If you have eMMC and a SD card and try to re-size the file system it will not work. You have to unplug one of them.
I thought the switch on the side would say what one I wanted to use. But have to unplug one and then can re-size the file system then.
I got the Odroid-XU4 and it works real good on mine. No problems. I am very impressed with this max2play.
