Unable to run multicore example on MCUXpresso SDK

        I am trying to run the ping-pong application provided on the MCUXPresso SDK  (<SDK>/boards/mekmimx8qx/multicore_examples/rpmsg_lite_pingpong_rtos) on imx8qxp. in order to do that, I compiled to make m4_image binary of rpmsg_lite_pingpong_rtos application. and I made flash.bin by following command using imx-mkimage.


 mkimage_imx8 -soc QX -rev B0 -append ahab-container.img -c -scfw scfw_tcm.bin -m4 m4_image.bin 0 0x34FE0000 -ap u-boot-atf.bin a35 0x80000000  -out  flash.bin


Then flashed to SD card using dd command.  console one for A-35 and other for M4, both are working fine. after A-35 booted (linux), I installed the imx_rpmsg_pingpong.ko file using insmod but there is no inter-communication between the two core.

could you please help on this.
