Hi everyone,
I have read in the OTA documentation that “By using the OTA Agent library, you can logically separate firmware updates and the application running on your devices.” [1]
Q1) Is firmware synonym to OS in this context?
Q2) Does that mean that I can partially update a device, by adding/removing/updating an application?
(I suppose changing the firmware only is more problematic, since the application contains references to it.)
In the same page, there is also a “Example Usage” of a firmware update, which ends with a reboot.
Q3) I suppose a reboot is always required after a firmware update, correct?
(due to dependencies/references, system state, etc.)
2) Is a reboot also required when applications are added/removed/updated?
3) Is it fundamentally possible to perform any OTA update without rebooting the device?

Thanks in advance!
