Hi ,

 

I'm trying to get UHS-1 card working on LS1043ardb. I have added the UHS mode in DTB file.

 

After I inserted the card, I could get card attached as SDR104, but looks it will fail at reading SD card and mount the partition.

I could see card in linux, but I'm not able to access the content.
