Maybe the '''GPU reserved memory''' area in the kernel device tree is not ''aligned'' with the board DDR memory size. Have a look at the "gpu_reserved" entry in the kernel device tree, and update it if necessary. | Maybe the '''GPU reserved memory''' area in the kernel device tree is not ''aligned'' with the board DDR memory size.
