Does Freescale iMX6 Linux BSP support openAMP?

mileswang — Wed, 16 Sep 2015 10:19:55 GMT

Hello,

I want to run openAMP on iMX6sx-sdb. ARM A9 core runs Linux and M4 core runs vxWorks.

The communication between A9 and M4 uses openAMP framework.

Does Freescale iMX6 Linux BSP (Yocto project) support openAMP?

Thanks,

Miles

Hello,

I read the attached Linux Manual Chapter 53 and knew that Freescale’s solution to the multi-core architecture with different OSs is a multi-core communication (MCC) protocol. MCC is different from openAMP.

The key components and capabilities provided by the OpenAMP Framework include remoteproc and RPMsg.

So Freescale Linux doesn't support openAMP. Right?

Best regards,

Miles

Hi Petr,

Can the RPMSG be used for i.MX6Q? I would like to configure it in AMP mode.

3 Cores run Linux and the fourth will run bare-metal.

Is there any example code?

Thanks,

Tarek
