I am using OSTL 4.1.1 and build DISTRO=openstlinux-weston MACHINE=stm32mp15-disco. I am using STM32MP157F-DK2. Found that rpmsg_tty build as dyanamic module. I have loaded rpmsg_tty.ko with modprobe but found that node entries are not getting created in /dev

Hello @GChin.1 ,
Are you sure you have a firmware running on Cortex M4 that initalize the RPMSG communication ?
If not, please follow this wiki to make it work :
and then
This last one show you the OpenAMP_TTY_Echo example that initialize this coprocessor communication.
Kind regards,
Erwan.
