Hi,
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.

Hello,
Unfortunately, we cannot help you with this problem since you are using the i.MX8QX, and this product is still in pre-production. For that reason, we do not have any information available and any board to test the problems. I apologize for the inconveniences this could give you.
Best regards,
Diego.

Hi Diego,
I think the problem is only with the pingpong application on the MCUXpresso SDK. because the pingpong binary on the BSP (<build-dir>/tmp/work/imx8qxpmek-poky-linux/imx-m4-demos/2.3.1-r0/deploy-imx-m4-demos/imx8qx_m4_TCM_rpmsg_lite_pingpong_rtos_linux_remote.bin) is working fine.
Could you please share the source code of that binary?

Hello,
Unfortunately, how the board is still in pre-production, we do not have access to the source codes for the i.MX8QX.
I apologize for the inconveniences this could give you.
Best regards,
Diego.
