Note +that release consists of two tarballs: nuttx-6.16.tar.gz and +apps-6.16.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +New features and extended functionality: + + * ARMv7M Support: Includes new, streamlined Cortex-M exception + handling provided by Mike Smith. Context switching support for the + Cortex-M4 FPU registers is now provided (in both "lazy" and "non-lazy" + modes) + + * General Drivers: Added a generic "upper half" Quadrature Encoder driver. + The USB CDC/ACM serial driver can now be dynamically connnected or + disconnected from the host (programmatically or using NSH commands). + + * STM32 Drivers: Added a "lower half" Quadrature Encoder driver. + Verified the STM32 F4 DMA driver; Added F4 DMA support to the existing + STM32 SDIO driver. + + * STM32 Board Support. Added support for the STM32 F2 family and + for the STM3220G-EVAL board (contributed by Gary Teravskis). + Support is now included for C++ static constructors (verified using + the Atollic toolchain). Added support for the SRAM available on the + STM3240G-EVAL board. + + * PIC32 Drivers. PIC32MX USB (device) driver is now functional. + The PIC32MX Ethernet driver not yet fully verified (and an + unverified SPI driver is also available). + + * Networking. Added a lower-level, thread-independent socket layer. + Parts of this layer were created in 6.15 to support the FTPD + controlling terminal; this support has been extended in order + to support an NFS file system (not yet released). + + * NuttShell (NSH). NSH will now support a USB serial connection for + the console (such as CDC/ACM). This is useful in environments + where there is no physical serial port on the board. + + * Build System. Reorgnaization of networking header files. + +Critical Bugfixes. The following bug fixes are considered critical: + + * Networking: Fixed a "leak" in the TCP/IP read-ahead buffering logic. + Corrected an error in TCP/IP sequence numbering/ACK logic which + occurred when read-ahead buffering memory is exhausted. + + * STM32 Drivers: Fixed an buffer sizing error in the STM32 Ethernet + driver. + +Additional Bugfixes: Other important bug fixes are listed below. See +the ChangeLog of a complete, detailed list of bug fixes. + + * Networking: Corrected recv()/recvfrom() return value. Added logic to + monitor for loss of connection after a new connection has been + established via accept() (Contributed by Max Nekludov). Add + logic to select() to correctly handle POLLHUP (Contributed by Max + Nekludov) + +Additional bugfixes, name changes, and other differences as detailed in the +ChangeLog. + |
