Outbound traffic to enter and leave multicast groups has been verified, but full verification will require a switch capable of multicast. Issues associated with the receipt of multicast packets are likely. + +nuttx-5.9 +^^^^^^^^^ + +This is the 56th release of NuttX. This release is difficult to categorize; +NuttX-5.9 was really released because there were too many changes accumulating +in CVS -- a few important, some unfinished implementations, and a couple of +important bugfixes. + + * By far biggest change in this release is the complete implementation + of on-demand paging support. This feature will allow you to execute large + programs on a mass storage device (such as SPI FLASH) in a small RAM. + All of the core on-demand paging logic was completed (see + http://www.nuttx.org/NuttXDemandPaging.html) and support was implemented + for the ARM-9 family. A test configuration is in place for the NXP + LPC3131. It has been verified that this new logic does not interfere + with normal fixed-page ARM9 operation, but otherwise this new on-demand + paging feature is untested. + * Add support for the CodeSourcery toolchain to the Olimex-lpc2378 port + and for the Neuros OSD port. + * The Neuros OSD port has been updated to work with the production v1.0 + OSD (previously it only worked with the development board). + * And some miscellaneous feature enhancements as detailed in the ChangeLog. + +This includes several important bugfixes: + + * NXP LPC17xx - Fixed a critical bug in the GPIO configuratino logic: + When attempting to set no pull-up or pull-down (floating), it would, + instead, select pull-down. + * TI/Luminary LM3Sxxxx - Fixed (1) a logic error in an address table + lookup, (2) GPIO port encoding the limited support to only 8 GPIO + ports. + * Corrected the lease time in the DHCPC implementation: It was not in + host byte order. + * And several other less important bugs as documented in the ChangeLog: + Warnings, cornercase compilation problems, etc. + |
