i.MX6Q uSDHC UHS support

NithinkumarN — Wed, 30 Mar 2016 09:51:21 GMT

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

Hi Nithin

I am afraid this release does not support UHS, suggest to try

latest BSP:

Board Support Packages (29)

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

Best regards

igor

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,

Nithin

Hi Igor,

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

Thanks and Regards,
