State of iMX28 in Linux 3.x Kernels?

[mwill]

Greetings all,

Im having a bunch of performance issues using recent 3.x linux kernels (slow uSD, USB, linuxfb, etc performance).

It also appears cpufreq, powersaving, etc functions are not availiable.

Is there any Freescale support/maintenance of the iMX28 in the 3.x kernels, or would i be better off moving back to 2.6.35 with related Freescale patches?

Thanks in advance,

Mark,

Which kernel version did you use? It would be nice if you could report the issues you noticed in the linux-arm-kernel mailing list, so that people could be aware of them and eventually fix them.

I'm using 3.17.4, and have tried a few previous 3.x versions as well.

By "people" im guessing you mean the community, and not Freescale?

[fabio_estevam]

Yes, I mean the community. If you report the issues in details in the mailing lists, then maybe someone can try to fix them.

Hi Mark

I think you are right, since officially supported only releases located

on Freescale i.MX product web pages, like below

i.MX28 Evaluation Kit|Freescale

Best regards

So does that mean Freescale has stopped maintaining Linux support for the iMX2x?
