I am working with the rpmsg_lite_str_echo_rtos_imxcm4 and having some mishaps.
Following the readme.txt from the example, i am able to load the .bin to the M4 core.
(although is weird to me why core stack is not at 0x007e0000)
But i am not able to see the /dev/ttyRPMSG30 device driver supposed to be created when the imx_rpmsg_tty kernel module is loaded. Thus failing when:
Doing some research i found that imx8mm-navq.dtb disables rpmsg
could that be the reason?
Thanks in advance
what m4 side log shows? what kernel verison are u using? Seems virtio channel not created, if ttyRPMSG not created after you insmod imx_rpmsg_tty.ko
