Dear OpenBmc, I meet this issues and stuck me for a long times. please support me if u have some clue. 1. update_udev_hwdb error popup for me I just find the kernel configuration files which is .config, then has the problems. Then I just recover the .config files in the tmp directory, but still has the same issues. shilaimao@shilaimao-VirtualBox:~/bmc/romulus-bmc/openbmc/build$ bitbake obmc-phosphor-image Loading cache: 100% |############################################################################| Time: 0:00:04 Loaded 3902 entries from dependency cache.
