Shouldn't M02_AXI > 7, your tutorial said 7 flags error.

that's true, the version of my Vivado is 2016.4, in which width of 7 works. In the latest version there is a constraint of width, expected to be greater than 12. you need to set M02_AXI to 12 here (as a consequence partial of the address space is wasted). I will change this document and the dts file later.
