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.
