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.

    Hi James,

    can you do:

    ls -l /lib/gles20/

    to check the file sizes and types of all the libraries?

    Also, can you check:


    ls -l /dev/fb
    ls -l /dev/ump


    to be sure they both exist and have the right access permissions?

    Do you know whether the driver libraries you have are the same version as the kernel module? The kernel module reports as r2p2 (which is v8). You can check what version the driver libraries are with something like:


    strings /lib/gles20/libMali.so | grep r2p


    should show the version string for the binary libraries. It should match (i.e. r2p2), if not you may need to contact your silicon supplier for updated driver libraries.

    Cheers, Pete
