Hi,
I want to flash a µCtrl, as part of a "Install group" using RAUC and (if
necessary) a custom Handler (?).
Looking at
https://github.com/rauc/rauc/blob/master/test/install-content/custom_handler.sh
I was wondering about the progress indication.
What's the supposed way to extend RAUC to handle some kind of binary bundled
within the raucb and communicate the update progress back to the (already
implemented) Update Controller?
the `custom handler` you took a look at is something different than what
you require. It is a way to fully customize the entire RAUC installation
process using a script or a binary.
I guess this is not what you intend to do.
If I got it right, you only want to have a custom handling for a single
slot class.
This is what RAUCs `hooks` [1] are for. Or, to be more detailed, what
the per-slot `install` hook [2] is for.
Hooks are defined in your Bundles manifest and provided by a single
`hook` script that must be placed inside the bundle and referred to in
the bundle section `[hooks]`:
[hooks]
filename=my-hooks.sh
Then you have to add to your µCtrl-Slots image section the line
[image.uctrl]
...
hooks=install
This will make RAUC calling the hook skript instead of performing the
default installation routine for this slot.
In the hook script you should check for being executed with the
arguments matching your slot. An example for this is in the
documentation. Slightly adapted to your needs it will look something
like this:
#!/bin/sh
case "$1" in
slot-install)
# only uctrl needs to be handled
test "$RAUC_SLOT_CLASS" = "uctrl" || exit 0
uctrl-update-routine "$RAUC_IMAGE_NAME"
;;
*)
exit 1
;;
esac
exit 0
Does that help you?
Best regards
Enrico
