The change log associated with the release is available here. Unreleased changes after this release are available in CVS. These unreleased changes are listed here.
- This release includes a combination of some new features as well as several bugfixes. - New features include: + This is primarily a bugfix release and includes some important corrections to the code:
+ Plus less critical bugfixes as detailed in the ChangeLog. New features + include: +
CONFIG_APP_DIR.
- Generalized the way in which applications are built and linked with NuttX.
- The new configuration CONFIG_APP_DIR replaces CONFIG_EXAMPLE.
- CONFIG_EXAMPLE used to identify the sub-directory within the NuttX examples/ directory that held the example application to be built.
- That made it awkward to configure to build an application that resided outside of the NuttX examples/ directory.
- CONFIG_APP_DIR is more general;
- it can be used to refer to any directory containing the application to be built.
-
- For people who have their own configurations and/or Makefiles, you will need to make a couple of changes:
-
-
- CONFIG_EXAMPLE=foobar with CONFIG_APP_DIR=examples/foobar in all of the configuration files.
- examples/$(CONFIG_EXAMPLE) with $(CONFIG_APP_DIR)
- lib$(CONFIG_EXAMPLE)$(LIBEXT) with libapp$(LIBEXT) in your Makefiles.
- CONFIG_EXAMPLE.

This logic is only in place in - the arch/arm/src/Makefile for now. - * arch/arm/src/lpc17xx/lpc17_internal.h - Add missing parentheses in - macros definitions (patch submitted by Tiago Maluta). - * Documents/NuttxPortingGuide.html, configs/README.txt, etc. - - Replaced CONFIG_EXAMPLE with CONFIG_APP_DIR (see documents for - desciption). This allows NuttX application code to be built - outside of the examples/ directory. - - For people who have their own configurations and/or Makefiles, - you will need to make a couple of changes: - - - Replace all occurrences of CONFIG_EXAMPLE=foobar with - CONFIG_APP_DIR=examples/foobar in all of the configuration - files. - - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with - $(CONFIG_APP_DIR) - - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) - with libapp$(LIBEXT) in your Makefiles. - - Check any other occurrences of CONFIG_EXAMPLE. - - * arch/arm/src/lpc313x/lpc313x_spi.c - Fix compilation error when - when CONFIG_DEBUG is enabled. - * arch/arm/src/lm3s and arch/arm/include/lm3s - Support for the - lm3s8962 contributed by Larry Arnold. - * configs/lm328962-ek - Support for the TI/Stellaris EKC-LM3S8962 - board (also contributed by Larry Arnold). - * arch/arm/src/lpc313x/lpc313x_boot.c - The call to lpc313x_boardinitialized() - should not be conditioned on CONFIG_ARCH_LEDs being defined! - * arch/arm/src/lpc313x/ - APB0 and APB1 cannot lie in different - sections; they are too close together. - * arch/arm/src/lpc313x/lpc13x_boot.c - Resetting all of the clocking - had a side effect of wiping out the first 6 words of memory where the - interrupt vectors are located (and also not resetting the fractional - dividers). This is not usually noticeable because the IRQ vectors - are after this point, but really causes problems if you want to handle - data and prefectch aborts which are within this zeroed region. + * configs/ea3131/src/up_fillpage.c - Added new configuration item + CONFIG_PAGING_BINPATH.
