Dear all,

I'm trying to build linux Mali200 driver in arm system.
I build mali.ko and insert it success in linux.
The attachment is log when I insert module.
It always told me "Mali device driver r2p2-03rel0 loaded".

Would you please tell me how could I make sure the driver work success?
Because I try to run the SimpleProject.
It always get the error message "Error: No EGL Display available at src/egl_runtime.c:64"

thanks.

    The following is the imformation from my target.

    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib/gles11:/lib/gles20;/lib/openvg

    Maybe is the version is wrong.
    In your imformation it should match r2p2, but my version is r2p0.
    I think I will try to build mali.ko (r2p0).
