Hi Quentin, > So I guess it's "fine" (although you won't be able to do a proper secure > boot with this enabled). So you can keep it in.
I discovered that OpenWRT is still using the legacy U-Boot image file format script [1], too. And the `source` command for executing this type script also requires `CONFIG_LEGACY_IMAGE_FORMAT=y` [2]. Therefore, CONFIG_LEGACY_IMAGE_FORMAT=y is still required in many open-source projects. (Actually, Armbian also used the legacy U-Boot image file format script) [1] https://github.com/openwrt/openwrt/blob/7edb29d241dbd4acd0a716a3735dedd5ac3b36e2/target/linux/rockchip/image/Makefile#L24 [2] https://github.com/u-boot/u-boot/blob/master/doc/usage/cmd/source.rst Cheers, Liangbin
