有没有使用过eCos的啊，看起来很好哦。是red hat公司的产品，开放源码，可配置的，支持在windows下开发嵌入式操作系统。

以下是简介：
Welcome to the 1.3.1 release of Red Hat eCos(TM) - the Embedded Configurable Operating System.

What\'s New in 1.3.1?
In this, the third major public release of eCos, we have added a wealth of new features, enhancements, and have further extended the target platform coverage.

The configuration system has been completely revised and updated. Major new elements include:


Package management that supports the extension of eCos functionality via third party add-on packages.

A standardized configuration save file format that is human readable and editable, and compatible between both GUI and command line configuration tools.

Enhanced web based help and component documentation system integrated into the GUI configuration tool.

The Component Definition Language (CDL) has been radically revised and has now been implemented as a TCL extension for maximum flexibility. CDL is now fully documented in the Component Writers Guide.

Template support for straightforward control of multiple configuration elements, which can be used to provide easy access to standard eCos configurations such as a debug stub boot ROM.

Best of all, the source of the new configuration tools and underlying libCDL technology has been open sourced under the GNU Public License (GPL).
A companion beta version of the eCos TCP/IP stack has been released in conjunction with 1.3.1. The stack is derived from the OpenBSD source base and provides UDP, TCP, ICMP and BOOTP protocol support on an IPv4 standards base. Device driver support for Cirrus Logic EP72xx evaluation boards and Motorola MBX is included. The stack, ethernet core support, and device drivers are all distributed as configurable eCos packages.

A PCI bus support library has also been added that provides generic PCI bus based device initialization, discovery, and configuration. The library has been ported to both the VR4300 DDB-VRC4373 and StrongARM EBSA285 development boards.

New architectures and platforms added in this release include:


ARM Thumb

ARM9

Cirrus Logic CL-PS7111 and EP72xx

Cogent CMA222 and CMA230 ARM boards

是吗？你可以编译吗？

是吗？你可以编译吗？

我正在下载，东西比较多。我想应该可以编译的。

是吗？可以编译了告诉我一声。

行了吗？

I have been using eCOS for one year, it is good coz you can have the source code without charge.

你用的什么CPU?

能用在摩托罗拉的PowerPC上吗？

好象可以，不过我没找到工具链在哪下载。

别急别急慢慢来！
