I found the tarball /opt/freescale/pkgs/gpu-viv-bin-mx6q-12.09.01.tar.gz
but there are some prebuild library and executive bin file
when I run the viv demo, there is nothing output to the lvds screen
but I haven't got any error print on the serial terminal.
Maybe the minigui has occupy the framebuffer which is the default output of the viv demo !?
where can I get the viv demo source?
