I just found out I have the same issue reported here: While update BlueField-3 dpu with bf-bundle-3.0.0-135_25.04_ubuntu-22.04_prod.bfb the os can not be run
The only difference is that my secureboot is disabled already. Yet facing the same issue. I have yet to try the suggestion to get 24.04 bfb bundle.
Where can I get 24.04 bfb bundle? I can only find Ubuntu 22.04 here NVIDIA DOCA Downloads | NVIDIA Developer
