Hello,

Please check this post.

I config with your reply to kernel dts,but I can’t find the sdcard info when system power up.

Looks like the card is not getting detect at all.

  1. Are you sure the power source is stable?

  2. Please check if the device tree is really as your expectation by checking /proc/device-tree.

Now i can find sd card device ,but can’t use. This is error message.

Hi,
It can’t detect sd card when insert sd power on. But plug in and out sd cart , it can detect sd card.

And your board schematic please?

We are checked, this problem is related with tf power supply. Thanks.
