to swupdate

Hello,

I am developing an update that also uses the sw-versions. What I am looking for is an implementation that if the version of the update has already been installed on the board, then the board should not be restarted after the update. If, on the other hand, the version of the update that I want to install has not been installed on the board then after update I want to restart the card.

Do you know a way to implement such a situation with Swupdate?

Regards,

N

Hi Orlando,

if you look at the documentation you will see that swupdate is able to check the software version before installation.

As it can be seen below, swupdate can check the version of a sub-image or the version of the whole swu-image.

SWUpdate: software update for embedded system — Embedded Software Update Documentation 2022.05 documentation (sbabic.github.io)

SWUpdate: syntax and tags with the default parser — Embedded Software Update Documentation 2022.05 documentation (sbabic.github.io)

Swupdate will reject the installation and not execute the postinstall command "reboot" if you use the version tag from sw-description

to compare the version of the update image and the version of the installed image. (whole swu-image)

# sw-description-template

software = {
version = "1.2.3";

........................

images: ({

................

install-if-different = true;
................
};

# run swupdate with -R command

# you can also use the swupdate.cfg file to pass the argument (no-reinstalling) to swupdate.

$ swupdate -R 1.2.3 -i demo.swu ..... -p reboot

.......................................................

[ERROR] : SWUPDATE failed [0] ERROR core/parser.c : parse : 243 : No reinstalling allowed: new version 1.2.3 == installed 1.2.3
[ERROR] : SWUPDATE failed [0] ERROR core/stream_interface.c : extract_files : 165 : Compatible SW not found

Hi,

I have to correct one thing.

installed-if-different tag is not needed here if you want to check the version of entire swu image.

installed-if-different tag is used to check the version of a sub-image. At this point you should also define name and version tags under each sub-image,

if you want to check their installed versions.

Best regards
