 ChibiOS next is composed of several independent but inter-operable

-sub-projects: RT, NIL, HAL.

+sub-projects: RT, NIL, HAL, EX.

 

 *** ChibiOS next highlights ****

 

 This release is focused on RTOS general improvements, both RT and NIL received

 *** ChibiOS next general improvements ***

 

-- Rationalized source tree to reduce code duplication.

+- Shared licensing headers under /os/licenses, now all products are handled

+  by the same license include files.

+- New ChibiOS/EX subsystems. EX sits on top of HAL and provides portable

+  drivers for devices residing the MCU like MEMS, sensors, memories,

+  displays etc.

 - Shared RTOS components, now allocators, mailboxes and binary semaphores

   are usable by both RT and NIL.

-- Shared ports architecture. Now RTOS ports work for both RT and NIL, no

-  more duplication.

+  - Memory Pools now have a new variant named "Guarded Memory Pool" including

+    a semaphore that guards the allocation function, the caller waits if there

+    is not an object available in the pool.

+- FatFS 0.10b has been integrated.

+- Rationalized source tree to reduce code duplication.

+- New unit test library.

+- Test suites have been rewritten using an unique code generation system

+  starting from XML descriptions.

+- Startup files have been separated from ports and licensed under Apache 2.0

+  license, now it is possible to use ChibiOS startups and ld files in projects

+  without RT, NIL, HAL or EX.

+- Improved GCC ld scatter files with multi RAM/Flash regions capability.

+- GCC makefiles system improvements.

+- Support for all new Nucleo and Discovery boards from ST.

+- CMSIS updated to version 4.50.

+- Enhanced shell with history and quoted parameters. Common commands have

+  beed included in a shared module in order to avoid duplication in the

+  various demos.

+

+*** What's new in RT/NIL ports ***

+

+- Common ports architecture. Now RTOS ports work for both RT and NIL, no

+  more code duplication. Ports are now also licensed for both NIL and RT.

 - MPU use for hardware stack checking in ARMCMx port.

-- Enhanced shell.

 

 *** What's new in RT 4.0.0 ***

 

-- Common ports architecture.

-- Ability to use the new shared RTOS components.

+- Now uses the common ports architecture.

+- Now uses the new shared RTOS components.

 - New threading API, now creating static threads is even faster.

 - Extended priority range from 1..127 to 1..255.

 - Enhanced dynamic threading, safer and easier to use.

   but also IRQs, halts and user events. The trace record now stores both the

   "slow" system time and a RT stamp for increased accuracy.

 - New kernel hooks for a more flexible code instrumentation.

+- Removed I/O queues, now the HAL has an improved equivalent.

 - Experimental NASA OSAL implementation.

 

-*** What's new in HAL 4.1.0 ***

+*** What's new in NIL 2.0.0 ***

 

+- Now uses the common ports architecture.

+- Now uses the new shared RTOS components.

+- All new features are optional so there is no code size increase.

+- Enhanced source-level compatibility with RT.

+- Enhanced debug features.

+  - State checker like in RT.

+  - Parameters checks like in RT.

 

-*** What's new in NIL 2.0.0 ***

+*** What's new in HAL 5.0.0 ***

 

-- Common ports architecture.

-- Ability to use the new shared RTOS components.

-- State checker.

-- Parameters checks.

+- Improved serial driver.

+  - It is possible to set a different buffer size for each port.

+  - SW overruns and HW overruns now have a separate event flag.

+- Events handling in the PAL driver. Now it is able to support interrupts

+  handling and callbacks.

+- EXT driver is still supported but marked as deprecated.

+- New interface for flash devices (used by EX).

+- New interfaces for accelleromet, barometer, compass, gyroscope,

+  hygrometer and thermometer devices (used by EX).

+- Added an I2C bit banged driver as fallback for faulty hardwares.

+- Improved OSAL architecture with shared sub-modules.

+- All file names have been prefixed by "hal_" in order to prevent collisions

+  with 3rd parties files. This should make integration of external libraries

+  much easier.

+- Improved behavior of HAL queues, now the timeout is absolute not just an

+  inter-byte timeout.
