Subject: [U-Boot] generating a script file in FIT_SIGNATURE context
Hi all,
In my setup, I have activated FIT (without signature in a first step), and I
boot using standard script way (boot.scr), which I generate with the following
command :
mkimage -A arm -T script -C none -n "My boot script" -d boot.txt boot.scr
It works fine, and I can "load" and "bootm" the FIT image.
Now I would like to activate fit_signature. When I write manually all the
boot.txt script commands in the console, it works fine. So it means that the
FIT image is well generated, and the u-boot is well-configured. That's a good
point.
But I have some problems to run the generated boot.scr in that case. I think
the script should also be generated with the signature. Do you confirm that?
If this is the case, from your point of view, which fields should I add to my
previous command? -F ? -k ? -K? others?
Thanks in advance for your feedback
Best Regards
Nicolas
Hi again,
I think I found the clue.
When CONFIG_FIT_SIGNATURE is not enabled, then CONFIG_IMAGE_FORMAT_LEGACY is
automatically enabled, this allow to treat correctly the boot.scr.
If CONFIG_FIT_SIGNATURE is enabled, we have to set CONFIG_IMAGE_FORMAT_LEGACY
to be able to keep that.
With this, it seems ok on my side.
Best Regards
Nicolas
