Hi,

I'm using i.MX6UL processor. I want to enable write protection for the usdhc1 [mmc].

But setting the register MX6UL_PAD_CSI_DATA04__USDHC1_WP to proper value. but still seeing write protection is not enabled for the sd card connected.

I even tried adding following line to DTS file:

&usdhc1 {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_usdhc1>;
   cd-gpios = <&gpio2 21 0>;
   wp-gpios = <&gpio4 25 0>;
   no-1-8-v;
   keep-power-in-suspend;
   enable-sdio-wakeup;
   status = "okay";
};

But still it didnt work.

Am I missing any setting further? Can you please help me out.

BR,

Anantha R
