Hi all,


 I am trying to run the ping-pong application on imx8qxp with core A35 run linux version 4.9.88-05083 and core M4 run RTOS version 2.5.1. 

In Uboot console I implement following below step:

- fatload mmc 1:1 0x88000000 rpmsg_lite_pingpong_rtos_linux_remote.bin

- dcache flush

- bootaux 0x88000000

(it shows log:     RPMSG Ping-Pong FreeRTOS RTOS API Demo...

                          RPMSG Share Base Addr is 0x90010000)

- boot (to boot linux console)

In Linux console I insert module:

- insmod imx_rpmsg_tty.ko

- insmod imx_rpmsg_pingpong.ko

And run 'ls /dev' command. but I don't see " ttyRPMSG " device file in "dev" folder.

Could anyone has any suggestion to fix this Issue?

Many Thanks,
