| 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. |
