Tutorial vadd on sw_emu using xilinx_u250_gen3x16_xdma_3_1_202020_1 caused error in ./app.exe

[danna2019]

On the tutorial "Getting Started: Part4/Instructions for the Alveo U200 platform", I'd like to use Alveo U250, installed some platform dependent files on "/opt/xilinx/platforms/xilinx_u250_gen3x16_xdma_3_1_202020_1", and "Vitis-Tutorials/Getting_Started/Vitis/example/src/u200.conf" to u250.conf as below:

platform=xilinx_u250_gen3x16_xdma_3_1_202020_1
debug=1
save-temps=1

[connectivity]
nk=vadd:1:vadd_1
sp=vadd_1.in1:DDR[1]
sp=vadd_1.in2:DDR[2]
sp=vadd_1.out:DDR[1]

[profile]
data=all:all:all

and some commands following the instruction as:

$ g++ -Wall -g -std=c++11 ../../src/host.cpp -o app.exe -I${XILINX_XRT}/include/ -L${XILINX_XRT}/lib/ -lOpenCL -lpthread -lrt -lstdc++
$ emconfigutil --platform xilinx_u250_gen3x16_xdma_3_1_202020_1 --nd 1
$ v++ -c -t sw_emu --config ../../src/u250.cfg -k vadd -I../../src ../../src/vadd.cpp -o vadd.xo
$ v++ -l -t sw_emu --config ../../src/u250.cfg ./vadd.xo -o vadd.xclbin

after the instruction, I've try to "./app.exe". Unfortunately it's occurred 'Segmentation fault'.

$ export XCL_EMULATION_MODE=sw_emu
$ ./app.exe 
INFO: Found Xilinx Platform
INFO: Loading 'vadd.xclbin'
terminate called after throwing an instance of '__gnu_cxx::recursive_init_error'
  what():  std::exception
Segmentation fault (core dumped)

How I should be?

Self solved.
