Remove system dependency from charger driver implementation. Remove circular, lambda driven dependency between charger and brownout detector. Remove event manager dependency in driver as well. Encapsulate some of charger logic in introduced battery controller. Extract path configuration to the separate target to decouple charger from vfs middleware.

vfs for PurePhone
What does this module provide?
We use POSIX calls wrapper to have proper filesystem experience.
File systems in use
Right now we are able to use 2 file systems
- FAT-FS
- LittleFS
PurePhone partitions
PurePhone has 3 flash partitions:
- for update and backup
- FAT for phone data
- LittleFS for user data
LittleFS partition is needed to assert minimal to possibly no data loss in unexpected shutdown
how to use PurePhone partitions
Pure phone on reboot on option 4 will present itself with 3 partitions via USB, the first two should be auto mount.
mounting FAT-FS partitions
- check which devices are PurePhone block devices ie with:
dmesgorlsblk - mount them with i.e
udisksctl mount -b /dev/sdbXwhere X is number of block device
mounting LittleFS partitions
For LittleFS you will have to use fuse to mount partition. Tool is already build with release and is ready to use:
- Prepare mount point i.e. create catalog
mkdir mymount - Mount:
./lfsfuse --block_size=32768 /dev/sdb3 mymountwhere sdb3 is device where you expect Pure LittleFS partition - Enter here and play with user data
- Umount and eject the device i.e. with:
udisksctl power-off -b /dev/sdb - Phone will reboot with changed data
