See the Source Code Organization section for a description of the downloaded files and information on creating a new project. The file demo. The web server and the lwIP initialization code is in web. If your are not using an MCF processor you will need to make some changes here. This includes crt0. S , init. S and serial. The files mcf5xxx.

S and newlib. They should also be replaced by the ones matching your target system. The port uses lwIP 1. If you have a different location change the Makefile. You can use the patches written by me which are available on the patches tab of the website. If the network controller does not support DMA, there is one copy operation, from the buffer in the network controller to the smxNS buffer in memory. Use of the zero-copy interface is demonstrated in example code that ships with smxNS.

A network interface is defined as a physical connection to a network e. Ethernet or to a serial link. Several state display functions allow easily checking the operation of features implemented in an application and tracking down unexpected behavior.

A choice of Ethernet drivers and link layers is available for smxNS. Customers outside the United States should contact Micro Digital to discuss the current arrangements regarding export licensing for these cryptographic functions. A rich selection of other network protocols is available for use with smxNS. The following is a brief discussion of each.

This is not intended for use as a general purpose browser, but rather as a mechanism for automated retrieval of information that is available via a web page, for configuration and control of a remote device. This is more efficient than broadcasting messages to all hosts in a network.

Multicast DNS is a protocol that allows a host on the network to discover services provided by other hosts. For example, a desktop computer could find a printer on the network without requiring the user to enter the address of the printer.

This allows you to create products that simply plug in to a network to add services. This design allows flexible out-of-band management of the NICs and is applied in certain networking equipment.

It supports MIME attachments. A dialer and sample dial-up scripts are included, as well as a runtime script interpreter that allows the system to be tailored to proprietary modems or ISP configurations. The system can be localized by pulling in certain script parameters such as a dial up number from non-volatile memory.

The smxNS PPPoE implementation requires virtually no more knowledge on the part of the end user than that required for standard dial-up Internet access. Network monitoring software is provided by other companies. This can be used to correct error in the local time source. The smxNS Web Server allows an embedded system to present real-time information to desktop or mobile web browsers. The web pages served by the system can be created using standard web design tools.

Once the set of HTML files have been created, the developer can include references to these files in the web server configuration file, and then run an included utility to convert the information into a data file. This data file can then be linked into the ROM section of the system image so that the web pages become part of the system. The SMX evaluation kits and product shipments that include the web server are supplied with a set of sample web pages and configuration files that can be customized and extended to become the web page content that ships with the final system.

When working with IAR tools, the project files that control the build can automatically invoke the conversion utility, so that the process is entirely accomplished within the IDE.

With CodeWarrior tools, the conversion utility is currently invoked by hand from the command line, and then the freshly converted data files can be built into the system image using the usual methods. Hence the interrupt priority has little or no effect on the system's behaviour. This is discussed in more detail below. Optionally the ethernet driver can maintain statistics about the number of incoming and transmitted ethernet frames, receive overruns, collisions, and other conditions.

The ColdFire processors do not have a built-in unique network MAC address since that would require slightly different manufacturing for each chip. All ethernet devices should have a unique address so this has to come from elsewhere. There are a number of possibilities:. When designing a new target board it is recommended that the board comes with a unique network address supported by the platform HAL, rather than relying on users to change the address. The latter approach can be error-prone and will lead to failures that are difficult to track down.

This separate chip handles the low-level details of ethernet communication, for example negotiating a link speed with the hub. In most scenarios the PHY chip simply does the right thing and needs no support from the ethernet driver. If there are special requirements, for example if the board has to be hardwired to communicate at 10Mbps rather than autonegotiate the link speed, then usually this is handled by fixed logic levels on some of the PHY pins or by using jumpers.

The eCos ethernet driver assumes that the PHY is already fully operational and does not interact with it in any way. If the target hardware does require software initialization of the PHY chip then usually this will be done in the platform HAL, because the choice of PHY chip is a characteristic of the platform.
