(backported to 2.4.3).
- FIX: Fixed double definition of sd1fel and sd2fel breaks Posix simulator
(bug 3570532).
- FIX: Fixed Ethernet PHY power down scheme prevents using LAN8720A (bug
3570335).
- FIX: Fixed FatFS won't compile with _FS_REENTRANT enabled (bug 3570135)
(backported to 2.4.3).
- FIX: Fixed mmc_spi.c won't compile due to misplaced declaration (bug
3570035)(backported to 2.4.3).
- FIX: Fixed problem in STM32F1xx USB driver after revision 4598 (bug 3569374).
- FIX: Fixed GPIO glitch during PAL initialization (bug 3569347)(backported
to 2.4.3).
- FIX: Fixed FatFS timestamp incorrect (bug 3568626).
- FIX: Fixed Data available event not generated in serial_usb driver (bug
3567992).
- FIX: Fixed STM32F1x rtc_lld_init glitches rtc on hard reset (bug 3567597)
(backported to 2.4.3).
- FIX: Fixed STM8L, cosmic compiler: c_lreg not saved (bug 3566342)(backported
to 2.2.10 and 2.4.3).
- NEW: Updated STM32F1, F2, F4, L1 ADC drivers to allow HW triggering.
- NEW: Added a new option STM32_ETH1_CHANGE_PHY_STATE to the STM32 MAC driver,
this change is connected to bug 3570335.
- NEW: Modified the CAN drivers to use the new event flags mechanism, the
previous flags handling has been removed.
- NEW: Modified serial and serial_usb drivers to use the new event flags
mechanism, the previous flags handling in BaseAsynchronousChannel has
been removed.
- NEW: Improved the kernel events subsystem, now event sources can associate
source-specific flags to the listener, the flags can then be retrieved
using the new APIs chEvtGetAndClearFlags() and chEvtGetAndClearFlagsI().
Some old APIs have been renamed to increase consistency of the module.
- NEW: Added VLE support to the Power Architecture GCC port.
- NEW: Reorganized the Power Architecture GCC port along the lines of the
ARMCMx port, now it can support multiple core types.
- NEW: Updated the Power Architecture rules.mk file to put object and listing
files into a ./build directory like ARM ports already do.

- NEW: Added an abstract interface for block devices in the HAL. This
abstraction layer is meant to unify the access protocol to the SDC and
MMC_SPI (and potentially others) device drivers.
- NEW: Added an abstract interface for serial devices in the HAL. This
interface is meant to replace the equivalent class already present in the
kernel. access macros are similar except for the prefix, "chn" instead
of "chIO".
- NEW: Updated the MSP port to work with the latest MSPGCC compiler (4.6.3
LTS 20120406 unpatched), now the old MSPGCC 3.2.3 is no more supported
(backported to 2.4.1).

not in lock mode. This change reduces the interrupt jitter caused by
multiple timers used at same time.
- NEW: Added board files and demo for Olimex LPC-P1343 (contributed by
Johnny Halfmoon).
- NEW: Added handling of input 2 to the STM32 ICU driver (contributed by
Fabio).
- NEW: STM32 Ethernet driver completed. Added STM32F107 and STM32F407
lwIP demos (backported to 2.4.1).
- NEW: lwIP related code is not centralized into a single place, no need to
duplicate the code in each application or demo (backported to 2.4.1).
- CHANGE: Added two new methods to the BaseSequentialStream interface:
chSequentialStreamPut() and chSequentialStreamGet().
- CHANGE: Removed the chioch.h header from the kernel, now channels interface
is exported by the HAL. Removed functions chPutWouldBlock() and
chGetWouldBlock().
- CHANGE: Removed macro chMsgGetS(), chMsgGet() is still available.
- CHANGE: chprintf() now takes a BaseSequentialStream as parameter instead
of a BaseChannel making it more generic.
- CHANGE: Now the shell requires a BaseSequentialStream instead of a
BaseChannel for communications making it more generic.
- CHANGE: Kernel memory pools now do not check the alignment of the inserted
objects, it is responsibility of the application to insert properly
aligned objects.
- CHANGE: The PORT_INT_REQUIRED_STACK parameter for the Cortex-Mx ports has
been increased to 32 from 16 because the stack frame sizes are increased
when compiling with optimizations disabled, which is common during
debugging. In order to save RAM trim back this value when compiling with
optimizations enabled (backported to 2.4.1).
- CHANGE: Renamed Ethernet driver in AT91 HAL ETHD1 (backported to 2.4.1).
- CHANGE: Macros icuGetWidthI() and icuGetPeriodI() renamed to icuGetWidth()

various STM32 sub-families.
- NEW: New DMA helper driver for STM32, it simplifies the use of the DMA
resources and hides most differences with the new enhanced DMA units
found in the STM32F2xx sub-family.
- NEW: Now an error is generated at compile time when trying to enable the
options CH_DBG_ENABLE_STACK_CHECK on ports that do not support it.
- NEW: Added a kernel-only Cortex-Mx demo as reference project for users not
interested in the HAL but just want to use the ChibiOS/RT kernel.
The demo is named ARMCM3-GENERIC-KERNEL and is defaulted to the STM32, in
order to use it on other families or on the ARM Cortex-M0 just change the
inclusion paths in the makefile.
- NEW: Integrated new FatFs version 0.8b.
- NEW: Added a new hook THREAD_CONTEXT_SWITCH_HOOK() that allows to insert
code just before a context switch. For example this hook could be used
in oder to implement advanced power management schemes.
- NEW: Added a new debug option CH_DBG_SYSTEM_STATE_CHECK that ensures the
correct API call protocol. If an API is invoked out of the correct context
then the kernel panics with a debug message.
- NEW: The ARMCMx startup file (crt0.c) now is able to fill the stack areas
with a filler (default behavior). This is required in order to easily assess
the stack usage at runtime.
- NEW: Added the new CMSIS 2.1 headers, now CMSIS resides into a shared
location: ./os/ports/common/ARMCMx/CMSIS. Old CMSIS files have been
removed from the various platforms.
- NEW: Removed all the ch.ld files from the ARMCMx demos, now the makefiles
point to common ld files under the various ports. Less duplication and
easier maintenance.
- NEW: Improved stack checking and reorganized memory map for the Cortex-Mx
demos. Now stacks are allocated at the start of the RAM, an overflow of the
exception stack now triggers an exception (it could go unnoticed before).
The process stack is organized to be checked on context switch like other
threads. Now all threads have an explicit stack boundary pointer.
- NEW: Added debug plugin for Eclipse under ./tools/eclipse (backported to
2.2.7).
- NEW: The debug macros chDbgCheck() and chDbgAssert() now can be externally
redefined. The macro chDbgCheck() no more includes the line number in the
description because incompatibility with the Cosmic compiler (backported to
2.2.7).
- NEW: Added provisional support for STM32F2xx. Because of this some
directories related to the STM32 have been renamed, your makefiles may
require adjustments.
- NEW: Added a custom rule to the various rules.mk files, now it is possible
to add an user rule into the Makefiles.
- NEW: Improvements to the trace buffer, now it stores a full thread pointer
and event time, changed names to debug variables by adding the "dbg_"
prefix (backported to 2.2.7).
- NEW: Added a new functionality to the registry subsystem, now it is possible
to associate a name to the threads using chRegSetThreadName. The main and
idle threads have their name assigned by default (backported to 2.2.7).
- NEW: Added TIM8 support to the STM32 GPT, ICU and PWM drivers.
- NEW: Updated the STM32 header file to the latest version 3.5.0 and fixed
it in order to correct several bugs related to the XL family.
- NEW: Added a chprintf() function to ./os/various, it can print on any
BaseChannel.
- NEW: Improved the mini shell, enhanced info command, optimizations and
removed the shellPrint() and shellPrintLine() functions, now it uses
chprintf() for output.
- NEW: lwIP 1.4.0 has been integrated, this new version does not require
custom hooks into the Thread structure and is thus much lighter.
- NEW: FatFs demo for the STM32F103ZG using the SDC driver.
- NEW: Now the STM32 SDC driver supports unaligned buffers transparently.
Optimized the driver for single block read and write operations. Optimized
the driver state machine.
- NEW: Finished the reorganization of the Cortex-Mx ports, now also the
IAR and RVCT ports support the new Compact mode.
- NEW: Added to the ARMv6-M sub-port an option to use the PendSV exception
instead of NMI for preemption (backported to 2.2.5).
- NEW: Reorganization of the Cortex-Mx ports in order to reduced code and
comments duplication in the various headers (backported to 2.2.5).
- NEW: Improved the ARMv7-M sub-port now there are two modes: Compact and
Advanced.
The advanced mode is equivalent to the previous versions, the compact mode
is new and makes the kernel *much* smaller and generally faster but does
not support fast interrupts (backported to 2.2.5).
- NEW: Now the port layer exports info regarding the compiler and the port
options. The info are printed into the test reports. Date and time also
added.
- CHANGE: Removed the option CH_USE_NESTED_LOCK, lwIP no more requires it and
it would have conflicted with CH_DBG_SYSTEM_STATE_CHECK which is far more
useful.
- CHANGE: Renamed the scheduler functions chSchIsRescRequiredExI() to
chSchIsPreemptionRequired(), chSchDoRescheduleI() to chSchDoReschedule(),
chSysSwitchI() to chSysSwitch(). All those functions were special cases
and not regular I-class APIs.
- CHANGE: Renamed the macros IDLE_THREAD_STACK_SIZE and INT_REQUIRED_STACK
to PORT_IDLE_THREAD_STACK_SIZE and PORT_INT_REQUIRED_STACK for consistency.
- CHANGE: Removed the "old" Cortex-M3 port from the code, the current port
has no drawbacks and the old port is now just a maintenance cost.
- CHANGE: Removed the CH_CURRP_REGISTER_CACHE option, it is GCC-specific so
it does not belong to the kernel options. The feature will be eventually
reimplemented as a port-specific option.
- CHANGE: chiQGetFullI() and chOQGetFullI() become macros. The queues
subsystem has been optimized and is no more dependent on semaphores.
Note that the queues callbacks invocation policy has been slightly
changed, see the documentation (backported to 2.2.4).

as default.
- CHANGE: Removed all the prefixes from the structure/union field names
in the HAL subsystem.
- CHANGE: Updated the documentation to use Doxygen 1.7.4 which produces a much
more readable output. Also modified the documentation layout to put functions
and variables ahead of everything else in the group pages.

LPC11xx. The test demonstrates the system stability in a thread-intensive,
progressively CPU-saturating, IRQ-intensive long duration test.
- NEW: Added two new functions to the events subsystem: chEvtBroadcastFlags()
and chEvtBroadcastFlagsI(). The old chEvtBroadcast() and chEvtBroadcastI()
become macros. The new functions allow to add the same flags to all the

to 2.0.9).
- NEW: New ARM Cortex-Mx port for RVCT compiler.
- NEW: Integrated the various Cortex-Mx GCC, IAR and RVCT demos in unified
demos with multiple project files, the code is exactly the same. Renamed
the directories removing the compiler suffix.
- NEW: Added an USB clock configuration in the STM32 HAL driver (LD, MD, HD).
- NEW: New semaphore API chSemSetCounterI().
- NEW: New queue APIs chIQGetFullI() and chOQGetFullI().
- CHANGE: Serial drivers now have a single event source instead of three,
the event source is located in the superclass, this allows to create
alternative implementations of the serial driver while keeping compatibility,
the change also allowed to save 8/4 RAM bytes per serial driver.
- CHANGE: Modified the ADC and CAN drivers to allow a NULL pointer for
the configuration structure if it is not required by the implementation.
- CHANGE: Modified the MMC_SPI driver to *require* a NULL as pointer to
the configuration.
- CHANGE: Removed enforced inlining for the chSchReadyI() function when
the CH_OPTIMIZE_SPEED is enabled. Now the matter is left to the compiler
specific settings. This change is meant to increase compatibility with
compilers that have a different inlining semantic than GCC when not in
C99 mode.
- CHANGE: Changed the declaration of the main() function in all demos
without arguments. Removed the clearing of arguments from the startup
files and saved some space.

- CHANGE: Changes in the board files organization, now the board
initialization is invoked from within halInit() after all the device
drivers have been initialized. Now applications are required to
explicitly invoke halInit() and chSysInit() from within their main().
- CHANGE: Removed the CMSIS files from the ARMCMx port, added the headers
into the various HAL platforms requiring them. The change is required
because the port layer must not have vendor specific dependencies and
there is the possibility that the various vendors would use different
CMSIS versions now that CMSIS 2.x has been released.
- CHANGE: Modified the start of the ADC in the STM32 ADC driver, now it is
no more required to specify ADC_CR2_EXTSEL_SWSTART and ADC_CR2_CONT
in the CR2 register configuration. Also reordered the start sequence
in order to allows a longer stabilization time for the ADC.
- Documentation improvements.

time now it is possible to test the presence of any single peripheral into
the specified STM32 device.
- CHANGE: Separated dynamic threads code into dedicated files: chdynamic.c
and chdynamic.h.
- CHANGE: Moved the declaration of the variable pal_default_config from
hal_lld.c to the various board.c. That structure is more meaningful in
