Perhaps what you are experiencing is related to that. You program the serial interface and you just install a ready available driver at the PC side. Press F7 or select “Build All” from the “Project” menu to build the demo application.

Switch to the debugging perspective. Now we are getting calls from our customers that somehow functions that worked a few weeks ago are now not responding.

The served RTOS stats page The RTOS stats page provides run time information on the state of each task within the system – including the stack high water mark the minimum amount of stack there has been available at any time since the task started executing.


Running the demo application Once again – please refer to the Eclipse ush and configuration instructions for more detailed information. This makes the page relatively fast to load.

The page will reload approximately every two seconds – depending on network load. After installing the driver, it can be tested by using the SAM-BA application software on the PC, or by using a terminal emulator as shown here. DS4 toggling every 5 seconds indicates that all the standard demo tasks are executing without error. Users must familiarise themselves with the respective licenses. The target hardware will serve the web pages described below to a standard web browser. Thread aware file system Hint: Use the dialog box to navigate to the folder containing the driver.
