=== Inter-core communication ===
Inter-core communication is based on RPMsg framework2framework (please refer to http://omappedia. The adoption of a standardized org/wiki/Category:RPMsg and mainlined protocol improves dramatically the portability and the maintainability of the application codehttps://www.kernel.org/doc/Documentation/rpmsg.txt for more details).
The adoption of a standardized and mainlined protocol improves dramatically the portability and the maintainability of the application code. On Linux kernel, this framework is supported by the kernel 3.10.17_GA – released by Freescale itself along with L3.10.17_1.0.0_IMX6QDLS_BUNDLE BSP – upon which the XELK 2.02.0 is based.
The picture below shows how the system memory is fragmented. The portion of memory used to create a shared area between the two cores – ring buffers – is allocated inside the 256 MByte region used by FreeRTOS.
Please refer to the [[Axel_Embedded_Linux_Kit_(XELK)#Quick_start_guide | XELK Quick Start Guide]] for further details on XELK.
<b>N.B.: </b>this application note has been tested using XELK 2.02.0.
