https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274092 --- Comment #17 from Patrick M. Hausen <pmh@hausen.com> --- Unfortunately I cannot boot the board without USB Ethernet connected. It's a compute module placed into this board: https://www.waveshare.com/wiki/Compute_Module_PoE_Board Also although I tried for a long time I could not get serial console to work. So once the system crashes at boot and I lose SSH access all I can do is re-image. With a debug kernel will there be more output to get a screenshot with a camera? Or can I dd the entire EMMC of the module to a file and then extract information, somehow? Kind regards, Patrick For the moment I am satisfied to be able to use these tasks in Ansible to solve the matter: - name: Read serial number ansible.builtin.shell: | set -o pipefail && /bin/kenv | \ /usr/bin/awk '/smbios.system.serial/ {printf "%s:%s:%s\n", substr($0, length($0)-6, 2), substr($0, length($0)-4, 2), substr($0, length($0)-2, 2)}' register: mac_lower changed_when: false - name: Set MAC address ansible.builtin.copy: dest: "/etc/start_if.{{ network.wired.interface }}" owner: root group: wheel mode: '0644' content: | /sbin/ifconfig $1 down /sbin/ifconfig $1 link b8:27:eb:{{ mac_lower.stdout }} /sbin/ifconfig $1 up Anyway what would be the result if we get this to work? As I have been arguing on the mailinglist the RPi foundation clearly documents that we should use the device's serial number to generate the MAC and nothing else for all RPi 3 and older.
