EGLFS & linuxfb on ubuntu

I have lattepanda v1 and I installed ubuntu server but I cant launch my qml app with 'eglfs' and with 'linuxfb' not show my svg files!!
How to do that????
sudo ./myapp--platform eglfs
output:
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
EGLFS: OpenGL windows cannot be mixed with others.
