Should the FIT signature checking really be part of the 'fdt' command ?
Shouldn't 'bootm' check the signature (well, 'bootm prep' or such does)
or somesuch command ?
Why not? I use this "fdt check" command for example in a script, for
checking if the FIT image is correct signed, and if so, update with
the binaries in it some UBI Volumes (not only kernel, dt and/or
rootfs) ... but if this is not accepted, I can look into the bootm
command if I can use it ... but I do not want boot the FIT image ...
But doesn't 'bootm prep' (aka. prepare the image for booting, but do not
actually boot) do the same thing ? It does verify the image etc., right ?
Yes, but maybe do "etc" things I do not need?
From the "bootm prep" help text:
"prep - OS specific prep before relocation or go"
"OS specific prep or go" ... Hmm...
- The "fdt checksign" command (as I renamed it in v2) does no "OS
specific" things, only check the signature of the FIT image.
There is no OS dependency ... With "bootm prep" there are maybe
done OS specific things with the FIT Image ...
maybe in my case it would work, but is this true for all boards?
- "or go" ... I definitely do not want to boot the FIT Image!
CC Simon, he might clear this up. I'm sick (flu?) and I don't want to leave this
Simon is on Cc, and he remarked to rename this "fdt sign" into "fdt
checksign", I did in the "v2" of this patch ...
thread hanging , sorry.
Bad news. I hope you get well soon!
bye,
Heiko
