    nuttx-6.1 Release Notes:

    - The 67th release of NuttX, Version 6.0, was made on March 21, 2011 and is available for download from the + The 68th release of NuttX, Version 6.1, was made on April 10, 2011 and is available for download from the SourceForge website. 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.

    - 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, and
      • -
    • apps-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. -
      • -
    • 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: + The 6.0 release introduced a detach-able application environment to build applications outside of the NuttX source tree. + The primary purpose of this release is to correct numerous build problems introduced by that architectural change:

    • - The SLIP driver was been well debugged and significantly re-designed. - Now you can have an Ethernet connection to you board even if you have no Ethernet hardware. - How cool is that? + In many newer environments, NuttX produced strange Makefile errors but built correctly in older environments. + A fix provided by Rafael Norinha was incorporated and is reported to fix those build problems.
    • - The QEMU i486 port is now functional. - It has also been reported to work on the Bifferboard. + The apps/ directory build system would not handle Windows-native toolchains due to obscure path formatting issues.
    • - And extensions to the uIP driver interface, and + And other problems as detailed in the change log.
      • -
    • - Bug fixes to fopen() and STM32 GPIO configuration -
      • -
    +

    - Please see the ChangeLog for details. + Many additional changes were made in the 6.1 release for another major architectural change: + NuttX will now build as a seperately linked micro-kernel. + In this build option the RTOS builds as a kernel, applications build separtate and interface with kernel via system calls. + Applications run in user mode and kernel logic users in kernel-mode. + This provides a secure environment for NuttX. + This feature is fully coded in NuttX-6.1, but has not been tested due to higher priority tasks that have arisen. +

    +

    + Related to this change, support for the Cortex-M3 memory protection unit (MPU) has been integrated with the NuttX kernel build to provide an even higher level of security. +

    +

    + NOTE: This kernel build is an option; the default build configuration is still the standard, flat, unsecured RTOS as in previous releases. +

    +

+
+  Where flash_utility is one of:

+    crt_emu_cm3_nxp (for LPC17xx parts)
+    crt_emu_a7_nxp (for LPC21/22/23/24 parts)

+    -wire=winusb (for LPC-Link on Windows XP)
+    -wire=hid (for LPC-Link on Windows Vista/ Windows 7)
+
+  target is the target chip name. For example LPC1343, LPC1114/301, LPC1768 etc.
+
+  filename is the file to flash program. It may be an executable (axf) or a binary
+  (bin) file. If using a binary file, the base_address must be specified.
+
+  base_address is the base load address when flash programming a binary file. It
+  should be specified as a hex value with a leading 0x.
+
+  Note:
+  - flash-load will leave the processor in a stopped state
+  - flash-load-exec will start execution of application as soon as download has
+    completed.
+
+  Examples
+    To load the executable file app.axf and start it executing on an LPC1758
+	target using Red Probe, use the following command line:
+
+      crt_emu_cm3_nxp -pLPC1758 -flash-load-exec=app.axf
+
+    To load the binary file binary.bin to address 0x1000 to an LPC1343 target
+	using LPC-Link on Windows XP, use the following command line:
+
+      crt_emu_lpc11_13_nxp -wire=hid -pLPC1343 -flash-load=binary.bin -load-base=0x1000
