CVX Status: Infeasible

What should I do when the status is ‘Infeasible’ in cvx?
The code as following:

    cvx_begin
        variable  u(Q,1) ;
        variables gama(Q,1) g;
        psi=J*G1*B;
        Y=J*y;
        VV=J*vec(eye(m));
        D=Y-VV;
minimize (g);
subject to
        G*u<=gama;
        sum(gama)<=g;        
        norm(D-psi*u)<= beta1;
cvx_end 

thank you!

All except for section 1 applies to CVX. https://yalmip.github.io/debugginginfeasible/

thank you very much!
