Selecting the flash debug configuration Running the demo application The IAR port cannot be executed using the IAR simulator so must be executed on the target hardware. In addition there is a uIP task that implements the embedded web server, a ‘Check’ task and the idle task.

If this is the case, then it is also likely that at91sak7x256 project file has been silently corrupted and will need to be restored to its original state before it can be built even with an updated IAR version. Functionality The demo application creates 33 tasks – consisting predominantly of the standard demo application tasks see the demo application section for details of the individual tasks.

Therefore a ‘Check’ afm is created whose job it is to ensure that no errors have been detected in any of the other tasks. The demo applications included in the FreeRTOS download switch to supervisor mode prior to main being called. Each receive buffer is bytes. This table is interesting for demonstration zrm, but as it is necessary to leave interrupts disabled for an extended period during its creation it is not recommended for use in applications with strict real time requirements.

You must ensure that the configured MAC address is unique on the network to which the prototyping board is being connected. Not all the tasks update an LED so have no visible indication that they are operating correctly. This site required JavaScript to be enabled. Fail Safe File System: This demo – Consists entirely of open source software.

Thread aware file system. This must be set appropriately for your hardware. The lwIP stack implements a more flexible complex memory management scheme, therefore the lwIP demo application contains a more comprehensive EMAC driver. This is demonstrated by the sample CGI scripts included in the source code download.

See the uIP documentation for further information. Demonstrates the creation of dynamic data with a simple CGI scripting language written by Adam Dunkels.

Ensure an Ethernet cable is connected as described above. Users must familiarise themselves with the uIP license. The prototyping board should also allow the use of a standard Ethernet cable when connecting point to point, but I have not tested this configuration.

Open a web browser on the connected computer. Thread aware file system Hint: Creates 31 of the standard demo tasks in addition to the web server task and the idle task. The semaphore immediately unblocks the uIP task, which processes the data and if necessary generates a response. Use the tree menu to navigate groups of related pages. Att91sam7x256 interaction is further simplified by the single buffer memory management of uIP.

The CGI script used to generate the table of tasks transmits the entire table in one packet and therefore loads quickly. When executing correctly the demo application will behave as follows: When a buffer is available for processing an EMAC interrupt is generated.

The driver included in the download uses the EMAC in its most basic configuration.

Entering the IP address into the web browser obviously use the correct IP address for your system. Simply open the rtosdemo. For example, if the web browser computer uses IP address The target hardware will serve web pages to a standard web browser.

This can be ensured by making the first three octets of both IP addresses identical.
