.
I have a question about ODT setting for DQS in i.MX6SDL.
First, refer to 36.4.358 Pad Control Register (IOMUXC_SW_PAD_CTL_PAD_DRAM_SDQS0_P) in IMX6DQRM_Rev.1.
===
On Die Termination Field
Select one of next values for pad: DRAM_SDQS0.
000 DISABLED— Disabled
001 120_OHM— 120 Ohm ODT
010 60_OHM— 60 Ohm ODT
011 40_OHM— 40 Ohm ODT
100 30_OHM— 30 Ohm ODT
101 24_OHM— 24 Ohm ODT
110 20_OHM— 20 Ohm ODT
111 17_OHM— 17 Ohm ODT
===
Next, refer 37.4.299 Pad Control Register (IOMUXC_SW_PAD_CTL_PAD_DRAM_SDQS0_P) in IMX6SDLRM_Rev.1.
===
On Die Termination Field
Read Only Field
The value of this field is fixed and cannot be changed.
000 DISABLED— Disabled

[Question]
I seemed that SDQS can't set ODT in i.MX6SDL.
Is there any way of setting ODT of SDQS or Not?
Best Regards,
Keita

Generally it is recommended to use only MMDC_MPODTCTRL register to configure ODT.
