mkimage: Can't set header for FIT Image support: Success

Bug Description

When creating a devicetree image with the command:

   mkimage -O linux -A powerpc -C none -T flat_dt -d input.dtb output.ub

This results in an output.ub with an all-zero uboot header, the error message:

  mkimage: Can't set header for FIT Image support: Success

And it exits non-zero.

I'm not trying to build a FIT image (-f); I'm just wanting my pre-compiled fdt prefixed with a header containing ih_type==8.

I looked at the source and I think that tools/fit_image.c's fit_check_image_types() is tooaggressive. FIT should only be selected if a -f option is specified (and not if -T flat_dt is specified).

Thanks for the report; Debian/Ubuntu don't patch the mkimage code at the moment, so maybe you could work directly with upstream to solve this? It seems you started diving into this, do you already have a tentative patch to address the issue?

Thanks!

No patch; to fix, some significant interface surgery looks necessary. My current workaround is a small custom mkimage that uses crc32 from libz. I will look into pushing this bug upstream.
