config internal 'ccache'
        option enable '0'

重启即可

扩容root分区

安装依赖

1
opkg update && opkg install block-mount kmod-fs-ext4 kmod-usb-storage kmod-usb-ohci kmod-usb-uhci e2fsprogs fdisk

查看sd卡信息

1
block info

有类似回显，其中/dev/mmcblk0p1就是sd卡

1

3
/dev/mtdblock5: UUID="d1f1302b-91ce24ca-2c74336e-eea51b51" VERSION="4.0" MOUNT="/rom" TYPE="squashfs"
/dev/mtdblock6: MOUNT="/overlay" TYPE="jffs2"
/dev/mmcblk0p1: UUID="746ffc51-1f29-2646-b2cb-fc2c03fe3c1a" LABEL="sdcard" VERSION="1.0" TYPE="ext4"

格式化内存卡

1
mkfs.ext4 /dev/mmcblk0p1

将下面的DEVICE换成你的sd卡分区

DEVICE="/dev/mmcblk0p1"
eval $(block info "${DEVICE}" | grep -o -e "UUID=\S*")
uci -q delete fstab.overlay
uci set fstab.overlay="mount"
uci set fstab.overlay.uuid="${UUID}"
uci set fstab.overlay.target="/overlay"
uci commit fstab

转移数据

如有报错请先查看否自动挂载了sd卡，挂载sd卡时也可能出现如下报错，实测不影响。

root@GL-MT1300:~# mount /dev/mmcblk0p1 /mnt/
NTFS signature is missing.
Failed to mount '/dev/mmcblk0p1': Invalid argument
The device '/dev/mmcblk0p1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

执行以下命令：

mount /dev/mmcblk0p1 /mnt
cp -f -a /overlay/. /mnt
umount /mnt

然后重启
