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,

    I believe I have got to the bottom of this, and it again comes down to a version mismatch between the binary userspace libraries you have, and the API version of the Mali kernel module you can build.

    I'm afraid the solution is to talk to your silicon provider and request userspace libraries which match the kernel module to which you have access, i.e. r2p0-05rel0 or onwards.

    Sorry I can't be more help, Pete
