First release under the new version numbering system. This point release includes a lot of fixes and enhancements, the result of 6 months of development. See the release notes for more details:
ChibiOS 16.1.0 is composed of several independent but inter-operable sub-projects: RT, NIL, HAL.
*** ChibiOS 16.1.0 highlighs ****
This release has been developed with focus mainly on the HAL subsystem and general STM32 support. RT and NIL received minor bug fixes that have also been back-ported to previous stable branches.
*** ChibiOS 16.1.0 general improvements ***
- ChibiOS release version number redefined as <year>.<month>.<patch> in order to not confuse release version numbers with products version numbers. - Improved ARMCMx GCC rules.ld supporting multiple RAM regions. It is now possible to assign stacks, data, bss, etc ot any of the defined RAM regions. - Added capability to allocate initialized, zeroed and not initialized data to any of the defined RAM regions.
*** What's new in RT 3.1.0 ***
- Support for Cortex-M7. - Added new function chVTGetTimersStateI() returning the state of the timers list. This is useful to assess if it is convenient to transition to lower power modes. - Added CodeWarrior compiler support to the e200 port. - Minor bugs fixed.
*** What's new in HAL 4.0.0 ***
- New watchdog (WDG) driver. - Added support for STM32L0xx, STM32L4xx, STM32F7xx, STM32F446, STM32F030xC, STM32F070x6, STM32F070xB, STM32F091xC, STM32F098xx devices. - Improved USB driver. - Modified the driver to have a separate USB_SUSPENDED state, this allows the application to detect if the USB is communicating or if it is disconnected or powered down. - Added synchronous API. - Removed queued API. - Improved USB support for STM32 USBv1, OTGv1. - Isochronous support for STM32 USBv1, OTGv1. - STM32 USBv1/OTGv1 buffers and queues do not more require to be aligned in position and size. - Improved Serial-USB driver. - New buffers queue object. - Modified the driver to reject write/read attempts if the underlying USB is not in active state. In case of disconnection the SDU driver broadcasts a CHN_DISCONNECTED event. - Improved CAN driver. - Better errors reporting for STM32 CANv1. - Improved UART driver. - Added synchronous API. - Improved PAL driver. - Added "lines" handling to PAL driver, lines are identifiers of both ports and pins encoded in a single value. Added a set of macros operating on lines. - Added GPIOv3 driver for STM32L4xx. - I2S support added for STM32 SPIv2 peripheral. - Board files an demos for STM32 Nucleo32 boards. - Added latest CMSIS headers for all STM32 families. - STM32 DMA drivers have been unified and consolidated in DMAv1 and DMAv2. - DMA channels selection now supported on all devices with the new mux mechanism. - Added serial driver support for USART 3..6 on STM32F030xC devices. - Added support for differential mode to the STM32F3xx ADC driver. - STM32 GPT, ICU and PWM driver enhancements. Now it is possible to suppress default ISRs by defining STM32_TIMx_SUPPRESS_ISR. The application is now able to define custom handlers if required or simply save space if the driver callbacks are not used. Now the functions xxx_lld_serve_interrupts() have global scope, this way custom ISRs can call them from outside the driver module. - Added TIM units use cross-check in STM32 GPT, ICU, PWM and ST drivers, now use collisions are explicitly reported. - Added support for I2C3 and I2C4 to the STM32 I2Cv2 I2C driver. - Added support for SPI4...SPI6 to the STM32 SPIv2 SPI driver. - Added support for UART4...UART8 to the STM32 UARTv2 UART driver. - Added support for UART7 and UART8,LPUART1 to the STM32 UARTv2 serial driver. - New STM32 ADCv3 driver supporting middle STM32 devices (F3, L4). - New STM32 ADCv2 driver supporting large STM32 devices (F2, F4, F7). - New STM32 ADCv1 driver supporting small STM32 devices (F0, L0). - Introduced support for TIM21 and TIM22 in STM32 ST driver.
*** 16.1.1 *** - NIL: NIL_CFG_USE_EVENTS not properly checked in NIL (bug #694). - RT: Fixed ISR statistics are not updated from a critical zone in RT (bug #693). - NIL: Fixed NIL test suite calls I and S functions outside critical zone (bug #692). - NIL: Fixed protocol violation in NIL OSAL (bug #691). - HAL: Fixed error in HAL buffer queues (bug #689). - RT: Fixed tm_stop - best case bug (bug #688). - RT: Several minor documentation/formatting-related fixes.
*** 16.1.2 *** - VAR: Fixed missing time conversion in lwIP arch module (bug #696). - HAL: Fixed incorrect handling of TIME_IMMEDIATE in the HAL buffer queues (bug #695).
ChibiOS 16.1.4 has been released. It is a recommended update because two tickets are marked "high". It includes: - HAL version 4.0.4. - NIL version 1.1.2. - RT version 3.1.3.
ChibiOS 16.1.8 has been released. It is a recommended update because a good number of minor problems and a significant issue in RT mailboxes have been fixed .
It includes: - HAL version 4.0.8. - NIL version 1.1.3. - RT version 3.2.0.
