Different results between EMU-HW and EMU-SW

I'm implementing a simple memory copy kernel in SDAccel, the kernel is written in HLS.

Attached is the kernel file. 

In SDAccel EMU-SW simulation, I can see data being copied correctly (host will copy the buffer back from device memory to host memory to check the data). However, in EMU-HW, the destination buffer shows all data is 0.

I wonder if something is wrong in the code? Could anyone help? Thanks!

Please refer to "Waveform-Based Kernel Debugging" in UG1281(SDAcel debugging guide) to debug it in HW-EMU mode.
