Zephyr Kernel 1.6.0
|
|
####################
|
|
|
|
We are pleased to announce the release of Zephyr kernel version 1.6.0. This
|
|
release introduces the unified Kernel replacing the separate nano- and
|
|
micro-kernels and simplifying the overall Zephyr architecture and programming
|
|
interfaces.
|
|
Support for the ARM Cortex-M0/M0+ family was added and board support for
|
|
Cortex-M was expanded.
|
|
Additionally, this release adds many improvements for documentation, build
|
|
infrastructure, and testing.
|
|
|
|
Major enhancements included with the release:
|
|
|
|
* Introduced the Unified Kernel; the nano and micro kernel were removed.
|
|
* The legacy API is still supported but deprecated.
|
|
* Legacy tests and samples were moved to tests/legacy and samples/legacy.
|
|
* Unified kernel documentation was added and legacy nanokernel/microkernel
|
|
documentation was removed.
|
|
* Added support for several ARM Cortex-M boards
|
|
* Added support for USB mass storage and access to the filesystem.
|
|
* Added native Bluetooth Controller support. Currently nRF51 & nRF52 are supported.
|
|
|
|
A detailed list of changes since v1.5.0 by component follows:
