ZynqMP: GPU gives wrong result when using it together with VCU

Jump to solution

Hi,

I'm working on a custom board with ZynqMP SOC. I used Mali GPU to do some calculations and it works well. But when I add VCU into the Vivado project and device tree, the GPU gives wrong result with no MaliSDK interface error.

I'm sure that there's nothing to do with VCU driver because it goes the same without VCU driver installed.

My question is if GPU is compatible with VCU?

I find the reason. The address of framebuffer(/dev/fb0) is changed when VCU is added. So I fetched result from a wrong place.
