HOW TO MAKE LOW FOR WRITE PROTECT PIN IMX6 SOLO LITE PROCESSOR

[sivakumarganesa]

Hi ,

In our board we are using the manufacturing  mode for booting from the SD1 slot. In my design having the micro SD slot. So it doesn't have the write protect pin from the micro SD connector. So i didn't use the write protect pin in the processor pin itself. Because of this problem i couldn't able to make the partition in micro SD card while running the kernal.

Please help me to make low for  write protect pin in sololite processor by using the software approach.

Is there any changes required in uboot code to make wirte protect low.?

Thanks,

Sivakumar

Hi sivakumar

I think one can look at WP,CD handling at

MX53UG sect.15.2.4 Setting Up Card Detection

for new kernels at

..boot/dts/imx6sl-evk-common.dtsi for "wp-gpios"
