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?
