Installation notes

  • Already running OpenWrt or ImmortalWrt: flash the sysupgrade image from LuCI (System → Backup / Flash Firmware) or with the sysupgrade command.
  • The kernel / initramfs image boots from RAM without writing to flash — useful for a first install or for recovering from a failed flash.
  • Verify your download against the published checksum before flashing:
    $ sha256sum openwrt-25.12.5-mvebu-cortexa9-iij_sa-w2-initramfs-kernel.bin
    d7f16b50ab9446a93ebc90b7958c64dbac0e95c0642fb139f115ae24029433bc  openwrt-25.12.5-mvebu-cortexa9-iij_sa-w2-initramfs-kernel.bin
