| NuttX-6.30 |
| ---------- |
| |
| The 97th release of NuttX, Version 6.30, was made on September 14, 2013, |
| and is available for download from the SourceForge website. Note |
| that release consists of two tarballs: nuttx-6.30.tar.gz and |
| apps-6.30.tar.gz. Both may be needed (see the top-level nuttx/README.txt |
| file for build information). |
| |
| Additional new features and extended functionality: |
| |
| * Common Drivers: |
| |
| - Extended TERMIOS support for serial and CDC/ACM drivers. From |
| Mike Smith, Andrew Tridgell and Lorenz Meier. |
| - Added option to disable serial port reordering. From Lorenz Meier. |
| - Several changes to the USB host control interface and extensions to |
| common USB host logic to handle host controllers with multiple |
| downstream ports in the root hub. |
| - USB device tracing: Extended decoding and stringifying of USB trace |
| output to include trace output from class drivers. |
| - USB host tracing: Added support for USB host tracing similar in |
| some ways to USB device tracing: Stringification is an inherent |
| part of the trace decoding (not an option). Only available in the |
| SAMA5 USB host drivers now. |
| |
| * Networking / Network Drivers |
| |
| - Support for the Microchip ENCX24J600 Ethernet driver from Max |
| Holtzberg |
| - CC3000 Networking. Initial support for the TI CC3000 network |
| module on the Freescale Freedom-KL25Z board from Alan Carvalho |
| de Assis. This is still a work in progress. |
| |
| * ARMv7-A, Cortex-A5 |
| |
| - Restructured some MMU-related logic and header files. |
| - Hooks added for Cortex-A8, but not yet used. |

| consistency. Change submitted by CCTSAO. |
| - apps/system/usbmonitor: The USB monitor has been extended so that |
| it can be used with USB device or host trace data. |
| |
| Efforts In Progress. The following are features that are partially |
| implemented but present in this release. They are not likely to be |
| completed soon. |
| |
| * CC3000 Networking |
| |
| - CC3000 Networking. Initial support for the TI CC3000 network |
| module on the Freescale Freedom-KL25Z board from Alan Carvalho |
| de Assis. This is still a work in progress. |
| |
| * kconfig-fronted Configuration: |
| |
| - Conversion of old configurations to use the kconfig-frontends |
| tool is an ongoing effort that will continue for some time. |
| At this time, only 46% of the configurations have been converted |
| to use the kconfig-frontends tools. |
| |
| Bugfixes (see the ChangeLog for details). Some of these are very important: |
| |
| * File Systems: |
| |
| - ROMFS: Fix an error where long (>15) file names were read |
| incorrectly from a ROMFS file system. From Mike Smith |
| - NXFFS: Clean up some compiler warnings. |
| |
| * Common Drivers |
| |
| - MMC/SD driver: Correction for a bad return value when multiple |
| block SDIO transfers are suppressed. By Andrew Tridgell. |
| - USB HID keyboard and mass storage host-side class drivers: Fix some |
| compilation errors and warnings when pre-allocated data structures |
| are used. |
| - USB device-side class drivers: Fix some compilations errors when |
| DUALSPEED (i.e., full- and high-sped) support is enabled. |
| - CDC/ACM and PL2303: Don't use max packetsize assigned to the endpoint |
| when allocating request buffers; The default value of the endpoint |
| max packetsize may be incorrect because the endpoint has not yet |
| been configured. Really only an issue for high-speed endpoints. |
| - USB Host Mast Storage Class: Fixed a problem that was causing some |
| devices to fail to initialize: If device is returning fatal transfer |
| errors while attempting to initialize, don't bother with the startup |
| retries; abort immediately so that the device will be reset and we |
| can try again with a better ready device. |
| - USB Host Mast Storage Class: Correct a reference counting error: |
| When an MSC device transfer fails while waiting for UnitTestReady, |
| the reference count on the class was not being decremented. The end |
| result is a memory leak as can be seen by the USB device numbers |
| incrementing: sda, sdb, sdc, ... |
| - USB Device CDC/ACM: Fix backward conditional compilation in the |
| CDC/ACM driver with regard to remote wakeup and self-powered |
| capabilities. From the PX4 team via Lorenz Meier, |
| |
| * Networking / Network Drivers |
| |
| - ARP IP harvesting: Correct backward condition in netmask task. |
| From Max Holtzberg. |
| - Network connection monitor: Fixes a race condition where a loss of |
| connection may not be detected when the connection is lost before it |
| has been accepted (from Max Holtzberg). |
| - TCP/IP Backlog: Fix a critical bug in the TCP/IP backlog |
| initialization: Only the first backlog buffer was getting added to |
| the free list. From Max Holtzberg. |
| - ENC28J60: Fixes and improvements back-ported from the ENCX24J600 |
| to the ENC28J60 by Max Holtzberg. |
| |
| * STM32 Drivers: |
| |
| - STM32 I2C fixes for the STM32 F3 family from John Wharington. |
| - STM32 I2C Correct an error that crept into the STM32 F1 I2C |
| driver with some recent changes. From Librae |
| - STM32 F4: Added some missing CONFIG_SERIAL_TERMIOS support; Fixed |
| some STM32 F4 Timer 8 pin configurations. From CCTSAO. |
| - STM32 SDIO: If CONFIG_SDIO_BLOCKSETUP defined, OS would crash. Now |
| Generate an error if CONFIG_SDIO_BLOCKSETUP is defined; that |
| option is not yet supported by the STM32 SDIO driver. From CCTSAO |
| - STM32 I2C Timers: Some CCER bit settings changed. Submitted by |
| CCCTSAO. |
| - STM32 CAN: Fix access to CAN filter registers. From the PX4 team |
| via Lorenz Meier. |
| - STM32 Kconfig: Fix STM32 UART7/8 Kconfig names and UART DMA. From |
| the PX4 team via Lorenz Meier. |
| |
| * LPC17xx Drivers |
| |
| - Fix #endif with missing #if in USB host header file. Reported |
| by Andrew Bradford, |
| |
| * SAM3/4 Boards: |
| |
| - Corrected DMA-related problems: Bad register definitions, parameters |
| reversed in a function call. |
| - Correct a race condition in the HSMCI driver when an interrupt |
| occurs before the wait for the interrupt begins. |
| - Peripheral clock setup: Correct a typo in a register name. |
| |
| * Atmel AT91 SAMA5D3 |
| |
| - Order of some operations changed in boot-up logic to defer |
| enabling of caching of memory regions until SDRAM is initialized. |
| - Correct handling of spurious interrupts. |
| |
| * Freescale KL25Z Drivers |
| |
| - KL25Z SPI: Correct typo in name of a function. From Alan Carvalho |
| de Assis. |
| |
| * Applications: |
| |
| - apps/examples/composite: Fix a typo that can cause a configuration |
| error. From CCTSAO. |
| - apps/examples/pwm: Clean-up some configuration confusion. |
| - apps/netutils/dhcpd/dhcpd.c: Fixed calculation of the next lease |
| address. From Paolo Messina. |
| - apps/examples/usbmsc: Don't try to control USB trace if we are |
| an NSH built-in task. In that case our attempts are inadequate |
| and only interfere with with other logic that is attempting to |
| to do the same thing (in NSH or in the USB monitor). |
| - apps/examples/usbmsc: IMPORTANT bug fix: Change how the msconn |
| works. Because of recent changes the msconn command was hanging. |
| This was because the USB MSC start-up logic creates a pthread; |
| Now waitpid() will wait until all members of the task group |
| exit. So NSH was hanging in waitpid when msconn started even |
| though msconn returned. The USB MSC logic really should not use |
| a pthread, but we are stuck with that for now. The work-around |
| is the msconn now daemonizes itself so that it so that the pthread |
| is created in a different task group. |
| - apps/nshlib: Fix NSH listing output for the case of a single file. |
| From the PX4 team; provided by Lorenz Meier. |
