The AST2700 I3C controller implements the MIPI I3C HCI specification, which is not yet supported by QEMU. Currently, QEMU only provides an I3C model for the DesignWare controller used on the AST2600. > > 2/ shutdown not working > > [ 246.405297] systemd-shutdown[1]: Entering exitrd... > shutdown: poweroff --timeout=90000000us --log-level info --log-target=kmsg > --log-color --exit-code=0 > /shutdown: line 97: poweroff: not found > Execute poweroff -f if all unmounted ok, or exec /init shutdown-sh# OpenBMC currently only supports reboot. Invoking shutdown causes the system to return to the Linux initramfs instead of powering off. Thanks, Jamin
