In order for this to work, you will need to also set the compat_version _on device_ either with board.d or uci-default. In case of fresh install typically the uci-defaults method provides a better experience. Examples: board.d: https://github.com/openwrt/openwrt/blob/master/target/linux/kirkwood/base-files/etc/board.d/05_compat-version uci-defaults (at the bottom): https://github.com/openwrt/openwrt/commit/07aa858a73e6e855fc62a37ae275518fa4db5e50 Best Adrian > + DEVICE_COMPAT_MESSAGE := Kernel partition has been resized to 6M. \ > + A sysupgrade will brick your device. \ > + Please install a fresh factory image via bootloader. \ > + Alternatively, you can flash sysupgrade-6M-Kernel.bin with \ > + zcat sysupgrade-6M-Kernel.bin | mtd -r -e /dev/mtd3 write - > /dev/mtd3 .\ > + This may thow an error, because it is a 256M image.
