Hello Community

 

I have some quetions about i.MX6 SD & SDIO

 

1)Is it L3.0.35_4.1.0 support SD3.0 UHS-I mode?

In i.MX_6Dual6Quad_SABRE-AI_Linux_Release_Notes for L3.0.35_4.1.0, there is description as bellow:

But I did a test with an UHS-I SD card on i.mx6qsabreauto board with BSP 3.0.35_4.1.0,the card did not enter

USH-I mode(I am sure the related configs are right).On the otherhand,the Yocto BSP is OK.

 

2)According to the snapshot above, L3.0.35_4.1.0 does not support SDIO3.0 specification, is it right?
