I m following the tutorial Vitis_Platform_Creation/Design_Tutorials/01-Edge-KV260/step3.md and i finally TEST PASSED. But I have met 2 problems: When I try ed to run host code without using xmbutil before, linux os will collapse. Then I tried to run xmbutil unloadapp
and xmbutil loadapp <any app>, xmbutil will stuck in python at a function call which named "waitpid".
