Howdy,
I'm working to integrate SWUpdate and Hawkbit on a buildroot based embedded linux device. I'm currently able to install images from Hawkbit, however, I'm having trouble getting the device to report that it has finished/tested the update to Hawkbit. After downloading and installing the image, I get the following message from SWUpdate whenever it polls the Hawkbit server, even after restarting SWUpdate, as they suggest.
[TRACE] : SWUPDATE running : [get_state] : Read state=1 from persistent storage.
[WARN ] : SWUPDATE running : [server_has_pending_action] : An already installed update is pending testing, ignoring available update action.
[INFO ] : SWUPDATE running : [server_has_pending_action] : Please restart SWUpdate to report the test results upstream.
[DEBUG] : SWUPDATE running : [start_suricatta] : No pending action to process.
So, I have a few questions:
1) What is the name of the bootloader environment state variable that stores the update status? Looking at config.in, seems like it's configurable via menuconfig, and defaults to ustate?
2) Running fw_printenv, it doesn't look like I have any variable named ustate in uboot's environment (and I know that I haven't configured one). If the update status is stored in "ustate" , but that variable hasn't been set up in uboot, how is SWUPdate able to "[get_state] : Read state=1 from persistent storage."?
3) Is it the responsibility of the end user to run tests and update the update status environment variable back to "OK"? I.e. restarting swupdate alone won't do anything unless I change the update status environment variable. I think the answer is yes, but I need to know how to access the variable to do this :)
Thanks!

This was already discussed, see :

You have to inform SWUpdate if the new software runs flawlessly. In most
cases, system reboots after an update and the new software should start
SWUPdate with the "-c <state>" parameter. This is forwarded to Hawkbit.

If you set U-Boot as bootloader, the variable is handled by SWUpdate.
Its value should become "1" (installed).

OK ?

Variable is set / reset by SWUpdate if you start it after an update with
-u "-c <state>".

Ah, how could I miss that? Thanks Stefano. To be clear though, if I wanted to modify ustate in a UBoot script as well instead of starting with the -c option, I can create a UBoot environment variable named ustate and modify it in bootloader scripts and that should also work?

You just can reset the variable, but it won't work.

If you do not start with "-c", SWUpdate does not know which is the
status afetr installing - if new software could not be started, after a

Hi Stefano,
Pardon me for being a little confused, but using a uboot environment variable named 'ustate' instead of the -c flag does in fact seem to work for notifying a hawkbit of a successful update. The status assigned with the suricatta -c flag just seems to override the uboot persistent state set by the ustate variable.
Are the update_state_t enumerated in state.h supposed to be the same as the statuses given for the -c flag? E.g 1=AGAIN, 2=SUCCESS, 3=FAILED? They seem to be, except that 2=SUCCESS doesn't seem to match STATE_TESTING.
Thanks again for your help! Your project has been super helpful in getting our software update system off the ground.

Yes, the parameter can override the value of the ustate variable. It is

ok how you set it.

It could be a little confusing. Anyway, 1=INSTALLED is set automatically

after a successful update, and putting the state into 2=TESTING (aks
SUCCESS) means that the new software was started and a feedback is sent
to Hawkbit.

Dear Stefano,
I'm writing on this old post because I have the same doubt: I'm not clear on why the value 2 should be used after an update to report that the update was successful.
In the documentation at https://sbabic.github.io/swupdate/swupdate-best-practise.html#update-concept, I also see that the ustate variable should be set to 0.
Am I misunderstanding something, or does the documentation need to be updated?
Best regards,
Stefano.

Documentation is correct, ustate is reset to 0 when the transaction is
completed.
SWUpdatwe handles autoimatic the transition 0 (NORMAL) to 1 (INSTALLED).
When the system is booting, you have still the possibility to introduce
another state (if required), or you complete the transaction (as I
usually do, and ustate is set to 0). As Framework, you have free hands.
You decide yourself when the update is successfully tested. Note that
the flag passed to SWUpdate via -c is not the ustate. It declares the
final status of the transaction to be passed to the server. So yes,
SWUpdate will be started with "-c 2" (it means success), and at the same
time the ustate env variable is reset to 0.

to swupdate
Thank you Stefano for the clarification (and the quick reply).
I understand the flexibility given by the tool.
So it is wrong to set ustate to 2 in env after a reboot and a successful update before the swupdate startup?
Looking into the code if I set ustate to 2 then swupdate will set it to 0 after sending the "transaction close" message to the server.
Best regards,
Best regards,
Stefano.

The bootloader touces ustate only in case of a fallback, that is new

software does not start. In that case, it should marked the update as
failed by setting ustate=3.
Else ustate is not touched at all.
