Watch for announcement of the completed LPC1768 port expected in NuttX-5.8. + +nuttx-5.8 +^^^^^^^^^ + +This is the 55th release of NuttX. This includes several important bugfixes: + + * Corrects some interrupt vectoring for the TI/Stellarix LM3S port + * Correct initialization logic for NXP LPC17xxx NuttX ports: Power was + not being provided to the GPIO module! + * Corrected (but did not verify) implementation of the optional interrupt + stack feature (all Cortex M3 architectures). + * Correct a HardFault in the LPC17xx SSP driver. + +Additional minor fixes are also included as detailed in the ChangeLog. + +Several new features have been fully developed and included in this release, but +full verification of most of these new features has been blocked for a variety +of issues: + + * Added microSD support for the NuttShell (NSH) configuration in the + Nucleus2G LPC1768 port. For reasons that have not yet been determined, + I have not successfully accessed the microSD card as of this writing. + * Two USB configurations were also added for the Nucleus2G board: One to + support the USB serial device and one for the USB mass storage device. + Some testing of the USB driver was performed, but full verification is + stalled for an OTG style USB cable. + * LEDs now work correctly on the Nucleus2G LPC1768 board. + * The NuttX/uIP networking subsystem now supports IGMPv2 client. IGMP + (Internet Group Multicast Protocol) network "appliances" to join into + multicast groups. 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. |
