To build the code, select the Rebuild All menu item from the Project menu. To load the code through the JTAG debugger onto the connected evaluation board, select the Debug menu item from the Project menu.
7.3 Enabling the uC/OS-II Kernel Awareness When running the IAR C-Spy debugger, the μC/OS-II Kernel Awareness Plug-In can be used to provide useful information about the status of μC/OS-II objects and tasks. If the μC/OS-II Kernel Awareness Plug-In is currently enabled, then a μC/OS-II menu should be displayed while debugging. Otherwise, the plug-in can be enabled. Stop the debugger (if it is currently active) and select the Options menu item from the Project menu.
7.4 Running the Example Application The example projects include a basic demonstration of the µC/OS-II and µC/Probe. After you load the sample project to the phyCORE-LPC3250, the LEDs will start to blink. Text will be output to the lower RS-232 port (at 115200 baud) giving the state of the system as shown in the HyperTerminal screen capture below. The push buttons can be used to change the output to a new item.
7.5 Using the uC/Probe Example Workspace µC/Probe is a Windows program which retrieves the values of global variables from a connected embedded target and displays the values in an engineer-friendly format. To accomplish this, an ELF file, created by the user’s compiler and containing the names and addresses of all the global symbols on the target, is monitored by µC/Probe.
Next, select the RS-232 item in the options tree, and choose the appropriate COM port and baud rate. 1. Start Running. You should now be ready to run µC/Probe. Just press the run button ( ) to see the variables in the open data screens update. Figure 7-3 displays the phyCORE-LPC3250 IAR Rapid Development Kit data screen where the pushbuttons state and the serial output are being monitored.
You have now successfully installed and downloaded the µC/OS-II example demo, enabled the µC/OS-II Kernel Awareness Plug-In in IAR EWARM and used μC/Probe as a debugging and monitoring tool Published by PHYTEC America LLC 2009 Ordering No.
