how to define an array of array in c++

I have this definitions:

typedef uint8_t myType[16];

costexpr myType x0={1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6};
costexpr myType x1={11,12,13,14,15,16,17,18,19,10,11,12,13,14,15,16};
costexpr myType x2={21,22,23,24,25,26,27,28,29,20,21,22,23,24,25,26};

constexpr myType AllX[]={x0,x1,x2};

compiling this in VS 2015, give me this error:

An internal error has occurred in the compiler. 

The intelisense report this error:

    a value of type "const uint8_t *" cannot be used to initialize an entity of type "const uint8_t"    

How can I fix this problem?
