Problem: "Kernel attempting to read an un-initialized memory location ::0x0"

When I use SDx(2018.2) to run the example instance(Xilinx/SDAccel_Examples/getting_started/rtl_kernel/rtl_vadd, https://github.com/Xilinx/SDAccel_Examples/tree/master/getting_started/rtl_kernel/rtl_vadd), the command line shows that "Kernel attempting to read an un-initialized memory location ::0x0" and "Kernel attempting to read an un-initialized memory location ::0x400".

Does it mean that the generated arrays wasn't passed into the global memory? So the memory was un-initialized?

Thanks

emmm, in fact the link is the same question I post accidently.
Anyway,
The thing is this:
when I was in the /SDAccel_Exampls/getting_started/rtl_kernel/rtl_vadd/ , I input"make check TARGETS=hw_emu DEVICES=xilinx:adm-pcie-8k5:2ddr:3.3", it just shows that "read an un-initialized memory location::0x0"
where did I do wrong? Should I package the RTL block into Vivado IP fisrt?
Thanks.
