Hi Emmanuel,

We are planning to make a release of the MCC v2.x kernel modules targeting mainline Linux kernel and linux-fslc v4.4 from meta-fsl-arm, roughly by end of Q2. Let me know if you have any questions.

Thanks,

Timesys Support

Hello,

Thanks for the answer. I will be very interested if you have some patches to make tests with MCC V2 on my kernel.

Regards,

Emmanuel

Hi Karina,

It is looking like official support for MCC for mainline Linux will be pushed to Q3, in the meantime, we will share MCC v2.x Linux kernel module sources as-is in the next two weeks that we have tested on a Vybrid platform with Linux v4.1.

Thanks,

Thank timesyssupport for let us know. Waiting for your comments

I have attached mcc-kmod v2.1 sources that we have used with a Vybrid platform running Linux v4.1 and MQX 4.2.0. Note that these sources are provided as-is.

Thanks,

Dear Timesys Support,

some dependencies are missing, for example vf610-mscm.h. I'm unable to find it in any known sources. Is there some public accessible 4.1 repository, which is the right kernel source for compiling your mcc-kmod-2.1.0.1.tar.bz2 ?

Thanks

Edward

Hi Edward,

Sorry for the late response - we don't have a public accessible source repository for this kernel, I have attached the missing source though. Let me know if you need anything else.

Thanks,

Timesys Support,

thanks for these files and sorry for delay. Now it compiles with linker warning for missing symbols from irq-vf610-mscm-ir.c If I replace this irq*.c driver in kernel sources, compiling kernel I get complain about missing #include "irqchip.h". If I replace this include with existing "Linux/irqchip.h", then I get more errors :-(

Dear timesyssupport,

I've been trying to execute a previously working MQX 4.1.1 application on the M4 core of a VF61 module. This application was using MCC v1 and worked properly on a system running linux kernel 3.0.15.

Now I'm using a system running linux kernel 4.1.15 and MCC v1, and trying to run the same MQX 4.1.1 application, but it is not running.

From what I've read above, isn't it possible to run this MQX application the way I'm trying? Do I need to use MCC v2 with linux kernel 4.1?

Thanks in advance.
