NuttX-0.3.16
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This is the 28th release of NuttX. This release includes the first
|
||
|
|
support for USB in NuttX. A set of USB APIs were added to support
|
||
|
|
USB device controller drivers and bindings to USB device class
|
||
|
|
drivers. The form of the interface was inspired by the Linux Gadget APIs.
|
||
|
|
|
||
|
|
At present USB device controller drivers are included for:
|
||
|
|
* The NXP LPC214x. This driver has been verified and is an early alpha
|
||
|
|
stage in quality.
|
||
|
|
* TI DM320. Coding for this driver is complete but it is completely
|
||
|
|
untested as of this release.
|
||
|
|
|
||
|
|
A controller-independent class driver is also included for:
|
||
|
|
* USB serial class device driver (emulates the Prolific PL2303
|
||
|
|
serial-to-USB adapter). This driver has only been verified with
|
||
|
|
the Linux host PL2303 driver.
|
||
|
|
|
||
|
|
Other new features include:
|
||
|
|
* Add an option to set aside a separate stack for interrupt
|
||
|
|
handling (ARM only). This is useful when memory is constrained,
|
||
|
|
there are multiple tasks, and the interrupt stack requirement
|
||
|
|
is high (as when USB is enabled).
|
||
|
|
|
||
|
|
A few bugs were also fixed:
|
||
|
|
* Fixed the frequency of system timer interrupts in the NXP LPC214x port
|
||
|
|
(off by 20x in nuttx-0.3.15)
|
||
|
|
* Fixed serial driver bugs related to (1) open counts and (2) recognizing
|
||
|
|
O_NONBLOCK on read.
|
||
|
|
* Fixed an error in read(); it was not setting the errno on errors returned
|
||
|
|
from the driver.
|
||
|
|
|
||
|
|
These changes were verified only on the mcu123.com NXP LPC2148 board
|
||
|
|
using with a Linux host. Please report any errors to me.

UPDATE
|
||
|
|
------
|
||
|
|
This release does not build for the ARM target when USB is disabled.
|
||
|

Here is the fix:
