The LabVIEW FPGA Module 2011 f1 patch resolves the following issue:
ID | Fixed Issue |
308756 | Potential Data Corruption with NI FlexRIO DRAM, NI-XNET C Series modules, and CANopen C Series modules |
An internal component of the LabVIEW 2011 FPGA Module can generate VHDL containing a race condition that could lead to a potential data corruption when using certain LabVIEW FPGA hardware targets. This race condition could be present when running a LabVIEW FPGA design with any of the following characteristics:
When using NI FlexRIO DRAM, the result of this issue could be lost data, corrupt data, or overwritten data without notice. When using the NI-XNET or CANopen C Series modules, the result could be incorrect frames returned from the module.
If you are using the LabVIEW 2011 FPGA Module along with the FPGA Memory Item interface to DRAM, an NI-XNET C Series module, or a CANopen C Series module, it is highly recommended that you install the patch.
This issue is only present in the LabVIEW 2011 FPGA Module. All previous versions are not impacted.
