zephyrproject-rtos/zephyr zephyr-v1.5.0 on GitHub

The Zephyr Engineering team is glad to announce the release of Zephyr
Kernel 1.5.0. This is the first release to follow the 3-month release
cadence. This release includes numerous fixes and support for major
features. Additional changes include support for new drivers, sensors,
and boards.

Major enhancements included with the release:

TCP Support
Integration of the Paho MQTT Library support with QoS
Flash Filesystem Support
Integration of the mbedTLS library for encryption
Improved BR/EDR support (for L2CAP, in particular).
Support for the Altera Nios II/f soft CPU architecture

A detailed list of changes since v1.4.0 by component follows:

Kernel

Added nano_fifo_put_list() APIs, which allows queuing a list of
elements on a nanokernel FIFO.
Removed unused memory pool structure field.
Enhanced memory pool code.

Architectures

ARM: Updated to include floating point registers.

Altera Nios II/f soft CPU architecture support

:   -   Internal Interrupt Controller
    -   Avalon Timer
    -   Avalon JTAG UART (polling mode) as default for
        qemu-system-nios2, and 16550 UART as default for
        Altera MAX10.

Boards

Added Nios II QEMU board.
Added configuration for Altera MAX10 FPGA.

Drivers and Sensors

Sensors: Added driver for I2C HMC5883L magnetometer.
Sensors: Added driver for I2C TMP112 temperature sensor.
Sensors: Added driver for MAX44009 light sensor.
Sensors: Added driver for LPS25HB.
HAL: Updated QMSI drivers to 1.1
Added DMA QMSI shim driver.
Added Quark SE USB device controller driver.
Added suspend/resume to QMSI drivers.
Added Guard for critical sections of the QMSI drivers.
Added Zephyr File System API.
Added driver for ENC28J60 Ethernet SPI module.

Networking

TCP Support
Connection handling fixes in IP stack.
Allow sending zero length user data IP packet.

Network Buffers

New net_buf_simple API for light-weight on-stack (or static)
buffers where a net_buf (and its associated pool) is overkill. The
net_buf API now uses as an internal implementation
detail net_buf_simple.
Add support for network buffer fragmentation.
Add more net_buf big endian helpers.

Bluetooth

Multiple fixes & improvements to the nble driver.
New API for dealing with Out of Band data (like the local address).
Various smaller fixes & improvements in many places.

Build and Infrastructure

Added “qemugdb” target to start a local GDB on port 1234.
Added script to filter known issues in the build output.
Sanity: Added “-R” option to build all test with assertions.

Libraries

File system: Imported Open Source FAT FS 0.12a code.
Encryption: Imported mbedTLS library.
Encryption: Updated tinycrypt library to 2.0.

Documentation

Fixed all the documentations warnings during build.
Fixed several typos, trademarks and grammar.
Moved all the boards documentation to the wiki.
Moved Code Contribution documentation to the wiki.
Added package “ncurses” to the list of requirements.
Updated Mac OS X instructions.

Test and Samples

Samples: Replaced old debug macro to use new SYS_LOG macro.
Added TMP112 sensor application.
Added Quark SE power management sample application.
Added DMA memory to memory transfer sample.
Added sample for MAX44009 light sensor.
Added MQTT publisher and subscriber samples.
Added mbedTLS sample client.
