| NuttX-6.19 |
| ---------- |
| |
| The 86th release of NuttX, Version 6.19, was made on June 15, 2012, |
| and is available for download from the SourceForge website. Note |
| that release consists of two tarballs: nuttx-6.19.tar.gz and |
| apps-6.19.tar.gz. Both may be needed (see the top-level nuttx/README.txt |
| file for build information). |
| |
| This release corresponds with SVN release number: r4847 |
| |
| This release features new support for a Network File System (NFS) client. |
| This feature allows a tiny, embedded MCU to mount a remote file system |
| exported by an NFS server and then to access the file system as it would |
| any local file system. Then the tiny MCU can effectively have terabytes |
| of storage! |
| |
| This might be useful for data collection, for MCU configuration information, |
| for software updates, for providing modular, loadable code modes, controlling |
| a "farm" of MCUs, ... there are many possibilities and opportunities for |
| innovation! |
| |
| The NuttShell (NSH) now supports the following command: |
| |
| nfsmount <server-address> <mount-point> <remote-path> |
| |
| That command will mount the remote NFS server directory <remote-path> at |
| <mount-point> on the target machine. <server-address> is the IP address of |
| the remote server. |
| |
| The NFS development was the graduation project of Jose Pablo Rojas V. who |
| is a student at the Instituto Tecnolรณgico de Costa Rica (ITCR, or TEC). |
| A lot of effort went into understanding what a tiny, embedded NFS client should |
| do and getting the target resource usage to a bare minimum. Only around a |
| kilobyte or so of memory is required to run the NFS client (and most of that |
| for I/O buffers). Jose Pablo has spent several months living with NFS and |
| should be congratulated. |
| |
| Additional new features and extended functionality: |
| |
| * Drivers: SSD1289 LCD driver, MIO283QT2 LCD driver |
| |
| * LM3S: Additional register definition header files (contributed by Max |
| Neklyudov). |
| |
| * STM32 Boards: The STM32F4Discovery will now support an SSD1289 LCD, |
| The STM3220G-EVAL board support is now equivalent to the STM3240G-EVAL |
| board support. |
| |
| * PIC32 Boards: The Mikroelektronika PIC32MX7 MMB board port is now |
| functional, very complete, and stable. |
| |
| * Graphics: The NxConsole will now take keyboard input from the NX graphics |
| subsystem. This means that if there are multiple NxConsole windows, only |
| the top instance that has focus will receive the keyboard input. |
| |
| * apps/: Add the capability to use an arbitrary USB device as the console |
| (not necessarily /dev/console). Additional enhancements for USB consoles. |
| Added the 'mv' command. |
| |
| Work in progress. This release includes some partially completed |
| work that is still not ready for prime time. |
| |
| * Automated Configuration. Automated configuration based on the |
| kconfig-frontends tool is being incorporated into the build |
| system. The configuration is still not complete enough for |
| general use in this release. |
| |
| * STM32 Drivers. Added files that will (eventually) hold an STM32 |
| OTG FS host driver. This is still a work in progress. |
| |
| Bugfixes (see the change log for details) : |
| |
| * General: sleep() and usleep() return values, sig_timedwait() errno setting |
| on timeout. |
| * Drivers: STMPE811 touchscreen driver, USB PLC2303, USB CDC/ACM |
| * STM32: Several USB device controller driver fixes, F4 interrupt priorities |
| (contributed by Mike Smith). |
| * Graphics: Keyboard input, fill trapezoid bug |
| |
| As well as other, less critical bugs (see the ChangeLog for details) |
