Hi takashi

SION is set by iROM, so yocto may not set it twice.

How did you find that SION is disabled, could you

say procedure ? Had you read iomux register ?

Also had you included uSDHC driver in linux build ?

Best regards

Hi chip

Do not verify that SION is disable.

There was a terminal which is set bit of SION explicitly pinctrl setting of "imx6qdl.dtsi",

So I think other terminals is SION = disable.

Thanks,

Best Regards.

Hi chip

Thankyou for your replay.

Do not hit the Enable explicitly in "imx6qdl.dtsi", etc..

As to Enable, do I need to modify the BSP?

Or consideration  is not required in particular?

Thank you,

Best Regards.

Hi takashi

yes I think you can explicitly enable

SION bit in BSP (modify the BSP).
