*** ChibiOS next Release Notes. ***
|
|
******************************************************************************
|
|
|
|
ChibiOS next is composed of several independent but inter-operable
|
|
sub-projects: RT, NIL, HAL, EX. Plus several external libraries
|
|
integrated in our structure: WolfSSL, FatFS and lwIP.
|
|
|
|
*** ChibiOS next highlights ****
|
|
|
|
This release is focused on features and general improvements, HAL, RT and NIL
|
|
received a series of important improvements, new features have been added.
|
|
|
|
*** ChibiOS next general improvements ***
|
|
|
|
- WolfSSL 1.12.2 has been integrated. HTTPS demo added.
|
|
- FatFS 0.13 has been integrated.
|
|
- lwIP 2.0.3 has been integrated.
|
|
- CMSIS 5.1.1 has been integrated.
|
|
- Improved build system based on make.
|
|
- Improved integration with Eclipse, launch configurations have been
|
|
centralized for many projects.
|
|
- Several HAL and test applications have become "multi projects", a single
|
|
project is able to build for multiple targets/boards.
|
|
- Improved test engine.
|
|
- Added a test suite generator written in FTL, now it is possible to generate
|
|
test code without the need of SPC5Studio.
|
|
- Added a board files generator written in FTL, now it is possible to generate
|
|
board files without the need of ChibiStudio.
|
|
|
|
*** What's new in RT/NIL ports ***
|
|
|
|
- GHS compiler support added to the Power e200z port.
|
|
- Experimental ARM Cortex-A Trust Zone support.
|
|
|
|
*** What's new in OS Library ***
|
|
|
|
- OS library now has its own test suite.
|
|
- Mailbox API names changed by adding "Timeout" to those function that have
|
|
timeout capability, for consistency with the rest of the system.
|
|
- Added an "Objects Factory" to the OS Library, it allows to dynamically
|
|
allocate reference-counted kernel objects/buffers or to register
|
|
static objects. Allocated/registered objects can be retrieved by name.
|
|
- Added an "Objects FIFO" object to the OS Library, it allows to
|
|
exchange complex objects between threads/ISRs. It is based on a
|
|
mailbox and a guarded memory pool.
|
|
- Added alignment handling to memory pools.
|
|
- Added a new chGuardedPoolAllocI() API to the guarded memory pools.
|
|
|
|
*** What's new in RT 5.0.0 ***
|
|
|
|
- The type systime_t has been split in systime_t and sysinterval_t, the
|
|
two can have different size. The system is now more rigorous in time
|
|
handling, an absolute time is something different from an interval,
|
|
sysinterval_t can be larger than the systime_t, this means that it is
|
|
now possible to use very long intervals when the system time uses a small
|
|
counter.
|
|
- Time conversion macros have been renamed in TIME_S2I(), TIME_MS2I(),
|
|
TIME_US2(), TIME_I2S(), TIME_I2MS() and TIME_I2US. Conversion is now done
|
|
by casting all operands to a large time_conv_t type improving safety by
|
|
eliminating integer truncations.
|
|
- Time conversion functions have been renamed in: chTimeS2I(), chTimeMS2I(),
|
|
chTimeUS2I(), chTimeI2S(), chTimeI2MS() and chTimeI2US().
|
|
- New functions have been added for dealing with operations with time and
|
|
intervals: chTimeAddX() and chTimeDiffX().
|
|
- All functions that have a timeout parameter now take a sysinterval_t type
|
|
instead of systime_t.
|
|
- Improved test suite.
|
|
- Enhanced Events API, added chEvtGetAndClearEventsI() and chEvtAddEventsI().
|
|
- The chconf.h configuration files now are tagged with the version
|
|
number for safety. The system rejects obsolete files during
|
|
compilation. Stronger checks are performed on chconf.h, now missing
|
|
settings trigger an error instead of getting a default.
|
|
|
|
*** What's new in NIL 3.0.0 ***
|
|
|
|
- The type systime_t has been split in systime_t and sysinterval_t. The
|
|
system is now more rigorous in time handling, an absolute time is
|
|
something different from an interval.
|
|
- Time conversion macros have been renamed in TIME_S2I(), TIME_MS2I(),
|
|
TIME_US2(), TIME_I2S(), TIME_I2MS() and TIME_I2US. Conversion is now done
|
|
by casting all operands to a large time_conv_t type improving safety by
|
|
eliminating integer truncations.
|
|
- New functions have been added for dealing with operations with time and
|
|
intervals: chTimeAddX() and chTimeDiffX().
|
|
- All functions that have a timeout parameter now take a sysinterval_t type
|
|
instead of systime_t.
|
|
- Improved test suite.
|
|
- The chconf.h configuration files now are tagged with the version
|
|
number for safety. The system rejects obsolete files during
|
|
compilation.
|
|
|
|
*** What's new in HAL 6.0.0 ***
|
|
|
|
- Added a Managed Flash Storage module to the HAL. This modules handles
|
|
garbage collection, storage self-repair and wear leveling.
|
|
- Improved serial driver.
|
|
- Added a "control" function to the channels interface, it allows to add
|
|
custom features to the various implementations.
|
|
- Added I-class functions to the serial driver: sdGetI(), sdReadI(),
|
|
sdPutI() and sdWriteI().
|
|
- Improved PAL driver.
|
|
- Added an user parameter to the PAL callbacks for consistency with other
|
|
drivers.
|
|
- Added blocking functions for edge synchronization: palWaitLineTimeout()
|
|
and palWaitLineTimeoutS().
|
|
- Improved SPI driver.
|
|
- Now there are multiple modes for CS handling: by PAL pad (previous one), by
|
|
PAL line, by PAL port mask and LLD-specific.
|
|
- Added circular continuous mode to the SPI driver.
|
|
- Improved CAN driver.
|
|
- Added callback capability to the CAN driver. Now it is possible to use
|
|
callbacks in place of classic events.
|
|
- Improved USB driver.
|
|
- Added a usbWakeupHost() function for standby exit.
|
|
- Improved HAL queues to increase performance. Added new functions: iqGetI(),
|
|
iqReadI(), oqPutI() and oqWriteI().
|
|
|
|
*** What's new in EX 1.0.0 ***
|
|
|
|
- No changes.
|
|
|
|
*** What's new in AVR HAL support ***
|
|
|
|
- Added initial ATtiny167 support.
|
|
- Added initial ATXmega128a4u support.
|
|
- Improvement of SPI, EXT, PAL low level drivers.
|
|
|
|
*** What's new in STM32 HAL support ***
|
|
|
|
- Updated SPI drivers to implement the new circular mode of the HAL SPI
|
|
driver model.
|
|
- Updated STM32F1xx headers to 1.6, STM32F3xx to 1.9, STM32L0xx to 1.10,
|
|
STM32L4xx to 1.9, STM32H7xx to 1.1.
|
|
- Implemented PAL enhancements in GPIOv1, GPIOv2 and GPIOv3 implementations.
|
|
- Modified the STM32 OTGv1 driver to work without pump thread, transfers
|
|
are now done in the ISR. The driver is now greatly simplified.
|
|
- Added STM32L496xx/STM32L4A6xx support.
|
|
- Added STM32F030x4 support.
|
|
- Added initial STM32H7xx support.
