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-globalscale_mirabox-initramfs-kernel.bin 52cb7af50ae204c61d27f9b12e3a4af14888406dddbb7ab08304a4e15f4c6b3c openwrt-25.12.5-mvebu-cortexa9-globalscale_mirabox-initramfs-kernel.bin
