Dear team,

 

I would like to ask about SPEED and SRE bit field setting of i.MX6SoloLite IOMUXC_SW_PAD_CTL_PAD_xxx register.

My customer is facing the issue that they sometimes saw CRC error on SD Card data transfer between i.MX6SoloLite. And they think SPPED and SRE setting of IOMUXC_SW_PAD_CTL_PAD_xxx registers might affect it.

(1)

What values should be set to SPEED bit field of IOMUXC_SW_PAD_CTL_PAD_xxx registers?

The customer is using SD Card interface of i.MX6SL as SDR-50.

(2)

What values should be set into SRE field of IOMUXC_SW_PAD_CTL_PAD_xxx registers for related pads? And could you show me what is changed actually by the setting of SRE bit?

 

Thanks,

Miyamoto
