stty: /dev/ttyRPMSG0: No such file or directory

Board: STM32MP157F-DK2

Distro: st-image-weston with kernel 5.15.67 (Starter Package)

root@stm32mp1:~# modprobe rpmsg_tty
root@stm32mp1:~# modprobe rpmsg_char
root@stm32mp1:~# lsmod | grep rpm
rpmsg_char             16384  0
rpmsg_tty              16384  0
root@stm32mp1:~# stty -onlcr -echo -F /dev/ttyRPMSG0
stty: /dev/ttyRPMSG0: No such file or directory
 
 

uImage is recompiled and my own dtb file is in use.

Why is the device file not created and how can I achieve the creation?

Thank you.

SOLVED.

I forgot to initialize with

VIRT_UART_Init(&huart0);
