i.MX6Q uSDHC UHS support

[NithinkumarN]

Hi all,

I'm using i.MX6Q L3.0.35_4.1.0 freescale release in my project.

I need to test UHS-1 Micro SD card in my custom board.

Please let me know is this code release supports this feature?

If not what changes to be done in code as well as board to support this feature.

Thanks and Regards,

Nithin

latest BSP:

Board Support Packages (29)

L3.14.52_1.1.0_MX6QDLSOLO (REV L3.14.52_1.1.0)

Hi Igor,

I need to test UHS-1 DDR50 mode in my board.

Is this support also not present in Linux 3.0.35 kernel of L3.0.35_4.1.0 release?

Thanks and Regards,

Hi Igor,

Is there any patch file present for Linux 3.0.35 to support UHS-1 in it.

Thanks and Regards,
