vectorArray not work in opengles 2.0?

I test the moving in vertex shader,but it seems work in opengles 3.0 but fail in opengles 2.0,this is a bug?

Code (CSharp):

1. uniform float4 _Points[250];  
2.  
3.             v2f vert (appdata v)
4.             {
5.                 v2f o;
6.                      float4 pos=_Points[100];  
7. }

 

Seems like a lot more data than possible in OpenGL ES 2.0. I'd say, check the specifications...

 

run in dx9,console not show error,seems the shader is correct
