Dear sir,

 

We found some UHS card cannot work in SDR104 on imx8-evk. Sometimes tuning failed, sometimes not command response from card after tuing. All card work OK in high speed mode. We want to know your UHS card test results on imx8-evk.

Below information is from TI for your reference. Do you have similar testing information to share?
