MMAP issue for vector addition example

[RatkoFri]

Which tutorial are you running? https://github.com/Xilinx/Vitis-Tutorials/blob/2023.1/Getting_Started/Vitis/Part4-data_center.md

Describe the issue After running software emulation for alveo u280 i get following issue:

[user@host$ ./app.exe 
argc = 1
argv[0] = ./app.exe
Open the device0
Load the xclbin ./vadd.xclbin
Kernel Name: vadd_1, CU Number: 0, Thread creation status: success
MMAP_FAILED: Invalid argument
terminate called after throwing an instance of 'std::runtime_error'
  what():  Unable to mmap file: /xxx/xxx/xxx/xxx/Vitis-Tutorials/Getting_Started/Vitis/example/u250/sw_emu/.run/102438/sw_emu/device0/memory_map_file(Invalid argument)
Software emulation of compute unit(s) exited unexpectedly
Terminated

I am using Vitis 2023.1 and appropriate platform files.

To Reproduce

• change directory

cd <Path to the cloned repo>/Getting_Started/Vitis/example/u250
mkdir sw_emu
cp xrt.ini sw_emu
cd sw_emu

• compile

g++ -g -std=c++17 -Wall -O0 ../../src/host.cpp -o ./app.exe -I$XILINX_XRT/include/ -L$XILINX_XRT/lib -lxrt_coreutil -pthread
emconfigutil --platform xilinx_u280_gen3x16_xdma_1_202211_1
v++ -c -t sw_emu --platform xilinx_u280_gen3x16_xdma_1_202211_1 --config ../../src/u250.cfg -k vadd -I../../src ../../src/vadd.cpp -o ./vadd.xo 
v++ -l -t sw_emu --platform xilinx_u280_gen3x16_xdma_1_202211_1 --config ../../src/u250.cfg ./vadd.xo -o ./vadd.xclbin

• run application

export XCL_EMULATION_MODE=sw_emu
./app.exe

Do you see this same issue when you use the U250 platform?

[RatkoFri]

I just tested with the U250 platform and I have the same issue.

[RatkoFri]

Solved.

This error arises due to insufficient space on storage. It has nothing to do with Vitis tool.
