Vitis GUI projects on RHEL83 and CEntOS82 may fail because of a lib conflict in the LD_LIBRARY_PATH setting. User needs to remove ${env_var:LD_LIBRARY_PATH} from the project environment settings for the function to build successfully.
SVM L2 PL function fails hardware emulation with 2022.1 Vitis. Please use 2021.1 Vitis for this function.
rgbir2bayer, isppipeline_rgbir PL functions are not supplied with input images
Software emulation for Warptransform L2 testcases doesn’t work because of a known issue with platform.
Warptransform L1 URAM cases fail CSim because of a known HLS issue.
Hardware emulation in AIE testcases may throw segmentation fault at the end, although completing the functional test successfully.
