Sharc memory access using Index Register

I have an issue while trying to access the Sharc memory using the index register in this particular way.

.section/dm seg_dmda;


.var Test[2] = 100, 200;



.section/pm seg_pmco;

     i7 = 0;

     r1 = dm(Test,i7);

     i7 = 1;

     r2 = dm(Test,i7);





The above code works fine on the simulator. But it does not work, while connected to the dsp.

( I think the above code was working on the old 21065L Sharc processor, but not on the later SHARC's. )


I would be really thankful if anybody could explain why this is happening.

I would also like to know why this code is working on the simulator but not on the dsp.
