One thing is to add your reply at the bottom, not the top.

Actually it is 'dumpimage -l file.fit' to list the contents of your
fit file called 'file.fit'.  The program is built in the tools/
directory or your build, or you can

I mean if you are completely stumped, go to where the error is
generated and add lots of debugging around it. This is
boot_get_kernel() which is in v2021.10 is in common/bootm.c - so just
add lots of printf() stuff there, rebuild and run on the board and see
if you can figure out what is wrong. From my side I am really not
sure.

Feel free to share the FIT through a link if you like.

Also, you could try using a simple FIT without the signature part.

[..]

This has CONFIG_FIT and CONFIG_LEGACY_IMAGE_FORMAT is disabled (since
you have signature verification on).
