Boot form SD and in emergency mode

Nobody has claimed this yet.

when i boot from SD with debian written in , it will enter emergency mode. what i used is genesys2_ariane_xilinx.new.mcs and rootfs.tar.xz download from https://github.com/lowRISC/lowrisc-chip/releases

the message is as flowed:

You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or "exit"
to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):
root@lowrisc:~# ls
root@lowrisc:~# cd [ 395.732706] random: crng init done

Start with the genesys2_ariane_xilinx.new.mcs image and rootfs.tar.xz, then inspect journalctl -xb from emergency mode. Compare the boot configuration with the missing /dev/hvc0 and /dev/rda1 through /dev/rda4 devices; done means Debian boots normally without emergency mode and the expected mounts, swap, and serial getty start.
