  • OpenWrt镜像:archive.openwrt.org/rel
  • OpenWrt工具链:archive.openwrt.org/rel
  • 版本:22.03.2
安装
At the PC:
#unzip the Image
gzip -d openwrt-21.02.0-bcm27xx-bcm2708-rpi-squashfs-factory.img.gz
  • # insert SD-card and check the name, alternatively check dmesg
  • lsblk
  • # copy the Image 1:1 to the SD-card
  • sudo dd if=openwrt-21.02.0-bcm27xx-bcm2708-rpi-squashfs-factory.img of=/dev/mmcblk0 bs=1M conv=fsync
  • 复制代码

    扩展文件系统
    SSH INTO THE RASPBERRY PI:
    opkg install kmod-usb-storage kmod-usb-ohci kmod-usb-uhci e2fsprogs fdisk resize2fs
  • fdisk /dev/mmcblk0
  • (also see the less finicky way by @SemperEnim below):
  • To make it clear what I entered, here the complete session of fdisk. Please note how the first sector remains unaltered:
  • Welcome to fdisk (util-linux 2.36.1).
  • Changes will remain in memory only, until you decide to write them.
  • Be careful before using the write command.
  • Command (m for help): p
  • Disk /dev/mmcblk0: 14.99 GiB, 16096690176 bytes, 31438848 sectors
  • Units: sectors of 1 * 512 = 512 bytes
  • Sector size (logical/physical): 512 bytes / 512 bytes
  • I/O size (minimum/optimal): 512 bytes / 512 bytes
  • Disklabel type: dos
  • Disk identifier: 0x5452574f
  • Device Boot Start End Sectors Size Id Type
  • /dev/mmcblk0p1 * 8192 139263 131072 64M c W95 FAT32 (LBA)
  • /dev/mmcblk0p2 147456 360447 212992 104M 83 Linux
  • Command (m for help): d
  • Partition number (1,2, default 2): 2
  • Partition 2 has been deleted.
  • Command (m for help): n
  • Partition type
  • p primary (1 primary, 0 extended, 3 free)
  • e extended (container for logical partitions)
  • Select (default p): p
  • Partition number (2-4, default 2): 2
  • First sector (2048-31438847, default 2048): 147456
  • Last sector, +/-sectors or +/-size{K,M,G,T,P} (147456-31438847, default 31438847):
  • Created a new partition 2 of type 'Linux' and of size 14.9 GiB.
  • Partition #2 contains a squashfs signature.
  • Do you want to remove the signature? [Y]es/[N]o: n

  • Command (m for help): w
  • The partition table has been altered.
  • Syncing disks.

    REBOOT AND LOG IN AGAIN
    The device usage and sizes are now as follows (my SD-card is 16 GB in size). The size needs still needs to be adjusted:
    df -h
  • Filesystem Size Used Available Use% Mounted on
  • /dev/root 4.3M 4.3M 0 100% /rom
  • tmpfs 217.9M 52.0K 217.9M 0% /tmp
  • /dev/loop0 92.7M 2.6M 83.1M 3% /overlay
  • overlayfs:/overlay 92.7M 2.6M 83.1M 3% /
  • /dev/mmcblk0p1 63.9M 17.3M 46.6M 27% /boot
  • tmpfs 512.0K 0 512.0K 0% /dev
  • 复制代码

    Actually this was easier than expected, simply use resize2fs:
    opkg update && opkg install resize2fs
  • resize2fs /dev/loop0
  • resize2fs 1.45.6 (20-Mar-2020)
  • Filesystem at /dev/loop0 is mounted on /overlay; on-line resizing required
  • old_desc_blocks = 1, new_desc_blocks = 120
  • The filesystem on /dev/loop0 is now 15641408 (1k) blocks long.
  • 复制代码

    AND NOW DF -H RETURNS THE ADJUSTED SIZE:
    df -h
  • Filesystem Size Used Available Use% Mounted on
  • /dev/root 4.3M 4.3M 0 100% /rom
  • tmpfs 217.9M 56.0K 217.9M 0% /tmp
  • /dev/loop0 14.5G 3.1M 13.9G 0% /overlay
  • overlayfs:/overlay 14.5G 3.1M 13.9G 0% /
  • /dev/mmcblk0p1 63.9M 17.3M 46.6M 27% /boot
  • tmpfs 512.0K 0 512.0K 0% /dev
  • 复制代码
