Hello,

I'm looking for how to virtualize a openwrt ramips image, so i know that in the download page of every release there is a vmlinux .elf  file, or i can use also le or be malta images. But i need to do some changes and i can't modify the elf image to run with qemu-system-ramips  (mipsel or whatever). This, because im testing some hardware that i haven't physically access, and i need to test it.

So, is there a way to make a elf, img or some VM image with my changes to test what i need? or It's possible to modify a elf image every time that i need to change something to test in qemu?

Regards

You can have a writeable ext4 partition as rootfs when using malta/mips in qemu.

You can modify the kernel/rootfs in the buildroot by patching the sources or by using the files/ dir (files in that dir get 1:1 into rootfs).

You can check the commands / Makefile in the build system how the elf/... other files are created (see target/linux/<arch>/... )
