Vivantec GPU does not respond when iMX6Q operates with single core.

In SABRESDP(iMX6Q) is there a restriction to keep atleaset 2 core active to use GPU ?

I'm running an OpenGL application on core0. If I shutdown core1,core2,core3 GPU does not respond.

Hi, John

     As far as I know, there is no restriction between CORE number and GPU. BTW, when do you shutdown the core1, core2 and core3? Before you lunch GPU app or after? can you try to add "nosmp" or "maxcpus=1" in your uboot command line to let kernel boot up only one core then run the GPU?
