nuttx-5.5 Release Notes:

The change log associated with the release is available here. Unreleased changes after this release are available in CVS. These unreleased changes are listed here.
- This release includes one new, important extension to the - NX graphics system: + This relese includes one new port, some new drivers and some important bugfixes:
- NX was develop a couple years back on hardware that supported only framebuffer - devices, that is, video hardware with video memory directly converts the memroy - content to video. However, most MCUs that NuttX focuses on do not support such - video memory; rather, that typically only support LCDs via parallel or serial - interfaces. +
+ NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit. + At present, that port includes an OS test configuration and a NuttShell + (NSH) configuration with telnet support.
- This release of NuttX extends NX so that now renders directly to the LCD device - via its serial or parallel interface. No in-memory copy of the screen memory - need be maintained so this solution should also work in MCUs with very limited - SRAM. -
+ MMC/SD and Networking support are provided but not thoroughly verified + in this release: Current development efforts are focused on porting the + NuttX window system (NX) to work with the Evaluation Kits OLED display. ++ A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is + available in the source tree (but has not yet been fully verified because + I haven't properly connected it to hardware yet). +
+ The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and + some new networking configurations were added. The ENC28J60 has not + been tested on the STR-P711, however, because of hardware issues (I don't + think the USB powered board provides enough power for the ENC28J60 and + I don't have the right wall wart yet). +
+ Along the way, external interrupt support (XTI) was added to the STMicro + STR-P711 port and some important bugs were fixed in the STR-P711 SPI + driver. +
+ Corrected an important UDP reference counting error. It was not a serious + error, but it trigger an assertion was IS a serious error. +
- This initial release of this feature includes the verified NX extensions plus - a driver for the HX8347, 16-bit parallel LCD. This LCD supports 16-bit RGB - (5:6:5). -
