@telphan have you made any additional progress on minimizing boot time. I have tested this to be in userspace, but can not find a way how to test this outside...

@agherzan Sure, here we go, testing with `resin-XXXX-2.2.0+rev1-dev-v6.1.2.img` Our application is available on the following link: https://github.com/IRNAS/PiRA-zero-firmware as it is a battery powered system waking up for example very hour...

@agherzan I have poked around the host OS to find some logs that would show more info, but no luck.

Using command `journalctl -x -a > log.log` I have received the hostOS log attached. [log.log](https://github.com/resin-os/resinos/files/1506813/log.log)

I wonder if there has been any work done with ResinOS in the boot time optimization recently.

Using the default GNSS example should give you a good starting point and that works well with this library.

I have implemented the first version of the code to do this: https://github.com/SloMusti/ArduinoCore-stm32l0/commit/c134cc5d1a250b91b31d651c09138f2133a0e4bc Currently it does not appear to work yet, given that aopcfg status is always shown as 0...

Added also the message enable for aopstatus, however event this appears to be insufficient: https://github.com/SloMusti/ArduinoCore-stm32l0/commit/efe596965ac24374ee5b9dc024c6a0bbed993639

Now verified that the GPS module is sending AOPSTATUS message. ``` 08:39:20 R -> UBX NAV-PVT, Size 100, 'Navigation PVT Solution' 08:39:20 R -> UBX NAV-SAT, Size 256, 'Satellite Status...

@GrumpyOldPizza this message is only enabled if `Autonomous mode is enabled`, please see https://github.com/SloMusti/ArduinoCore-stm32l0/commit/efe596965ac24374ee5b9dc024c6a0bbed993639 Given I have verified that GPS is actually sending this and the code still does not...
