*** Releases and Change Log ***
*****************************************************************************
*** Next ***
- NEW: Now RT virtual timers can recalculate the value of CH_CFG_ST_TIMEDELTA
at runtime and continue using the recalculated value. This has two
consequences: 1) The value is recalculated once 2) it is possible
to use the new API chVTGetCurrentDelta() and update the static
setting in order to avoid recalculation.
- NEW: OSLIB release methods now return the value of the reference counter.
- NEW: Support for STM32C0xx.
- NEW: Improved DAC driver, updated STM32 DACv1.
- NEW: STM32 RTCv2 and RTCv3 modified to not use shadow registers.
- NEW: Enhanced STM32F7xx MPU configuration in mcuconf.h.
- NEW: I2C slave support in HAL high level driver.
- NEW: Added settings for STM32 OCTOSPIv1 and OCTOSPIv2 TCR bits SSHIFT and
DHQC.
- NEW: Automatic removal of duplicated inclusion paths on make command lines.
- NEW: Reworked STM32 SDMMCv1 and SDMMCv2 drivers, better timeout and clock
handling, improved speed for aligned buffers.
- NEW: Added a "waend" field to the thread structure in RT for debug
convenience.
- NEW: Added a para-virtualized HAL port for use in sandboxes.
- NEW: Added a VIO subsystem to sandboxes supporting drivers
para-virtualization, PAL and SIO supported so far.
- NEW: Added and RT port for use in virtualized sandboxes.
- NEW: Added full virtualization support to sandboxes with a virtual IRQ
mechanism.
- NEW: Added __CH_OWNEROF() macro to RT.
- NEW: Added a Posix-favored shell named "msh" (Mini Shell). The shell is able
to run sub-apps inside the same sandbox. The shell can either be placed
statically in flash or loaded dynamically in RAM.
- NEW: Added runnable "apps" capability to SBs, apps available so far: msh, ls.
- NEW: Added ability to load ELF files to SBs.
- NEW: Enhanced Posix API for SBs leveraging the VFS integration.
- NEW: SBs and VFS integration. Each SB can see its own VFS instance.
- NEW: Added integration of LittleFS on top of our flash infrastructure.
- NEW: Added a new MEM_IS_VALID_FUNCTION() macro to RT and NIL.
- NEW: Changed SB configuration options names to be prefixed with SB_CFG_.
- NEW: Added a new CH_CFG_HARDENING_LEVEL option to RT.
- NEW: Added a chXXXDispose() function to all objects in NIL.
- NEW: Added a chXXXDispose() function to all objects in RT.
- NEW: Added VFS-related commands to the shell, disabled by default.
- NEW: Added a new VFS subsystem (Virtual File System), it allows to assemble
trees of files from multiple "File System Drivers" into a single tree
and access it as a whole.
- NEW: Added MEM_NATURAL_ALIGN macro to RT and NIL.
- NEW: Added static initializer for virtual timers in RT.
- NEW: Added new function chHeapIntegrityCheck().
- NEW: Function chCoreGetStatusX() changed to return a memory region object
instead of a simple size.
- NEW: RT and NIL upgraded to support the enhanced OSLIB.
- NEW: Memory areas/pointers checker functions added to OSLIB.
