Boot Information

<<< Welcome to NixOS sd-card-25.05.20250328.2cc0d7f (riscv64) - ttyS0 >>>
The "nixos" and "root" accounts have empty passwords.

To log in over ssh you must set a password for either "nixos" or "root"
with `passwd` (prefix with `sudo` for "root"), or add your public key to
/home/nixos/.ssh/authorized_keys or /root/.ssh/authorized_keys.

If you need a wireless connection, type
`sudo systemctl start wpa_supplicant` and configure a
network using `wpa_cli`. See the NixOS manual for details.


Run 'nixos-help' for the NixOS manual.
