Re: [U-Boot] [PATCH] Revert "fdt: Fix FIT header verification in mkimage and conduct same checks as bootm"

(Forgot to reply all. Sorry for the clutter Vagrant)

See the patch I just submitted "fdt: Fix mkimage list to try every header type" for what I believe to be the correct fix for this problem.

Thanks, Jordan

This reverts commit d32aa3cae44e618048ff7f378577d44f9b6d6dcc.

This breaks the "list_image" test in tests/image/test-imagetools.sh, where mkimage and dumpimage are expected to have the same output:

Listing image contents... # debian/build/tools/tools/mkimage -l linux.itb debian/build/tools/tools/mkimage: verify_header failed for Default Image support with exit code -9

Obviously, blindly reverting this patch may not the best way forward,

I'll take a look at this today and see if there's a simple way forward without reverting

...

but the same verify_header failed message occurs also with some real-world .itb files, such as that used on the pinebook. So it's not

Would you be able to point me to any .its files that fail this check in the real world.

Also are you seeing failures while creating the image from its as well with real world images (mkimage -l its itb) or only when listing the header with -l?

...

just the tests that need to be updated.

live well, vagrant
