CAN BUS iMX8QXP MEK in Android Automotive

Hi,

I'm trying to use the can bus interfaces in Android Automotive but for now, isn't possible.

I have enabled flexcan driver in the kernel configuration using menuconfig.
After this, in the adb logcat, i see the vcan and can driver fet up in boot but anything about can0,can1 and can2.

As I have seen in other forum posts, the can bus resources are assigned to the m4 processor. So I've tried to delete the m4 processor partition using a custom scfw but I haven't noticed any change.

In fact, I am making use of the android automotive mek_8q_car2 image and when I use the custom scfw without the m4 partition, I still see the power switch on the m4 processor when I understand that it should not be.

So my question is:

Is it possible to make use of CAN interfaces from cortex A in android automotive?

If this is not possible, Android Automotive could read the canbus data from the M4 processor and interpret it in the Cortex A.

Thank you very much

Hello esqui2002,

A1. No, because CAN it's not implemented in android just for the M4.

A2. Yes, you can send a message fro M4 to cortex A
