[imx8mp]Weston-rdp screen share issue

I have imx8m board which has one display connected. and i want to share custom board display screen to any host machine(in my case it it Linux system)

For that i used to weston-rdp service for sharing screen and below configuration i have done in bot side client and host.

In yocto add below lines into the weston bb file “weston_10*.imx.bb” to enable freerdp support.

DEPENDS += "freerdp"

EXTRA_OEMESON += "-Dbackend-rdp=true"

On client side: Add below module into the /etc/xdg/weston/weston.ini file.

[core]
modules=screen-share.so

Add below command into the /etc/xdg/weston/weston.ini file

command=@bindir@/weston --no-config –backend=rdp-backend.so

Generate TLS certificate/key.

Modify ExecStart command into the /lib/systemd/system/weston.service file.

ExecStart=/usr/bin/weston --backend=rdp-backend.so –rdp-tls- cert=/home/root/server.crt --rdp-tls-key=/home/root/server.key

restart the weston service.

  1. On Host side:-

Run xfreerdp with client ip address and display resolution.

xfreerdp /v:192.168.200.59 /size:800x480

When I restart weston service after all changes the service not started and weston not created socket into the /run/user/0/ location. this issue created when i add “–backend=rdp-backend.so” into the service file.

In normal state without --backend=rdp-backend.so the weston created socket into the /run/user/0/ location. Why weston failed in when i add rdp-backend.so in weston.service file ? can someone help me ?
