* Added mechanism enabling CPU to
enter WFI mode when the OS is
in idle, what results in large
power consumption reduction.
* Added mechanism to switch SDRAM to
self-refresh mode before entering
WFI, what resulted in further power
consumption reduction.
To allow the automation of gathering logs and swapping out OS images during tests a MSC reboot
endpoint was added. Together with a change to ecoboot, this allows the sending of a "reboot to
MSC" command. The deivce will then reboot and enter MSC mode.
* Adding document describing how to use logger
* Adjusting logs to follow a new guide
* Change order in log header:
line number is now before function name
- Sentinel locks the frequency when pressing buttons and the encoder.
- The "user activity" sentinel will be properly managed by the system
(CpuGovernor) just like other sentinels.
- Adding information about active sentinels in the power management
statistics logs
Multiple fixes of clock switching related
stability issues:
* added RC oscillator hysteresis as in NXP example;
* changed DCDC converter config;
* configure PLL2 to be able to run on any CPU
frequency level;
* added switching to 1.275V (overdrive) voltage
when applying any clock change above 12MHz as
well as LDO or bandgap switching, as done in
Mbed OS' lpm.c for RT1050;
* changed BMCR AXI queues weighs for SDRAM
in JLink scripts to disable operations
reordering, as it is known to cause data
integrity issues;
* extracted some code to separate files;
* smaller or bigger code cleanups.
Changed startup services order.
Prevent handling multiple "close ready" messages from one service while closing
system.
Introduced a new state in ServiceGUI.
Fixed a problem with turning on Harmony with a connected USB cable.
Add new bell welcome window
Add new close reasons
Add new actions
Bump assets version
Remove bold text from welcome message
Remove bold text from onboarding popups
Remove mechanics enabling to perform reboot
to MSC mode by sending request to one of the
endpoints via serial port, as it is not
implemented in bootloader and may potentially
be unsafe.
Fix of the issue that factory reset screen
informing user of need to manually turn
on the phone to continue the process
was appearing also when restarting to
backup or restore.
Redesign of backup and restore endpoints in the
service-desktop to delegate responsibility for
execution of the actual backup and restore process
onto the Updater.
Due to losing bytes the logger has a worker
which is responsible for dumping logs to
the file. The logger also has its own timer
to dump logs every 15 minutes. EventManager
is not responsible for interval dumping logs
now.
While restoring system data the timer can turn off power of E-ink
to save the power. To avoid this situation we need to power on
the E-ink before wiping out the display. The restore procedure
also performs reversing services list to close. In this case
we do it twice so the order is wrong.
* Dependencies between service-gui and service-eink
have been correctly defined.
* System close routine was replaced with the sequential one
which should solve many bell issues.
* It also fixes BH-1406 and BH-1442.
* Fixed some weird CMake issues in module-audio and
several other modules.
* Fixed service-gui closing routine
* Removed unneeded messages/states from service-gui/eink.
* Enhanced app-mgr closing routine. Fixed closing action handling.
After disconnecting the USB cable, the CPU consumption
increased to over 80% (for 4 MHz), which resulted
in a cyclical change in the CPU frequency and finally
a much shorter battery life.
Made sure all system is deinitialized during update.
Currently there are two exceptions: service eink and service
desktop. There are some issues with them but it should be fixed
in the near future
Gets data from freertos and prints on frequency change depending
if it's important. Gathering is not costly, printing is though.
For less intrusive checks I would rather disable names gathering
as in worst case scenario it hangs rtos context switching till
thread id is found.
Added atexit functionality. All global destructors and functions
registered with atexit() should be called at program exit.
It was possbile to reuse original newlib implementation with
MALLOC_PROVIDED flag set.
Made sure logger destructructor is called as last one.
Due to mudita OS legacy, it was not possible to simply fix dependencies
in global objectes and hence there are neither global objects
destructors nor functions registered with atexit() called when exit()
is called.
Possibly it will be changed later.
Add support for Reboot and Power off for the
_platform_exit code.
Add _platform_exit mode handle
