The .axf file is something traditionally called ARM eXecutable Format, which these days it's just an ELF format that the model can load directly. The above code contains the pre-Linux boot initialisation, the kernel Image (uncompressed, doesn't have a decompressor) and possibly a filesystem, unless you use the --block-device model option. To get the boot wrapper, just clone this: git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/boot-wrapper-aarch64.git The README and Makefile should be enough to get you started. > Also, what is libarmctmodel.so? I think that's the library that contains the actual software model. -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
