WP76xx - swiapp crashing

Hello,

Is there any documentation or source code on swiapp?

We have encountered an issue where swiapp crashes several days after having run fwupdate downloadOnly file_name, and would like to understand the reason and impact for it.

Here is how it is observed in the logs:

73302:Sep 20 18:16:01 hhv2 user.notice root: restart_swi_apps: swiapp killed, restart it
73322:Sep 20 18:16:04 hhv2 user.notice root: restart_swi_apps: killing hostapd by signal KILL
73323:Sep 20 18:16:04 hhv2 user.notice root: restart_swi_apps: aplay does not exist
73324:Sep 20 18:16:04 hhv2 user.notice root: restart_swi_apps: arec does not exist

An immediate impact was that restart_swi_apps would kick in and kill hostapd (which we use), but fortunately this service could be modified in the distribution to prevent killing hostapd.

Any insight on swiapp role and behaviour would be very helpful.

Thanks,
Best regards
