ID Description
366114 DMA FIFO replaces data with zeros in certain configurations.


When a DMA FIFO is configured to one of the configurations shown below, the stream will yield bursts of good data interleaved with bursts of zeros. The user has no way of knowing they are receiving bad data. The issue only affects the LabVIEW 2012 FPGA Module.

Only FIFOs with the following configurations are affected:

FIFO Type Element Size (Bits) Number of Elements Per Write FIFO Depth (Elements)
Target-to-Host / Peer-to-Peer Writer 8 2 128 K
Target-to-Host / Peer-to-Peer Writer 8 2 256 K
Target-to-Host / Peer-to-Peer Writer 8 4 256 K
Target-to-Host / Peer-to-Peer Writer 16 2 128 K
Target-to-Host / Peer-to-Peer Writer 16 2 256 K
Target-to-Host / Peer-to-Peer Writer 16 4 256 K
Target-to-Host / Peer-to-Peer Writer 32 2 128 K
