The hummingboard2 is slightly different to the cubox i and to the hummingboard. The GPIO pin info to probe came from solidruns for of u-boot on github. https://github.com/SolidRun/u-boot-imx6/blob/imx6/board/solidrun/mx6_cubox-i... I have tested on a hummingboard-edge witha imx6 solo and 512mb of ram.
