Please refer to the following

usb issue with i.MX28 with Linux 3.10.32

Fabio recommends to apply to more recent kernels, such as 4.1, for example.

Have a great day,
Yuri

Hi Yuri,

Just to clarify: the recommendation for going to 4.1 was for mx28.

Not sure which SoC is being treated in this thread though.

How do you do for the devices tree? copy over to the 3.14.28 from 3.10.17 or merge to 3.14.28 from 3.10.17.

If you just copy over, please merge again and test.

cause the device tree changes are related the driver read it and how to use it?

Different linux version will have different behavior.

Please do merge.

Sorry for my misunderstanding.
I tried demo image 3.14.28 on my SDP - USB mass storage device is working.

If You built own image, please check kernel configuration. Refer to section 41.2.3

(Menu Configuration Options) of "i.MX_6_Linux_Reference_Manual.pdf".

Yuri
