+NuttX-7.15 Release Notes
+------------------------
+
+The 115th release of NuttX, Version 7.15, was made on March 27, 2016,
+and is available for download from the Bitbucket.org website.  Note
+that release consists of two tarballs:  nuttx-7.15.tar.gz and
+apps-7.15.tar.gz.  These are available from:
+
+    https://bitbucket.org/patacongo/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:
+
+      - Add a state variable that provides the current level of OS
+        initialization.  This is needed by some logic that may attempt to
+        run early in the start-up sequence but cannot run if a sufficient
+        level of initialization has not yet occurred.
+      - Spinlocks:  Add interface definitions for to support spinlocks as
+        needed for multi-CPU configurations.
+      - SMP support.  Support for Symmetric Multi-Processing (SMP) added.
+        This affects many internal data structures, spinlock extensions
+        and renaming of interrupt enable/disable interfaces, new platform
+        interfaces to support CPU initialization and inter-actions, and
+        new application interfaces to manage CPU affinity.  The changes
+        are too extensive to summarize here; see the SMP Wiki page at
+        http://www.nuttx.org/doku.php?id=wiki:nxinternal:smp.  The
+        new platform interfaces are also described in the NuttX porting
+        guide: http://www.nuttx.org/doku.php?id=documentation:portingguide.
+        Only partially verified; awaiting hardware for the complete
+        verification.
+      - TLS:  Basic definitions needed to support thread local storage
+        (TLS).  TLS is not used anywhere yet (and may not be used in the
+        near future either).
+      - Performance Monitoring:  Add a configuration option to buffer
+        RTOS instrumentation data in an in-memory buffer.
+      - boardctl():  Add boardctl() support that will permit applications
+        to control USB devices.
+
+    * File Systems/Block Drivers:
+
+      - procfs:  Add /proc/kmm entry that shows that state of the kernel
+        heap.  Only useful in PROTECTED and KERNEL build modes where there
+        is a kernel heap.
+      - procfs:  Add support for showing CPU in the tast status if SMP is
+        enabled.
+
+    * Networking:
+
+      - ARP: Add support for IOCTL commands to manage the ARP table.
+      - IEEE 802.15.4 and 6LowPAN:  There are some radio drivers and a
+        directory structure is in place.  However, most of this
+        development is occurring on a fork and is not yet available in the
+        NuttX repositories.  Hopefully in NuttX-7.16.
+
+    * Common Device Drivers:
+
+      - ADS1242:  Driver for the  24-Bit Differential Input ADC ADS1242 that
+        communicates via SPI with a MCU. Reading the ADC conversion result
+        as well as configuring the ADC, setting the input channel, etc. is
+        implemented via ioctl calls.  However, it does not yet implement
+        the standard ADC interface.  From Alexander Entinger.
+      - U-Blox Modem:  Add an upper half driver for the U-Blox Modem.  From
+        Vladimir Komendantskiy. 
+      - I2C: Add an I2C, "upper half", character drivers to support raw I2C
+        data transfers for test applications.
+      - RGB LED: Add a driver to manage a RGB LED via PWM.  From Alan
+        Carvalho de Assis.
+      - Performance Monitoring:  Add a character driver that will allow an
+        application to read buffered scheduler instrumentation data.
+
+    * Simulation Platform:
+
+      - SMP:  Add multi-CPU support to the simulation to support SMP
+        investigation.  There are issues with the simulation and it is less
+        than perfect but sufficient for some very preliminary testing of
+        the core SMP feature.
+
+    * ARMv7-A, ARMv7-R, and ARMv7-M:
+
+      - ARMv7-A, ARMv7-R, and ARMv7-M: Add test-and-set logic and
+        definitions needed to supports spinlocks.
+      - ARMv7-A: Added MPCOre Generic Interrupt Controller (GICv2) and
+        Global Timer support
+      - ARMv7-A: Now includes in MCU-specific hooks needed for SMP support.
+
+    * Atmel SAMV7 Drivers:
+
+      - HSMSI: HSMCI driver can now be configured to handle unaligned data
+        buffers.
+
+    * NXP Freescale LPC11xx/17xx/43xx and LPC2378 Drivers:
+
+      - I2C: Backported the LPC43XX I2C driver, replacing the LPC11XX,
+        LPC17XX, and LPC2378 I2C drivers.  This gives us the I2C_TRANSFER
+        method in all I2C drivers.
+
+    * NXP Freescale LPC17xx Boards:
+
+      - Support for the u-blox GSM and GPS module evaluation board with
+        NXP LPCExpresso LPC1768.  The GSM module is one of LISA-C200,
+        LISA-U200 or SARA-G350. The GPS module is one of MAX-M7 or
+        MAX-M8.  From Vladimir Komendantskiy.
+
+    * NXP Freescale i.MX6:
+
+      - Basic support is in place for the i.MX6 Quad/Dual MCUs.
+        Verification is, however, waiting for the receipt of hardware.
+
+    * NXP Freescale i.MX6 Boards:
+
+      - Sabre-6Quad:  Basic support for the NXP/Freescale Sabre 6Quad
+        board is in place but waiting for hardware for verification.
+
+    * STMicro STM32:
+
+      - STM32F46xx:  Support for STM32F46xx from Paul Alexander Patience
+      - STM32L4:  Add support for the STM32L4 family.  From Sebastien
+        Lorquet.
+
+    * STMicro STM32 Boards:
+
+      - STM32F4 Discovery: Add PWM support for the onboard RGB LED. From
+        Alan Carvalho de Assis.
+      - Nucleo-L476:  Add support for the Nucleo-L476 board.  From Sebastien
+        Lorquet.
+      - STM32L476VG Discovery: Add support for the STM32L476VG Discovery
+        board.  From Dave.
+
+    * Tools:
+
+      - tools/refesh.sh now has a --silent option so that it can be used in
+        batch modes without human input.
+
+    * Build System:
+
+      - Added a 'make olddefconfig' target that will refresh a .config file
+        without interaction.
+
+    * Applications: NSH
+
+      - 'arp':  Add an 'arp' command that will support access to the OS ARP
+        table.
+      - 'ps':  The 'ps' command will show CPU if SMP is enabled.
+
+    * Applications: apps/netutils:
+
+      - apps/netutils/chat: Chat logic contributed by Vladimir
+        Komendantskiy.
+      - apps/netutils/netlib:  Add utility functions to support accesses to
+        the ARP table.
+
+    * Applications: apps/examples:
+
+      - apps/examples/chat: Chat example contributed by Vladimir
+        Komendantskiy.
+      - apps/sysem/ubloxmodem:  Example to control the power
+        state of the modem in nsh.  From  Vladimir Komendantskiy.
+      - apps/examples/leds: An example to demonstrate use of LED driver.
+      - apps/examples/smp:  Add a test to verify SMP configurations.
+      - apps/examples/rgbled:  Example using the RGB LED driver to drive an
+        RGB LED via PWM.  From Alan Carvalho de Assis.
+      - apps/examples/ostest:  Add a test of TLS.
+      - apps/examples/sched_note:  Add a simple example to exercise the
+        scheduler instrumentation logic.
+
+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:
+
+      - Signals:  Move the list of signal actions from the TCB to the group
+        structure.  Signal handlers are not per thread but, rather, per task
+        group.  I know, I preferred it the other way too, but this is more
+        compliant with POSIX.
+      - Semaphores: Add an internal, non-standard interface to reset a
+        semaphore count.  This is sometimes needed by drivers in order to
+        recover from error conditions.  Were previously using sem_init()
+        which is both inappropriate and incorrect if the semaphore count is
+        negative.
+      - Low-Priority Work Queue:  Fix logic to find an IDLE worker thread;
+        the test for busy was backward.  From Linfei Chen.
+
+    * File System/Block Drivers:
+
+      - FAT:  Add an option to force all transfers to be performed
+        indirectly using the FAT file system's internal sector buffers.
+        This is a fix for the case where the user provided buffers are not
+        properly aligned for DMA (as with THTTPD).
+      - MTD:  Increase block size in mtd_geometry_s to 32-bits.
+
+    * Common Drivers:
+
+      - I2C:  Restructured the I2C interface as necessary to eliminate some
+        thread-safety issues inherent in the legacy I2C interface design.
+        This effects the interface definition, all I2C clients, and all low-
+        level I2C drivers.  I have used caution, but I still expect a change
+        of this magnitude to introduce some errors. Any bug reports of bug
+        fixes will be much appreciated.
+      - I2C_RESET:  Eliminate up_i2creset().  It should not be a global
+        function; Now it is an I2C interface method.
+      - PCA555:  Add logic to make the PCA555 driver thread safe.
+      - syslog: If syslog timestamping is enabled, don't try to get the time
+        if the timer hardware has not yet been initialized.
+      - AT24xx driver: Correct missing address calculation logic.  From Frank
+        Benkert.
+
+    * Networking:
+
+      - Networking drivers that support CONFIG_NET_NOINTS:  Fix a race
+        condition that can cause the TX poll timer to stop running.  From
+        Manuel Stuhn.
+      - Timer Poll:  Fix some logic when there are multiple network
+        interfaces.  In this case, TCP timeout events can really only being
+        processed when the poll from the correct device is received.
+
+    * Atmel SAMV7 Drivers:
+
+      - SAMV7 USB HS device:  The USB driver has had some issue that would
+        occasionally cause loss of packets.  Back last December, a fix was
+        put in for this but the fix apparently worsens the problem; now
+        causing hangs.  The basic problem is that the number of busy banks
+        (NBUSYBKS) status is not real time but is delayed.  This was fixed;
+        now when the DMA completes and NBUSYBKS > 0, the NBUSYBK is
+        interrupt is enabled and the operations are deferred until NBUSYBKS
+        is truly zero.
+
+    * Tools:
+
+      - tools/testbuild.sh:  .config files were not being updated because
+        (a) kconfig-conf was being called in the wrong directory and (b)
+        apps/Kconfig had not yet been created.  Now uses 'make
+        olddefconfig'.
+
+    * Applications: apps/system:
+
+      - apps/system/i2c:  The I2C tool now obeys it OS interfacing: it now
+        uses an I2C character driver to access the I2C bus.
+      - apps/system/cdcacm, usbmsc, and composite:  Use new boardctl()
+        instead of calling directly in the OS when possible.
+
+    * Applications: apps/netutils:
+
+      - apps/netutils/dhcpd: DHCPD no longer calls directly into the OS but
+        uses the new network IOCTL commands to modify the ARP table.
+
+    * Applications: apps/modbus:
+
+      - apps/modbus/nuttx/portserial.c:  Was not returning an error on
+        failure to open the device driver.  From Olololshka kokoko.
+
+    * Applications: apps/examples:

+      - apps/examples/usbserial, composite, usbterm:  Use new boardctl()
+        instead of calling directly in the OS when possible.  There are
+        still a few bad OS calls for USB device interfaces that do not yet
+        have boardctl() commands.
+
+    * Applications: apps/platform:
+
+      - Moved C++ initialization logic out of the RTOS and into the
+        application space, specifically to apps/platform/board, where it
+        belongs.
