VTA on DE10pro Board returns Zeros

Hello TVM/VTA experts,

I am currently working on bring up VTA on an Intel De10pro FPGA board. After dealing for numbers of issues, finally I got vta kind of running on de10pro board. However, when I ran TVM/VTA tutorials - vta_get_started.py and matrix_multiply.py, once VTA done bit set in control register within fpga, the tvm/rpc server copied all zeros value back to tvm client, and the these two python app report result data mismatching.

Has anyone on the forum had same experience as me? Or any comment or suggestion is apricated!

Thanks in advance!
