Hello

 

You have the MX6ULL don´t have GPU and 512 MB of RAM, you need at least 1GB to run the demo.

As i have imx6ullevk, and it has 4GB DDR3 ram
https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-...
how can i make use of 4GB to make this demo run?
I have tried changing the memory size in kernel dtb, kernel boot parameters, u-boot configs e.g. in <u-boot>/include/configs/mx6ullevk.h file changing the size of PHYS_SDRAM_SIZE to SZ_1G, but nothing worked for me so far.
