Return
LabVIEW generated C Code might not compile on multi-byte versions of Microsoft Windows
On multi-byte versions of Microsoft Windows such as the Japanese version of Windows XP/Vista/7, VisualDSP++ cannot compile the C files that LabVIEW generates.

Workaround: N/A

Reported Version: 2009  Resolved Version: N/A  Added: 11/10/2010
Controls and Indicators
253778

Return
Controls and Indicators of Complex_float type do not exchange data with the Block Diagram
Controls and Indicators of Complex_float type do not exchange data with the Block Diagram. Wires connected to controls will always carry default values. Wires connected to Indicators will show results when probed but these results will not update the corresponding Indicators on the Front Panel.

Workaround: N/A

Reported Version: 2009  Resolved Version: N/A  Added: 11/10/2010
Example Programs
193593

Return
BF533 Web LED.lvproj is listed in the Example Finder but is not installed with the module
BF533 Web LED.lvproj is listed in the Example Finder (Toolkits and Modules>>Blackfin>>Fundamentals). However, double-clicking on the example brings up an error dialog. This example is not installed by the LabVIEW Embedded Module for Blackfin Processors.

Workaround: A similar example does exist for the BF536 target, you can find it at \examples\lvemb\Blackfin\BF536\Web LED. You can change the target in the Project Explorer from BF536 to BF533 to target your BF533 EZKit.

Functions, VIs, and Express VIs
250097

Return
Timed loops do not run with specified timing in certain conditions
When Timed Loops are configured with the 1 MHz time source and the "Discard missed periods" and "Maintain original phase" checkboxes are checked, your timed loop may run with rate that is different from the specified rate.

Workaround: Do not have both the "Discard missed periods" and "Maintain original phase" checkboxes checked at the same time if you are using the 1 MHz time source.

Reported Version: 2009  Resolved Version: N/A  Added: 11/01/2010
190016

Return
Using Event Structures inside Timed Loops might cause unexpected behavior on a BF548 EZKit
If you have an Event Structure inside a Timed Loop, the loop might not always wait for the event structure to execute. A While Loop with an Event Structure inside it also shows similar behavior when there is another running While loop in parallel with it on the Block Diagram.

Workaround: Avoid using Block Diagram constructs as mentioned above.

Reported Version: 2009  Resolved Version: N/A  Added: 11/10/2010
LabVIEW Project
163553

Return
Closing the project during a debugging session does not stop the session
When debugging using the JTAG/USB EZ-KIT, closing the project does not stop the debugging session. Closing the VI manually crashes LabVIEW

Workaround: Terminate the debugging session before closing the VI or the project
