RTOS: CMXKAware Kernel Awareness
Embedded systems engineers have long desired the ability
to view their programming applications running under an RTOS
via their debuggers. To meet this important need, CMX has developed
CMXKAware, which integrates seamlessly with a number of the
embedded software industry's leading development tool environments.
The result is a dramatically enhanced debugging capability that
helps to minimise application development time, thereby reducing
time to market for companies that manufacture products that
include embedded systems.
CMXKAware is a DLL or ORTI (OSEK Run Time Interface) that presents
all of the RTOS-specific information on the screen. CMXKAware
allows you to display CMX-RTX's internal data structures in
a convenient series of lists in the RTOS window of the debugger.
This provides you with information about each of the active
tasks in the target application, about each semaphore, resources,
mailbox, queue and event flag group along with a list of all
the tasks waiting on these kernel objects, and more. Data can
be displayed graphically in real-time.
The OSEK Run Time Interface (ORTI) for CMXKAware is a universal
interface for development tools to the CMX-RTX RTOS. This powerful
and flexible interface allows for the evaluation and display
of information about CMX-RTX, its state, its performance, the
different task states, the different operating system objects
etc. The object information is provided via an ASCII text file
and since these implementations are configured statically, this
data will be available at compilation. Additionally, the ORTI
file contains dynamic information as a set of attributes that
are represented by formulas to access corresponding dynamic
values. Formulas for dynamic data access are comprised of constants,
operations, and symbolic names within the target file. By performing
a continuous scan of the internal data structures described
in the ORTI file, debugging tools can extract and display critical
kernel-relative information, such as task states and event traces
for the last four RTOS calls in the application under test.
Further, the CMXKAware ORTI Builder automates the creation of
ORTI files adapted to the CMX-RTX RTOS for debugging purposes,
thereby allowing embedded engineers to focus their efforts exclusively
on debugging their application.
Since the DLL or ORTI utilises the kernel aware API no target
resources are used. Most debuggers are supported.

TCP/IP for 8-bit, 16-bit and 32-bit Embedded Processors
CMX-MicroNet has been developed by the company that is famous
for providing complete, elegant solutions to the embedded community -
CMX! CMX's developers have the expertise and hands-on experience
to satisfy the most stringent real time demands that the 8-,
16-, and 32-bit community deals with every day. When we set
about the task of creating the first true TCP/IP stack for these
popular processors, we knew that it had to have:
Only Industry Standard Protocols. Of what benefit are closed,
proprietary protocols that constrain and confuse your development
team? CMX-MicroNet offers only industry standard protocols running
right on your target processor and we provide full source code
with every sale!
Use your Current Processor. Why should you have to upgrade your
current processor, or, worst yet, add another processor just
for TCP/IP? Those hardware costs can really add up! CMX-MicroNet
allows you to work with your current design and still implement
the networking connectivity you need.
An Affordable Pricing Structure.
CMX-MicroNet offers a low, one-time fee and no royalties on
deployed products. And you get the entire source code for free
with every purchase!

CMX TCP/IP Stack: CMX-TCP/IP
High performance TCP/IP implementation
CMX-TCP/IP is a portable high performance TCP/IP implementation
for embedded systems. Memory usage is localised and deterministic.
It uses the CMX-RTX RTOS signaling mechanisms to provide a true
multitasking reentrant stack. CMX-TCP/IP can also be run without
an RTOS and all of the code is written to make it easy to switch
between modes without extensive source-code changes.
Most network protocols and applications are available, from
BOOTP all the way up to HTTP. There are also test applications,
such as a benchmark server or a ping tester, as well as a few
others. A consistent command shell debug facility for all modules
allows for the interactive execution of debugging commands and
setting debug levels of particular modules via a serial port
or Telnet connection which can be a real plus when bringing
up new Ethernet hardware, etc. At production time, you may simply
link with the non-debug version of the libraries for maximum
memory efficiency.
CMX-TCP/IP Kit includes:
- IP, ICMP/Raw IP, TCP, UDP, ARP, SNTP, DNS name
resolution.

Flash File Systems
CMX-FFS is the standard edition
flash file system for embedded systems developers and includes
100% Failsafe, Multiple volumes, Wear-leveling, Directories,
Boot sector support, and Standard drivers for NOR Flash chips
as well as RAM. CMX-FFS-NAND is a NAND Flash driver that also

File API - The file API is a standard interface. All the interface routines are fully re-entrant and provides all standard features for file manipulation such as fopen, fwrite etc. As well as routines for directory manipulation such as mkdir, chdir.
Intermediate File System - This is the control room of the file system. Although the source code is supplied, its detailed operation is not normally the concern of developers using the system. This section does all types of maintenance such as FATs, CRC’s, Bad blocks etc.
Driver Layer - Specific drivers control access between the Intermediate File System and the Physical media. These are kept as simple as possible and generally only need to have minor modifications made to constants to reflect particular flash array configurations and flash chip types.

CMX-FFS-TINY is a full-featured flash file system targeted at embedded devices with limited resources available to them and a requirement to reliably store and retrieve data from Flash devices including ST Serial, Small Sector Byte Writable, SST and DataFlash.
Flash devices are inherently complex and every flash type has different characteristics. Each flash type is analysed and a specific version of CMX-FFS-TINY is designed. The result is that the features of a particular device are hidden from the developer. Data can be stored position independently without having to worry about partial writes, partial erases, cumulative erase times and other flash details.
CMX-FFS-TINY opens up new possibilities for developers delivering reliable storage on the smallest devices without having to be flash or file system specialists.
CMX-FFS-FAT is a full-featured, PC compatible file system for embedded device developers who wish to add devices to their products that require FAT12/16/32 compliant media to be attached to them. Typical applications include adding a Secure Digital, Compact Flash or a Multimedia card to a device. The system includes pre-tested sample drivers for ease of development. The API is standard and easy to use with sample applications in source code provided to ensure quick integration. Hardware reference designs are also available.

The footprint of the CMX-USB-BL is less than 4k
bytes and can be held as a permanent, reliable boot-stub
on a single small sector flash which handles all
future firmware upgrades.

CMX-USB OTG
The CMX-USB suite offers an optional OTG (On-The-Go) Module
for applications whereby two devices must negotiate and decide
which will act as a USB Host and which will operate as a USB
device. The CMX-USB-OTG module is available for those processors
which are equipped with an OTG controller that supports the
HNP and SRP protocols which are used for USB host and USB device
negotiation.
More often, embedded applications that require both USB host
and USB device capability require dual mode operation. In dual
mode, when a USB host is inserted, the host stack will start
and when a USB device is inserted, the device stack will respond.
This is accomplished by recognition of the ID pin on the USB
OTG connector and is supported by CMX USB host and device stacks.
For dual mode operation, OTG software is not required.
