| NuttX-7.16 Release Notes |
| ------------------------ |
| |
| The 116th release of NuttX, Version 7.16, was made on June 1, 2016, |
| and is available for download from the Bitbucket.org website. Note |
| that release consists of two tarballs: nuttx-7.16.tar.gz and |
| apps-7.16.tar.gz. These are available from: |
| |
| https://bitbucket.org/nuttx/nuttx/downloads |
| https://bitbucket.org/nuttx/apps/downloads |
| |
| Both may be needed (see the top-level nuttx/README.txt file for build |
| information). |
| |
| Additional new features and extended functionality: |
| |
| * Core OS: |
| |
| - Power Management: Add activity domain to all PM interfaces and |
| driver callbacks. If CONFIG_PM_NDOMAINS == 1, then the legacy |
| behavior is preserved. If CONFIG_PM_NDOMAINS > 1, then multiple |
| PM domains are supported. This will allow separate control for |
| certain power management groups. For example, a network can be |
| shut down without affect an ongoing UI (and vice versa). |
| - board_app_initialize(): board_app_initialize() now accepts an |
| argument that may be used to support initialization in different |
| configurations. |
| |
| * File System and Block and MTD Drivers: |
| |
| - N25Qxxx: Add MTD support for Micron N25Qxxx family of QSPI flash. |
| From Dave (ziggurat29). |
| - SST26F: Add an MTD driver for SST26F spi/qspi flash devices (SPI |
| mode only). From Sebastien Lorquet. |
| - File Descriptor Detach: Add logic to detach a file structure from a |
| file descriptor. This is for use only within the OS. It permits an |
| open file or driver to be used across multiple threads. |
| |
| * Networking and Network Drivers: |
| |
| - listen()/accept(): Separate out psock_listen() and psock_accepti() |
| for internal, thread independent OS usage (i.e., without a socket |
| descriptor). |
| - VNC Server: Add support for a VNC server. This logic is code |
| complete and functional, but not well tested. |
| |
| * Graphics and Graphic Drivers: |
| |
| - Framebuffer driver: Add a display number to each interface in order |
| to support multiple display devices. |
| - VNC Server: Add support for a VNC server. This logic is code |
| complete and functional, but not well tested. |
| - LCD Backpack: Add support for PCF8574 LCD Backpack driver. This |
| driver supports an interface board that is based on the PCF8574 I/O |
| expander and supports the HD44780-based (or compatible) LCD modules. |
| There are a myriad of different vendors of such, but they are |
| principally the same, save wiring and minor features like jumpers |
| for I2C addresses. This driver supports known and unknown variants. |
| From Dave (ziggurat29). |
| |
| * Common Device Drivers: |
| |
| - RTC: Simplify the RTC interface. The old interface was way too |
| complex and was not fully implemented anywhere. |
| - BH1750FVI: Add a character driver for Rohm Ambient Light Sensor |
| BH1750FVI. From Alan Carvalho de Assis. |
| - CAN: Improve CAN error reporting. From Frank Benkert. |
| - aes.h: Modifications to the crypto API needed for LPC43xx. From |
| Alexander Vasiljev. |
| - ADC: Interface no longer uses global adc_receive() call. Added a |
| new bind() method to the ADC interface. Now the ADC upper half |
| driver will register its receipt-of-data callback. This change |
| allows the ADC lower half driver to be used with a differ ADC upper |
| half. |
| |
| * Simulation Platform: |
| |
| - Linux Host Networking: Enhance networking support for the |
| simulation under Linux. Includes updated support for Linux TUN/TAP, |
| and the addition of support for Linux bridge devices. From Steve. |
| |
| * ARMv7-A, ARMv7-R, and ARMv7-M: |
| |
| - ARMv7-M: Convert more assembly language files for use with the IAR |
| toolchain. From Kha Vo. |
| - ARMv7-A: Complete re-design of SMP-related logic to initialize each |
| CPUn, n > 0, when CONFIG_SMP=y. |
| |
| * Atmel SAMV7: |
| |
| - Add a JTAG config and ERASE config to Kconfig to set the |
| CCFG_SYSIO SYSIO Pins. From David Sidrane. |
| - System Reset: Add the up_systemreset interface to the samv7 arch. The |
| approach is slightly different in that: 1) It enables ARCH_HAVE_RESET |
| and allows the user to set if, and for how long, to drive External |
| nRST signal. It also does not contain a default board_reset, as that |
| really should be done in the config's src if CONFIG_BOARDCTL_RESET |
| is defined. From David Sidrane. |
| |
| * Atmel SAMV7 Boards: |
| |
| - SAMV71-XULT: Add configuration(s) that were be used to verify VNC |
| graphics output as well as mouse and keyboard input. |
| |
| * NXP Freescale i.MX6 Boards: |
| |
| - Sabre-6Quad: The basic i.MX6 port is complete. This is a minimal |
| port at present and probably still has some as-of-yet-undiscovered |
| issues. |
| - Sabre-6Quad: Basic SMP NSH configuration is now working. But this |
| is probably only because the SMP test case does not stress the |
| logic. There are know outstanding SMP issues as noted in the |
| Sabre-6Quad README.txt file. |
| |
| * NXP Freescale LPC43xx: |
| |
| - LPC4337jet100: Add definitions for the LPC4337jet100 chip. From |
| Alexander Vasiljev. |
| |
| * NXP Freescale LPC43xx Drivers: |
| |
| - AES: Add AES support. From Alexander Vasiljev. |
| |
| * STMicro STM32: |
| |
| - STM32 L4: Add configuration options to allow SRAM2 to be used for |
| heap, or not at all, and to zero-initialize it on OS start, or not |
| at all. From Dave dev@ziggurat29.com. |
| - STM32 L4: Add support for HSE and MSI clocks, and auto trim of MSI |
| to LSE (needed for USB). From Dave (ziggurat29) |
| - STM32 L4: Add support for unique id function to arch; modified board |
| to support unique id boardctl. From Dave (ziggurat29) |
| |
| * STMicro STM32 Drivers: |
| |
| - STM32 F4 RTC: Add a custom RTC driver with support for alarms. From |
| Neil Hancock. |
| - STM32 L4 QSPI: Add a QSPI driver with DMA support and (optional |
| memory mapped mode support. From Dave ziggurat29). |
| - STM32, STM32 L4, and STM32 F7 Serial: Add support for compliant |
| SD-style breaks. From David Sidrane. |
| - STM32 L4 CAN: Add CAN support for STM32L4. From Sebastien Lorquet. |
| - STM32 1-Wire: Add support for a custom 1-wire driver. The serial |
| driver already supports a 1-wire interface, but this driver uses the |
| same serial logic to implement a lower half driver much like the |
| I2C lower half driver. From Aleksandr Vyhovanec. |
| - STM32 L4 SPI: Add support for SPI 4 and 5 on stm32f411 chips. From |
| Konstantin Berezenko. |
| - STM32 ADC: Allow omitting use of channels in a lower part of PWM. |
| From Pierre-noel Bouteville. |
| - STM32 L4 I2C: Get I2C working for STM32L4. From Dave (ziggurat29). |
| |
| * STMicro STM32 Boards: |
| |
| - STM3220G-EVAL: Add support for both the IAR and uVision GCC IDEs. |
| From Kha Vo. |
| - STM32F429I Discovery: Add support for the uVision GCC IDE. From |
| Kha Vo. |
| - STM32F4 Discovery: Integrate BH1750FVI driver in the STM32F4 Discovery |
| board. From Alan Carvalho de Assis. |
| - STM32L476VG Discovery: Add support for QSPI based N25Qxxx flash. |
| From Dave (ziggurat29) |
| - STM32L476VG Discovery: Add board ioctls for allowing user application |
| to cause QSPI memory mapped mode to be engaged and disengaged. Also |
| partitioned QSPI flash for file system and other (eventually xip). |
| From Dave (ziggurat29) |
| - Nucleo-144: Basic port for the Nucleo-144 board with the STM32F746ZG |
| MCU. From Kconstantin Berezenko. |
| - STM32F103 Minimum: Add support for this minimual STM32F103CBT6 "blue" |
| board. From Alan Carvalho de Assis. |
| - STM32F411E Discovery: Add basic configuration for stm32f411e-disco |
| board with STM32F411VE chip. From Konstantin Berezenko. |
| |
| * Build/Configuration System: |
| |
| - Moved NuttX repository to https://bitbucket.org/nuttx/nuttx. |
| Eliminated use of sub-modules. |
| - Add support for the IAR toolchain for the limited case of the ARMv7-M |
| architecture and the STM32 chip. From Aleksandr Vyhovanec. |
| - make export: Pass top-level make to the script to allow -j greater |
| than 1. From David Sidrane. |
| - fs/Kconfig: Allow CONFIG_FS_WRITABLE to be manually selectable. This |
| is needed when there are no writable file systems, but write support |
| is still needed in BCH or FTL. |
| - arch/*/Makefile: Add definitions that can be overrided to use GCC |
| instead of LD in the final link. From Paul Alexander Patience . |
| |
| * Applications: apps/netutils: |
| |
| - apps/netutils/esp8266: ESP8266 driver application. From Pierre-noel |
| Bouteville. |
| |
| * Applications: apps/examples: |
| |
| - apps/examples/alarm: Add a simple test of the ALARM iotcl calls of |
| the RTC driver. |
| - apps/examples/nximage: Add a configuration option to select |
| greyscale. |
| |
| * Platforms: apps/platform: |
| |
| - apps/platform/nucleo-144: Add platform files for NUCLEO-144 |
| (NUCLEO-F746ZG). From Mark Olsson. |
| - apps/examples/media: You can now override the default device driver |
| path by providing an alternal path on the command line. From |
| Sébastien Lorquet. |
| |
| Works-In-Progress: |
| |
| * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were |
| introduced in NuttX-7.15. Work has continued on this effort on |
| forks from the main repositories, albeit with many interruptions. |
| The completion of this wireless feature will postponed until at |
| least NuttX-7.17. |
| |
| * i.MX6 SMP. Partially functional, but there is more that still |
| needs to be done. |
| |
| Bugfixes. Only the most critical bugfixes are listed here (see the |
| ChangeLog for the complete list of bugfixes and for additional, more |
| detailed bugfix information): |
| |
| * Core OS: |
| |
| - Various places: Search for places where a stray semicolon following |
| an if condition cause the if body to be executed unconditionally. |
| Fixes in all SAM DMA logic, unionfs, OS signalling logic, and others. |
| - enter/leave_critical_section() may attempt to access task lists |
| before they have been initialized in the SMP configuration. |
| |
| * File System/Block Drivers: |
| |
| - SMART MTD: Return code of smart_scan not checked, can cause success |
| result in failure case, leading to 'dev' pointer being invalid. From |
| Dave (ziggurat29) |
| - mount: Fix a backward debug assertion. Noted by David Sidrane. |
| |
| * Common Drivers: |
| |
| - NRF24L01: Fix backward calculation of relative frequency. Noted by |
| Henry Zhang. |
| - PCA9555 I/O expander: Fix an error in the PCA9555 driver: Under |
| certain error conditions, interrupts were not being re-enabled. |
| Sebastien Lorquet. |
| - ADS1255: Must not do SPI access from interrupt handler. Use the |
| worker thread instead. Must also lock the SPI bus before using it. |
| - Several SPI-based drivers modified. All drivers that use SPI must |
| call SPI_LOCK and SPI_UNLOCK. This is not optional. |
| - MS583730: Fix a bug in crc computation for ms583730. Implement |
| POSIX read. |
| |
| * Atmel SAMV7: |
| |
| - Fix typo in MATRIX register definitions. From Stefan Kolb. |
| - SAMV7 Tickless Mode: This is a fix to a problem in the handling of |
| the oneshot timer. Due to a wrong assumption concerning the behavior |
| directly after the start of the timer/counter the function |
| sam_oneshot_cancel(â¦) calculates the wrong remaining time. The code |
| assumes that the counter register is zero directly after the start |
| of the timer, but this is not true. To start the time/counter a |
| software trigger is invoked, this trigger starts the timer/count and |
| sets the counter register to zero, but the reset of the counter |
| register is not performed instantly. According to the datasheet: |
| "The counter can be reset by a trigger. In this case, the counter |
| value passes to zero on the next valid edge of the selected clock." |
| Thus the counter is set to zero between 0 and USEC_PER_TICK |
| microseconds after the clock was started. |
| In my fix I use the freerun count value to determine if at least one |
| tick passed since the start of the timer and thus if the value of |
| the oneshot counter is correct. I also tried to use the function |
| up_timer_gettime(â¦) to achieve this but, at least if compiled with |
| no optimization the problem vanishes without using the value of the |
| function, the function call takes too long. |
| Another problem treated in the fix is that if the oneshot timer/counter |
| is canceled, we only know the remaining time with a precision of |
| USEC_PER_TICK microseconds. This means the calculated remaining time |
| is between 0 and USEC_PER_TICK microseconds too long. To fix this I |
| subtract one tick if the calculated remaining time is greater than |
| one tick and otherwise set the remaining time to zero. By doing so |
| the measured times are much more precise as without it. From Stefan |
| Kolb. |
| |
| * Atmel SAMA5: |
| |
| - SAMA5: Stefan Kolb's change to the SAMV7 Oneshot Timer should also |
| be applied to the SAMA5 oneshot time since the drivers are identical. |
| |
| * Atmel SAM3/4: |
| |
| - SAM3/4: Stefan Kolb's change to the SAMV7 Oneshot Timer should also |
| be applied to the SAM3/4 oneshot time since the drivers are identical. |
| |
| * Atmel SAMV7 Drivers: |
| |
| - SAMV7 TWIHS (as well as SAM3/4 and SAMA5: Ensure that the TWIHS |
| (i2c) hw get's its clock set when the sequence of |
| sam_i2cbus_initialize(), sam_i2cbus_uninitialize(), then |
| sam_i2cbus_initialize() or twi_reset() is called. I found this a |
| while back in the stm32 family, so there may be more arch-es with |
| this sort of bug. I suppose any driver that has the notion of "do |
| not set the freq if it is already set" could be suspect. From David |
| Sidrane. |
| - USBHS Device: Remove disabling of whole USB on suspend of USBHS. |
| This fix removes the disabling of the whole USB peripheral on |
| suspend interrupt. Its enough to freeze the clock instead. When |
| disabling the whole peripheral, the next wakeup-interrupt comes up |
| with an disabled clocking. The unfreeze clock has no effect, because |
| the master clock is disabled. This makes all registers, including |
| the IDR unwriteable and the IRQ falls in an endless loop blocking |
| the whole system. Furthermore the disabling of the peripheral clock |
| prevents hotplugging or reconnecting the USB. From Frank Benkert. |
| - MCAN: Fix missing unlock of device in MCAN mcan_txempty(). From |
| Frank Benkert. |
| |
| * STMicro STM32: |
| |
| - STM32 L4 Clocking: Problem with resetting backup domain clears |
| clocking options set up before in *rcc.c use INITS flag to avoid |
| magic reg value to detect power up reset state of RTC correct a |
| problem clearing interrupt flags (they weren't) which prevented an |
| alarm from ever being used more than once per reset cycle. From |
| Dave (ziggurat29) |
| |
| * STMicro STM32 Drivers: |
| |
| - STM32L4 SPI: That STM32Lr SPI driver is quite different. They now |
| handle frames of arbitrary size between 4 and 16 bits. It was broken |
| before a new bit has to be set (RX fifo threshold) to handle <= 8-bit |
| transactions. If not set, the default is 16-bit packed >=8-bit |
| frames and the RXNE bit is never set (it is set when 16-bits are |
| received). weird things as always. This also add 8-bit access |
| routines to the data register, because a 16-bit access to the data |
| register when the frame size is below 9 bits is interpreted as a |
| packed dual frame exchange. Sebastien Lorquet. |
| - STM32: Correct some bad commits that broke the LTDC display example. |
| From Marco Krahl. |
| - STM32 F4 RTC: Fix logic in F4 RTCC driver that prevent ALARM |
| interrupt. From Neil Hancock. |
| - STM32 F1 ADC: Fix STM32 ValueLine ADC IRQ number selection. From |
| David Sidrane. |
| |
| * STMicro STM32 Boards: |
| |
| - STM32F429I Discovery: Correct some bad commits that broke the LTDC |
| display example. From Marco Krahl. |
| |
| * TI Tiva: |
| |
| - GPIO Interrupts: Fix a bug of GPIO falling-edge interrupt for tiva. |
| From Young. |
| |
| * C Library: |
| |
| - math: Add a NAN test on 'x' in asin function of lib_asin.c. Suggested |
| by Pierre-noel Bouteville. |
| |
| * Build/Configuration System: |
| |
| - Several Makefiles: Add .PHONY definitions to prevent 'clean up to date' |
| message weirdness when 'make clean' is done with no .config or |
| Make.defs file. |
