The change log associated with the release is available here. Unreleased changes after this release are available in SVN. These unreleased changes are listed here.
- This release includes several new features in various states of integration and maturity: + The version number of this release was bumped from 5.19 to 6.0. + A change in the major revision number is used to reflect an incompatibility with previous versions. + In this release, the NuttX core OS functionality has been separated from NuttX application-related functionality. + These are provided as separate tarballs:
nuttx-6.0.tar.gz, andapps-6.0.tar.gz+ The purpose of this separation is both to better organize and modularize the NuttX source tree, + but also to provide better support for incorporation of end-user applications with Nuttx. +
++ The incompatibily results from the changes to the board configuration logic needed to supported the separable application. + The major changes to the configuration include: +
+CONFIG_APPS_DIR - This should not, typically be set.
+ The default is ../apps.
+ This should only be set if you have a custom, product-specific application directory in some different location.
apps/ directory appears in this port.
- This apps/ directory provides a mechanism for applications using NuttX to have a highly customizable initialization process.
- It supports a set of end-user applications than can be executed
- (1) standalone so you can have a fully customizable application startup, or
- (2) on top of NSH.
- Think of it this way:
- In a buckled-up embedded application, your end-user programs will probably have their own dedicated start-up logic.
- But, during development, you might want to have you applications available and executable from the NSH command line.
- This apps/ add-on (and NSH hooks) was contributed by Uros Platise to accomplish just that.
- /etc/init.d/rcS File.
- NSH was also extended to support application specific ROMFS /etc/init.d/rcS start-up scripts.
- This feature, as well, as all of the above-mentioned apps/ directory support was contributed by Uros Platise
- waitpid().
- New waitpid() system interface.
- appconfig - Each board configuration now requires a new file called appconfig.
+ As its name suggests, this file provides new configuration information needed by the logic in ../apps.
+ In addition to this major reorganization in the directory structure, this release also includes some important extensions to existing features and + some important bugfixes. + These include: +
+fopen() and STM32 GPIO configuration
+ + Please see the ChangeLog for details. +

- QEMU i486. + QEMU/Bifferboard i486. This port uses the QEMU i486 and the native Linux, Cywgin, MinGW the GCC toolchain under Linux or Cygwin. STATUS: - This port is code complete but not yet tested. Stayed tuned. + The basic port was code-complete in NuttX-5.19 and verifed in NuttX-6.0. + The port was verified using the OS and NuttShell (NSH) examples under QEMU. + The port is reported to be functional on the Bifferboard as well. + This is a great, stable starting point for anyone interest in fleshing out the x86 port! |
