boolean must replaced with the
- standard type bool.
- The type definition for bool is in stdbool.h.
-
-
-- This change in typing caused small changes to many, many files. - The changes was verified that all configurations in the release still build correctly - (other than the SDCC-based configurations). - Regression testing was performed on a few configurations, but it is possible that minor build - issues still exist (if you encounter any, please let me know and I will - help you to fix them). -
-- In the course of the regression testing, several important bugs unrelated - to the type changes were found and corrected. - Two of these are critical bugs: -
-
-
- Fixed an important error in the RX FIFO handling logic of the LM3S6918 - Ethernet driver. -
- Corrected the handling of TCP sequence numbers in the TCP stack. -
- And other less important bug fixes as detailed in the ChangeLog. -
-- The primary focus of this release was standards compatibility, but a few new - features were added including a (1) Flash Translation Layer (FTL) that will - support filesystems on a FLASH device and (2) partial ports for the STM32F107VC - and HCS12 M9S12NE64 MCUs. Those ports are very incomplete as of this writing. + A few additional features and bugfixes of a minor nature were also incorporated + as detailed in the ChangeLog.

+ NXP LPC3131. The basic port for the NXP LPC3131 on the Embedded Artists EA3131
+ development board was released in NuttX-5.1 with a GNU arm-elf or arm-eabi toolchain* under Linux or Cygwin.
+
+ + + +
+ STATUS: + The basic EA3131 port is complete in NuttX-5.1 but, unfortunately, has not yet been verfied. + That effort has stalled due to some tool-related issues. + Those tool issues have been resolved and I am confident that the verified basic EA3131 port will be + available in NuttX-5.2. The extended release will follow and should include SDIO-based SD card + support and device USB. + + |

+ + Atmel AT91SAM3U. + This port uses the Atmel SAM3U-EK + development board that features the AT91SAM3U4E MCU. + This port uses a GNU arm-elf or arm-eabi toolchain* under either Linux or Cygwin (with native Windows GNU + tools or Cygwin-based GNU tools). + +
+ STATUS: + The basic SAM3U-EK port was released in NuttX version 5.1. The basic port includes boot-up + logic, interrupt driven serial console, and system timer interrupts. + That release passes the NuttX OS test and is proven to have a valid OS implementation. + A configuration to support the NuttShell is also included. + ++ Subsequent NuttX releases will extend this port and add support for SDIO-based SD cards and + USB device (and possible LCD support). + These extensions may or may not happen by the Nuttx 5.2 release as my plate is kind of full now. + ++ Development Environments: + 1) Linux with native Linux GNU toolchain, 2) Cygwin with Cygwin GNU toolchain, or 3) Cygwin + with Windows native toolchain (CodeSourcery or devkitARM). A DIY toolchain for Linux + or Cygwin is provided by the NuttX + buildroot + package. + + |

- * arch/hc: Adding framework to support m68hc11/12
- * configs/demo9s12ne64: Configuration to support Freescale DEMO9S12NE64
- development board (MC9S12NE64 m68hcs12 processor).
- * drivers/mtd/ftl.c - A FLASH translation layer (FTL) has been implemented.
- This layer will convert a FLASH MTD interface into a block driver that
- can be used with any file system. Good performance of this layer will
- depend upon functioning write buffer support!
- NOTE: FTL support is untested as of the initial check-in.
- * Numerous minor changes for m68hc12 to eliminate compilation errors and
- warnings due to the fact that it uses 16-bit integer types and for casts
- between uint32 (32-bits) and an mc68hc12 pointer (16-bits).
- * sys/types: Size of off_t and blkcnt_t should not depend on size of
- int in the architecture; Removed non-standard type STATUS
- * include/ - Added header files stdint.h, stdbool.h, cxx/cstdint, and
- cxx/cstdbool
- * Changed ALL references to non-standard fixed-size types (like uint32,
- ubyte, etc.) to standard types (like uint32_t, uint8_t, etc.) from
- stdint.h. Use type bool and {true, false} from stdbool. This effected
- most of the files in the system! Almost all configurations have been
- re-built and many have been re-verified in order to get confidence in
- these changes.
- * graphics/ and examples/nx - Fix numerous build errors that have been
- introduced lately. NXGL has suffered some bit-rot from not being used
- in some of the most recent ports.
- * The misc/pascal NuttX add-on package has been updated to use the new
- standard types from stdint.h and stdbool.h and re-integrated with NuttX.
- The released pascal-2.0 will be the first version that contains the
- compatible changes.
- * arch/arm/src/lm3s/lm3s_ethernet.c - Fixed an important bug in the LM3S
- ethernet driver: If full packet is received, the packet-too-big check
- will fail because it needs to subtract 6 from the packet size (to
- account for the 2-byte packet length and the 4-byte packet FCS in the
- FIFO).
- * net/accept.c - Fixed a bad assertion (only happens when debug is enabled).
- * net/send.c net/uip/uip_tcpseqno.c - Fixed a critical error in the TCP/IP
- logic. The NuttX port of uIP imcludes logic to send data ahead without
- waiting for ACKs from the recipient; this greatly improves throughput.
- However, the packet sequence number was not being updated correctly and,
- as a result, packets were not be ACKed by the recipient and transfers
- would sometimes stall. This is a very important bug fix (in fact, I
- don't understand how TCP/IP worked at all without this fix???)
- * include/nuttx/arch.h and arch/*/common/up_udelay.c - Change argument
- of up_udelay() to type useconds_t to avoid warnings when sizeof(int)
- is 16-bits.
- * drivers/mmcsd/* - Add casts in contant expressions to avoid warnings
- when sizeof(int) is 16-bits.
+ * arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework

+ * Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131
+ (LPC3131) is code complete and waiting for me to get hardware in
+ hand.
+ * arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek -
+ Added the basic framework needed to begin a port for the SAM3U-EK
+ development board.
+ * confgs/ea3131/tools: Added a tool to create a image suitable for
+ use with the LPC313x bootloader.
+ * configs/sam3u-3k/ostest - Completed verification of the basic NuttX
+ OS test for the SAM3U.
+ * arch/arm/src/common/up_createstack - stack was always been cleared
+ when it was allocated. This is a good feature for monitoring the
+ stack during debug, but really hurts thread start-up performance.
+ Clearing is now done if CONFIG_DEBUG=y only. Changes was only made
+ for arm, but really should be made for all architectures.
+ * configs/sam3u/nsh - Added NSH configuration for SAM3U
