2 years ago Hello, you are building XRT that is 3 years old (as you said xrt_2019.2). It is hard to get support for those old XRT release because things moves fast in last 3 years. It is possible that old XRT release cannot work the card you are using. Which card you are using and which platform?
You dont need to run your hello world example. When xbutil query or xbutil status is showing no device found, then you cannot do anything further. There is no need to run application (hello world or otherwise).
With that old release and without knowing which card/platform you are using I think it is difficult to get support of this issue. You can try in Xilinx Forum though. You can also troubleshoot from the Alveo Debug Guide: https://xilinx.github.io/Alveo-Cards/master/debugging/build/html/docs/card-not-recognized.html

i build and install xrt_2019.2 on ubuntu 18.04, (1) lspci -vvv -d 10ee:
xclmgmt and xocl kernel driver can be recognized
(2) sudo /opt/xilinx/xrt/bin/xbmgmt flash --scan
Flashable partition running on FPGA and Flashable partition running on FPGA can be recognized
(3) run Vitis_Accel_Examples_2019/hello_word example sw_emu/hw_emu is ok (make all and make check are ok) make all hw is also ok,but make check hw is error, error information as follows, XRT build version: 2.3.1301 Build hash: 192e706aea53163a04c574f9b3fe9ed76b6ca471 Build date: 2022-06-15 11:16:00 Git branch: HEAD PID: 159059 UID: 1000 [Mon Jun 20 09:59:27 2022] HOST: ubuntu-wf EXE: /home/ubuntu/git_file/vitis_examples_2019_2/Vitis_Accel_Examples/hello_world/host [XRT] WARNING: No devices found [XRT] ERROR: No devices found [XRT] ERROR: No devices found [XRT] ERROR: No devices found ..//common/includes/xcl2/xcl2.cpp:46 Error calling err = cl::Platform::get(&platforms), error code is: -1001 Makefile:143: recipe for target 'test' failed make: *** [test] Error 1 (4) sudo /opt/xilinx/xrt/bin/xbutil status INFO: Found total 1 card(s), 0 are usable ERROR: Card index 0 is out of range

The following link seems to have a solution, but the solution page is missing.... https://support.xilinx.com/s/question/0D52E00006hpKXASA2/first-alveo-u280-kernel-run-xrt-error-no-devices-found?language=en_US&t=1655704503345
How should I deal with this cl::Platform::get(&platforms), error code is: -1001 and ERROR: No devices found ? thanks
