* WIP on stripping fw * Compact FW build - use RAM_EXEC=1 COMPACT=1 DEBUG=0 * Fixed uninitialized storage struct; small fixes to compact fw * Flasher srv w/mocked flash ops * Fixed typos & accomodated FFF changes * Alternative fw startup branch * Working load & jmp to RAM fw * +manifest processing for stage loader; + crc verification for stage payload * Fixed questionable code & potential leaks * Lowered screen update rate; added radio stack update stubs; working dfu write * Console EP with manifest & stage validation * Added microtar lib; minor ui fixes for updater * Removed microtar * Removed mtar #2 * Added a better version of microtar * TAR archive api; LFS backup & restore core * Recursive backup/restore * LFS worker thread * Added system apps to loader - not visible in UI; full update process with restarts * Typo fix * Dropped BL & f6; tooling for updater WIP * Minor py fixes * Minor fixes to make it build after merge * Ported flash workaround from BL + fixed visuals * Minor cleanup * Chmod + loader app search fix * Python linter fix * Removed usb stuff & float read support for staged loader == -10% of binary size * Added backup/restore & update pb requests * Added stub impl to RPC for backup/restore/update commands * Reworked TAR to use borrowed Storage api; slightly reduced build size by removing `static string`; hidden update-related RPC behind defines * Moved backup&restore to storage * Fixed new message types * Backup/restore/update RPC impl * Moved furi_hal_crc to LL; minor fixes * CRC HAL rework to LL * Purging STM HAL * Brought back minimal DFU boot mode (no gui); additional crc state checks * Added splash screen, BROKEN usb function * Clock init rework WIP * Stripped graphics from DFU mode * Temp fix for unused static fun * WIP update picker - broken! * Fixed UI * Bumping version * Fixed RTC setup * Backup to update folder instead of ext root * Removed unused scenes & more usb remnants from staged loader * CI updates * Fixed update bundle name * Temporary restored USB handler * Attempt to prevent .text corruption * Comments on how I spent this Saturday * Added update file icon * Documentation updates * Moved common code to lib folder * Storage: more unit tests * Storage: blocking dir open, differentiate file and dir when freed. * Major refactoring; added input processing to updater to allow retrying on failures (not very useful prob). Added API for extraction of thread return value * Removed re-init check for manifest * Changed low-level path manipulation to toolbox/path.h; makefile cleanup; tiny fix in lint.py * Increased update worker stack size * Text fixes in backup CLI * Displaying number of update stages to run; removed timeout in handling errors * Bumping version * Added thread cleanup for spawner thread * Updated build targets to exclude firmware bundle from 'ALL' * Fixed makefile for update_package; skipping VCP init for update mode (ugly) * Switched github build from ALL to update_package * Added +x for dist_update.sh * Cli: add total heap size to "free" command * Moved (RAM) suffix to build version instead of git commit no. * DFU comment * Some fixes suggested by clang-tidy * Fixed recursive PREFIX macro * Makefile: gather all new rules in updater namespace. FuriHal: rename bootloader to boot, isr safe delays * Github: correct build target name in firmware build * FuriHal: move target switch to boot * Makefile: fix firmware flash * Furi, FuriHal: move kernel start to furi, early init * Drop bootloader related stuff * Drop cube. Drop bootloader linker script. * Renamed update_hl, moved constants to #defines * Moved update-related boot mode to separate bitfield * Reworked updater cli to single entry point; fixed crash on tar cleanup * Added Python replacement for dist shell scripts * Linter fixes for dist.py +x * Fixes for environment suffix * Dropped bash scripts * Added dirty build flag to version structure & interfaces * Version string escapes * Fixed flag logic in dist.py; added support for App instances being imported and not terminating the whole program * Fixed fw address in ReadMe.md * Rpc: fix crash on double screen start * Return back original boot behavior and fix jump to system bootloader * Cleanup code, add error sequence for RTC * Update firmware readme * FuriHal: drop boot, restructure RTC registers usage and add header register check * Furi goes first * Toolchain: add ccache support * Renamed update bundle dir Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com> Co-authored-by: あく <alleteam@gmail.com>
