Hi,

 

I am Working on iMX6ul using Linux.

SD card has successfully interface on uSDHC1. I can successfully boot and also save data to SD card.

Now I have to change SD pinmux as per below.

SD1_DATA0USDHC2_DATA0GPIO4_21
SD1_DATA1USDHC2_DATA1GPIO4_22
SD1_DATA2USDHC2_DATA2GPIO4_23
SD1_DATA3USDHC2_DATA3GPIO4_24
SD1_CMDUSDHC2_CMDGPIO4_20
SD1_CLKUSDHC2_CLKGPIO4_19

 

What change need in Linux kernel file .dtsi and uboot  file to interface uSD card as above configuration?

 

Thanks,
