DS4 toggling every 5 seconds indicates that all the standard demo tasks are at91sam7xx without error. The IP addresses used by the web browser computer and the prototyping board must be compatible. It therefore contains many more files than used by this demo.

Udb error message should only appear on the first attempt. These tasks consist predominantly of the standard demo application tasks see the demo application section for details of the individual tasks.
Note that this functionality will only work when running the demo ‘stand alone’, without the debugger. The target hardware will serve the web pages described below to a standard web browser. Reset or initialize target before resuming “.
Fail Safe File System: This makes the page relatively fast to load. If you then wish to commence a debugging session: Note to Linux users: Please read the usage information provided on the linked page!

At91sam7xx the demo application Again – please refer to the Eclipse installation and configuration instructions for more detailed information. The uIP task This task handles all the network processing.
Entering the IP address into the web browser obviously use the correct IP address for your system. Press F7 or select “Build All” from the “Project” menu to build the demo application. Open a web browser on the connected computer. The ‘check’ tick hook A tick hook function is used to monitor the standard demo tasks – with LED DS4 being used to indicate the system status. Click here to view a static menu. This demonstrates how memory usage can be optimised through the use of a small transmit buffer by sacrificing the achieved data throughput.
The demo application uses the LEDs built into the prototyping board so no uxb hardware setup is required. When executing correctly the demo application will behave as follows: Running the demo application Once again – please refer to the Eclipse installation and configuration instructions for more detailed information.
This wt91sam7x the directory to select when prompted for a workspace location during the Eclipse startup process. Users must familiarise themselves with the respective licenses.
Note that the LED DS4 is also under control of the ‘check’ tick hook so will toggle every 5 seconds at91san7x overwriting any commands sent from the web server. It will spend most of its time blocked on a semaphore – waiting to be woken by interrupts generated by incoming network packets.
See the Embedded Ethernet Examples List page for more information.
The toggle rate increasing to ms is indicative of an error having been found in at least one demo task. The continuous reloading can sometimes make navigating away from the RTOS stats page a little tricky. Please follow these instructions carefully to install and configure Eclipse correctly for use with this demo application. The prototyping att91sam7x should also allow the use at91sam77x a standard Ethernet cable when connecting point to point, but I have not tested this configuration.
Be sure to read the Eclipse installation and configuration instructions prior to building the project. The page will reload approximately every two seconds – depending on network load.
