eCos®
is distributed under the GPL license with an exception which
permits proprietary application code to be linked with
eCos without
requiring that it also falls under the GPL. It is royalty and
buyout free.
-
eCosPro®
extends the functionality of
eCos to provide a
rich set of features as well as additional platform and device drivers
support. eCosPro
features as well as additional platforms and device drivers
can be found on the
eCosCentric web site.
-
eCosPro Developer's Kits combine the
stability, feature set, and quality of support required for commercial
embedded application development with eCos
by professional developers of embedded hardware devices.
- As an Open Source project, eCos is
under constant improvement, with an active developer community, based
around the eCos community web site at http://ecos.sourceware.org/.
- Powerful GUI-based configuration system allowing both large and
fine grained configuration of eCos. This
allows the functionality of eCos to be
customized to the exact requirements of the application.
- Full-featured, flexible, configurable, real time embedded
kernel. The kernel provides thread scheduling, synchronization,
timer, and communication primitives. It handles hardware resources
such as interrupts, exceptions, memory and caches.
- The Hardware Abstraction Layer (HAL) hides the specific features
of each supported CPU and platform, so that the kernel and other
run-time components can be implemented in a portable fashion.
- Support for µITRON and POSIX Application Programmer
Interfaces (APIs). It also includes a fully featured, thread-safe ISO
standard C library and math library.
-
eCosPro Developer's Kits include
additional features, such Symmetric Multi-Processing (SMP) for
ARM and Cortex-A, as well as eCos libraries and packages,
such as full standard C++ library support, BootUp, Robust Boot
Loader (RBL), FlashSafe API for high-reliability, data logging,
additional filesystems (multi-threaded FAT, JFFS, MMFS, YAFFS)
and more.
-
eCosPro Developer's Kits also provide
Eclipse-based IDE (Linux or Windows based), with eCos embedded-target
support.
- Support for a wide variety of devices including many serial
devices, ethernet controllers and FLASH memories. There is also
support for PCMCIA, USB and PCI interconnects.
- A fully featured TCP/IP stack implementing IP, IPv6, ICMP, UDP
and TCP over ethernet, as well as a lightweight IP stack (
lwIP) designed
for embedded systems. Support for SNMP, HTTP, TFTP and FTP are also
present.
- The RedBoot ROM monitor is an application that uses the
eCos HAL for portability. It provides
serial and ethernet based booting and debug services during
development.
- Many components include test programs that validate the
components behaviour. These can be used both to check that hardware is
functioning correctly, and as examples of
eCos usage.
-
eCos and eCosPro
documentation include this User Guide, an Installation Guide, the
Reference Manual and the Components Writer's Guide.
