SDCard にファームウェアと同じ root filesystem を使用して、LTE 接続などを利用できる環境で起動します。
※ 下記のような用途には向いていません。
MA-X3xx の実機や PC など、ext4 ファイルシステムを扱うことができる機器に SD Card を挿入します。
[ 710.631902] mmc1: new ultra high speed SDR104 SDHC card at address 59b4 [ 710.632946] mmcblk1: mmc1:59b4 ABLG0 14.5 GiB [ 710.635670] mmcblk1: p1
購入したばかりの SD Card など、パーティション構成が用途に合わない場合はパーティションの作成を行います。
2 番目のパーティションを root filesystem として使用するようになっているので、
としてパーティションを作成します。

2番目のパーティションに、ext4 のファイルシステムを作成します。

適当なディレクトリに SD Card のファイルシステムを mount します。
root@metis:~# mount /dev/mmcblk1p2 /mnt/sd root@metis:~#
USB Memory や SFTP などで持ってきて、mount した場所で展開します。
root@metis:~# cd /mnt/sd/ root@metis:/mnt/sd# tar axf /tmp/MAX3xx_rootfs_jammy_v6_1_1.tar.xz root@metis:/mnt/sd#

起動している Kernel の Kernel module を SD Card にコピーします。
root@metis:/mnt/sd# cd lib/modules root@metis:/mnt/sd/lib/modules# cp -af /lib/modules/6.1.46 . root@metis:/mnt/sd/lib/modules# ls -l total 4 drwxr-xr-x 3 root root 4096 Dec 2 08:00 6.1.46 root@metis:/mnt/sd/lib/modules#
unmount しておきます。
root@metis:/mnt/sd/lib/modules# cd root@metis:~# umount /mnt/sd root@metis:~#
SD Card を root filesystem として起動するため、DIPSW-2 のみ ON(下側) に設定し、再起動します。
root@metis:~# reboot Session terminated, killing shell... ...killed. Terminated user1@metis:~$
bootloader の出力から、SD Card を root filesystem として起動していることを確認できます。
