Complete the following steps to debug the Blackfin tutorial application 
with breakpoints and probes.

1.

Switch to the block diagram if it is not visible.

2.

Right-click the Multiply function and select Set Breakpoint from
the shortcut menu. The breakpoint is highlighted with a red border 
around the function. When you run the Blackfin application, execution 
pauses just before the function executes. If you are using JTAG or 
USB/EZ-KIT for debugging, LabVIEW might prompt you to halt the 
processor.

3.

Right-click Debug configuration in the Project Explorer window 
and select Debug from the shortcut menu. LabVIEW prompts you to 
save changes to the VI. LabVIEW also prompts you if you need to 
rebuild or redownload the Blackfin application to the Blackfin target.

 LabVIEW uses default values for controls and indicators when building a Blackfin 

VI into a Blackfin application. To change the initial values, enter the new values in the front 
panel controls and then select Edit»Make Current Values Default to change the initial 
values. You must rebuild the Blackfin application after you change the initial values of the 
controls.

The Blackfin tutorial application begins running on the Blackfin target. 
When you reach a breakpoint during execution, the Blackfin target 
halts all operation, the application pauses, and the Pause button, shown 
at left, appears red and changes to a Continue button.
