Hello! I'm working on an I. MX93 intercore communication function test encountered a problem.
First of all, both the A and M cores have started up normally. The SDK used by the M core is version 2.14.2, using the demo ：rpmsg_lite_str_echo_rtos . The device tree file that A core loads is imx93-11x11-evk-rpmsg.dtb. I'm following orders from A-core, but M-core is not responding, it didn't print out"Hello World".
A Core command:
- # modprobe imx_rpmsg_tty
Then the log message of A core is :
[ 17.843403] imx_rpmsg_tty virtio1.rpmsg-virtual-tty-channel.-1.30: new channel: 0x400 -> 0x1e!
[ 17.843584] Install rpmsg tty driver!
the log message of M core is:
RPMSG String Echo FreeRTOS RTOS API demo...
Nameservice sent, ready for incoming messages. . .
Please，Can you tell me what the problem is?
