NuttX-5.19
|
|
----------
|
|
|
|
The 66th release of NuttX, Version 5.19, was made on March 12, 2011
|
|
and is available for download from the SourceForge website. This
|
|
release includes several new features in various states of integration
|
|
and maturity:
|
|
|
|
* 486SX QEMU port. This port supports the Intel 486SX architecture
|
|
using the QEMU simulator. Initial functionality is in place a
|
|
partially tested. There are still some outstanding issues with
|
|
timer interrupts.
|
|
* Platform specific application support. A new apps/ directory
|
|
appears in this port. This apps/ directory provides a mechanism
|
|
for applications using NuttX to have a highly customized
|
|
initialization process. It supports a set of end-user applications
|
|
than can be executed (1) standalone so you can have a fully
|
|
customized application startup, or (2) on top of NSH. Think
|
|
of it this way: In a buckled-up embedded application, your
|
|
end-user programs will probably have their own dedicated start-up
|
|
logic. But, during development, you might want to have you
|
|
applications available and executable from the NSH command line.
|
|
This apps/ add-on (and NSH hooks) was contributed by Uros to
|
|
accomplish just that.
|
|
* NSH was also extended to support application specific ROMFS
|
|
/etc/init.d/rcS start-up scripts. This feature, as well, as
|
|
all of the above-mentioned apps/ directory support was contributed
|
|
by Uros Platise
|
|
* Additional NSH improvements and bug fixes. See the Changelog
|
|
for details.
|
|
* This release also provides a new SLIP network driver. This
|
|
driver should support point-to-point network communications to
|
|
a host using TCP/IP or UDP. This driver is code complete, but
|
|
not tested in this release.
|
|
* New RAMTRON FRAM driver (contributed by Uros Platise)
|
|
* New generic 16550 UART driver.
|
|
* Cortex-M3 Power improvements: Waits for Interrupt (WFI) in idle
|
|
loop for reduced power consumption (LPC17xx and STM32 only -
|
|
contributed by Uros Platise))
|
|
* New waitpid() system interface.
|
|
* Additional bugfixes: pipes, stdint.h, STM32 SDIO and SPI drivers
