This gives us a bit of a look into the signature that mkimage added. Note you
can also use fdtdump to list the entire device tree.
Say we want to change the kernel that this configuration uses
-(/images/kernel@1). We could just put a new kernel in the image, but we will
+(/images/kernel). We could just put a new kernel in the image, but we will
need to change the hash to match. Let's simulate that by changing a byte of
the hash:
- fdtget -tx image.fit /images/kernel@1/hash@1 value
+ fdtget -tx image.fit /images/kernel/hash-1 value
c9436464 6427e10f 423837e5 59898ef0 2c97b988
- fdtput -tx image.fit /images/kernel@1/hash@1 value c9436464 6427e10f 423837e5 59898ef0 2c97b981
+ fdtput -tx image.fit /images/kernel/hash-1 value c9436464 6427e10f 423837e5 59898ef0 2c97b981
Now check it again:
configuration in any way. Try it with a fresh (valid) image if you like by
running the mkimage link again. Then:
- fdtput -p image.fit /configurations/conf@1/signature@2 value fred
+ fdtput -p image.fit /configurations/conf-1/signature-1 value fred
$UOUT/tools/fit_check_sign -f image.fit -k am335x-boneblack-pubkey.dtb

The following properties are required in the FIT's signature node(s) to
allow the signer to operate. These should be added to the .its file.
Signature nodes sit at the same level as hash nodes and are called
-signature@1, signature@2, etc.
+signature-1, signature-2, etc.
- algo: Algorithm name (e.g. "sha1,rsa2048")
- hashed-nodes: A list of nodes which were hashed by the signer. Each is
a string - the full path to node. A typical value might be:
- hashed-nodes = "/", "/configurations/conf@1", "/images/kernel@1",
- "/images/kernel@1/hash@1", "/images/fdt@1",
- "/images/fdt@1/hash@1";
+ hashed-nodes = "/", "/configurations/conf-1", "/images/kernel",
+ "/images/kernel/hash-1", "/images/fdt-1",
+ "/images/fdt-1/hash-1";
- hashed-strings: The start and size of the string region of the FIT that
was hashed

You can see that we have added hashes for all images (since they are no
longer signed), and a signature to each configuration. In the above example,
-mkimage will sign configurations/conf@1, the kernel and fdt that are
-pointed to by the configuration (/images/kernel@1, /images/kernel@1/hash@1,
-/images/fdt@1, /images/fdt@1/hash@1) and the root structure of the image
+mkimage will sign configurations/conf-1, the kernel and fdt that are
+pointed to by the configuration (/images/kernel-1, /images/kernel-1/hash-1,
+/images/fdt-1, /images/fdt-1/hash-1) and the root structure of the image
(so that it isn't possible to add or remove root nodes). The signature is
-written into /configurations/conf@1/signature@1/value. It can easily be
+written into /configurations/conf-1/signature-1/value. It can easily be
verified later even if the FIT has been signed with other keys in the
meantime.
